Introduction

A thesis or dissertation, as some people would like to call it, is an integral part of the Radiology curriculum, be it MD, DNB, or DMRD. We have tried to aggregate radiology thesis topics from various sources for reference.

Not everyone is interested in research, and writing a Radiology thesis can be daunting. But there is no escape from preparing, so it is better that you accept this bitter truth and start working on it instead of cribbing about it (like other things in life. #PhilosophyGyan!)

Start working on your thesis as early as possible and finish your thesis well before your exams, so you do not have that stress at the back of your mind. Also, your thesis may need multiple revisions, so be prepared and allocate time accordingly.

Tips for Choosing Radiology Thesis and Research Topics

Keep it simple silly (kiss).

Retrospective > Prospective

Retrospective studies are better than prospective ones, as you already have the data you need when choosing to do a retrospective study. Prospective studies are better quality, but as a resident, you may not have time (, energy and enthusiasm) to complete these.

Choose a simple topic that answers a single/few questions

Original research is challenging, especially if you do not have prior experience. I would suggest you choose a topic that answers a single or few questions. Most topics that I have listed are along those lines. Alternatively, you can choose a broad topic such as “Role of MRI in evaluation of perianal fistulas.”

You can choose a novel topic if you are genuinely interested in research AND have a good mentor who will guide you. Once you have done that, make sure that you publish your study once you are done with it.

Get it done ASAP.

In most cases, it makes sense to stick to a thesis topic that will not take much time. That does not mean you should ignore your thesis and ‘Ctrl C + Ctrl V’ from a friend from another university. Thesis writing is your first step toward research methodology so do it as sincerely as possible. Do not procrastinate in preparing the thesis. As soon as you have been allotted a guide, start researching topics and writing a review of the literature.

At the same time, do not invest a lot of time in writing/collecting data for your thesis. You should not be busy finishing your thesis a few months before the exam. Some people could not appear for the exam because they could not submit their thesis in time. So DO NOT TAKE thesis lightly.

Do NOT Copy-Paste

Reiterating once again, do not simply choose someone else’s thesis topic. Find out what are kind of cases that your Hospital caters to. It is better to do a good thesis on a common topic than a crappy one on a rare one.

Books to help you write a Radiology Thesis

Event country/university has a different format for thesis; hence these book recommendations may not work for everyone.

This technology enables physicians to look inside the patient to see anatomy, function and disease in its actual location, thereby improving diagnosis, disease assessment, treatment planning and procedure guidance. At IMMERS, we aim to bring together researchers and physicians across Stanford and work with industry partners to envision, enable, and enact solutions to real challenges in healthcare. Furthermore, we work to link numerous AR and virtual reality (VR) groups across campus for efficient collaboration.

The Proteomics Core Facility in the Canary Center at Stanford for Cancer Early Detection is a state-of-the-art mass spectrometry resource dedicated to the discovery and verification of blood-based protein biomarkers. This Core is developing and implementing a high throughput biomarker verification platform that exploits magnetic nanoparticle-facilitated immunoaffinity capture as a prelude to mass spectrometric biomarker quantification.

Radiochemistry and Cyclotron

The Radiochemistry Facility and Cyclotron are located on the first floor of the Lucas Expansion building. The cyclotron produces radioisotopes for both clinical and research use and is surrounded by an FDG production lab and research hot labs. Used for production of research radiopharmaceuticals that support clinical and PET studies at the Stanford University Medical Center and the SCI3, these hot labs also house radiochemistry research for the development of new radiopharmaceuticals.

Radiography science is a new discipline among health sciences. It is a discipline that investigates phenomena in medical imaging, radiation therapy, and nuclear medicine. It has merged from the need to provide research evidence to support these services. The domain of the discipline needs clarification and more research should be focused on its paradigmatic issues. Radiography research priorities have been previously charted on a national level in different countries but the viewpoint has been that of the needs of the profession, not of the discipline. This study aimed to identify the priorities of the discipline. The method chosen was a modified version of the Delphi technique with two rounds. The expert panel consisted of 24 European radiography researchers with long professional experience. This study shows that the research priorities in radiography science are related to the phenomena of radiographers' profession, clinical practices, and the safe and high‐quality use of radiation and technology for medical imaging, radiotherapy, and nuclear medicine. Identifying these priorities can help focus research onto most important topics and clarify disciplinary perspective.

The research priorities in radiography science are related to the phenomena of radiographers' profession, clinical practices, and the safe and high quality use of radiation and technology for medical imaging, radiotherapy, and nuclear medicine
Eight research topics were rated high in importance. These were the benefits of using artificial intelligence in radiography, safe integration of artificial intelligence into practice, impact of new technology, evidence‐based clinical practices, radiation safety, radiation optimization, patient outcomes in medical imaging, and image interpretation.
Radiography science differs from other health sciences in its priorities

1. INTRODUCTION

The European Commission's Horizon Europe ( 2021 ), a major funder of health research, includes in its policy aims finding new ways to keep people healthy, and developing better diagnostics and more effective therapies. Almost all patients in health care go through diagnostic examinations at some stage of their care pathway. Medical imaging rates are increasing due to innovations in technology and treatment methods (Smith‐Bindman et al., 2019 ), new applications in screening (Fedewa et al., 2021 ), the rising number of older people (United Nations, 2019 ), and increases in multimorbidity (Head et al., 2021 ) and in cancer cases (Tanskanen et al., 2021 ). Cancer is a growing health problem, and radiotherapy is used in cancer treatment in about 50 per cent of cases (Baskar et al., 2012 ). Radiography is an allied health science acting in the field of diagnostic imaging and radiotherapy. The knowledge base in radiography science is a combination of patient care and high technology and consists of medical imaging, radiotherapy, and nuclear medicine (Lundgren et al., 2015 ). Research in radiography has a long history, but as a discipline of its own it is still evolving. Rapid changes in the field set demands for high‐quality research, which is difficult to execute without solid foundations and a clear disciplinary perspective. It would be vital to conduct research from the discipline's own paradigm to develop clinical practices at the grass‐roots level where the patients encounter the diagnostic and therapeutic services. Radiography science in Europe is not a unified discipline. There are differences in the education, curricula, and research practices (Couto et al., 2018 ; McNulty et al., 2016 ). Advantages of a unified discipline would be closer research collaboration between researchers and academic institutions offering radiography as a discipline, better understanding of what the focus of the discipline is and its philosophical assumptions, not to mention the benefits of sharing limited research funding of small subspecialties. In order to clarify a unified disciplinary perspective, it is important to identify the research priorities of radiography science.

1.1. Background

Radiographers consider their own research important but are not actively involved in research (Vikestad et al., 2017 ). The number of radiographers with a doctorate degree is around 0.1 to 0.3 per cent of the workforce (Andersson et al., 2020 ; Ekpo et al., 2017 ). This is significantly lower than the number of nurses with doctorates, around 1 to 1.9 per cent of the workforce (Rosenfeld et al., 2022 ; Orton et al., 2020 ). There is an active research community in the discipline but the majority of the published articles are from a small group of researchers (Snaith, 2013 ). Radiographers are engaged in research activities as assistants or collectors of data but many studies are led by other professionals due to radiographers' limited experience and confidence in conducting research (Saukko et al., 2021 ; Dennett et al., 2021 ). However, most radiography professionals tend to think that radiographers should conduct research and lead research projects (Saukko et al., 2021 ; Ooi et al., 2012 ). Advancement of research engagement would require knowledge about scientific methods, support from colleagues and other professionals, and a positive research culture in workplaces (Bolejko et al., 2021 ).In health sciences, research interests and priorities have been studied for reasons such as developing an informed set of research priorities (Shepherd et al., 2017 ), augmenting previously identified research priorities with a new group (Frankenberger et al., 2019 ), identifying research topics (Wielenga et al., 2015 ), developing a research agenda (Brenner et al., 2014 ), and prioritizing efforts and resources (Garner et al., 2021 ). In nursing science, research priorities have been set to both broad foci (such as health, practice, education, and leadership) and to various clinical categories (Strobehn et al., 2021 ). Research regarding dissertation topics in nursing identified quality of life, perception, job satisfaction, sleep, nursing roles, physical activity/exercise, turnover, leadership styles, simulation, and cancer as the most frequent topics (Strobehn et al., 2021 ). In the Nordic countries, research in nursing focuses mainly on patients' health problems (Lundgren et al., 2009 ). By contrast, in radiography, dissertations have focused on structural factors, clinical radiography, radiographic technology, and pedagogical approaches (Lundgren et al., 2019 ), indicating that radiography and nursing have diverging research priorities. The current discourse about radiography science resembles much of the discussion that nursing science faced in the early ages about its disciplinary perspective and focus (Lundgren et al., 2009 ).Areas of research interests for European radiography researchers have not previously been charted from the perspective of the discipline. Previous studies have explored the needs of the profession. Radiotherapists' research interests have been charted at the national level in Norway and Australia (Egestad & Halkett, 2016 ; Halkett et al., 2017 ). Studies in the research interests in radiotherapy indicate that the research interests are connected to patients, technical issues of radiotherapy, radiation safety, and issues of the staff (Egestad & Halkett, 2016 ). Research areas prioritized as most important were linked to the development of treatment techniques and their benefits and side effects to patients, as well as to concerns of the radiotherapist profession (Cox et al., 2010 ). Researchers have also stated patient focus and patient outcomes in radiotherapy as areas of research interest (Halkett et al., 2017 ).The College of Radiographers ( 2017 ) studied research priorities for the radiographer profession in the United Kingdom. A Delphi expert panel reached consensus in 133 priority areas. Five key themes for research were identified. These were technical innovations, patient and public experience, service and workforce transformation, accuracy and safety, and education and training. The Society of Radiographers working group for artificial intelligence (AI; Malamateniou et al., 2021 ) found that radiography research priorities should be set to investigate the impact of AI technologies on patients in medical imaging and radiotherapy, radiographer role development, and the development of practices with emerging AI‐based technology. In Finland, the research focus in radiography science is reportedly in clinical radiographers' work, technical radiation usage and radiation protection, patient care and service, and service for a health care context (Sorppanen, 2006 ). Metsälä and Fridell ( 2018 ) found that radiography science primarily has technical and practical knowledge interests, but that critical knowledge interests exist as well.

In this study, our aim is to identify research priorities in radiography science. The objective is to chart the opinions of radiography experts. We ask three questions to guide this study:

Which research topics do radiography science experts in Europe consider important for radiography science?
Which research topic do they see as most important?
Which research topics do experts in the field of radiography agree upon?

Agreement on topics is achieved when there is a consensus. The topics that reach consensus and are rated as being of high importance are considered the priorities of the discipline.

The Delphi technique was selected as the method. The Delphi technique is a widely used method in health sciences and it has been used in developing guidelines and establishing research priorities. The Delphi technique is characterized by the use of an expert panel, the members of which are anonymous to each other, and iterative rounds with feedback and the opportunity to alter one's opinion. The classical Delphi technique has at least three successive rounds but modified variations are numerous. The classical Delphi technique starts with an open first round (Varndell et al., 2021 ). The benefit of using a Delphi technique is the possibility of having an anonymous group opinion from a wide geographical area. It is especially suitable when there is a lack of agreement or incomplete knowledge (Trevelyan & Robinson, 2015 ). The Delphi technique has been widely used in identifying and building consensus on research interests and priorities in health sciences among health care professionals (e.g., Shepherd et al., 2017 ; Frankenberger et al., 2019 ).

2.1. Design

A modified Delphi method with two rounds was performed. Instead of an open first round, we used a scoping review as the starting point of our study. In an earlier study (Törnroos et al., 2021 ), we identified 117 research interests for radiography science. They formed the basis of the first‐round questionnaire. Some of the similar items were further merged by two authors (S.T. and E.M.) and eventually 84 items were included in the first‐round questionnaire. The first‐round questionnaire was piloted in Finland in August 2021 by four radiographers with experience and training in research. They commented on the readability and clarity of the questionnaire. The comments concerned the instruction text for the questionnaire, background questions about the discipline, headings, and the size of the open‐ended answer box. The questionnaire was modified accordingly. The entire Delphi process is presented in Figure 1 .

2.2. Expert panel sampling

Experts were recruited through the European Federation of Radiographer Societies (EFRS). A recruitment invitation was sent by the EFRS to all member societies (40 national societies and 60 academic institutions of radiography education in Europe). The criteria for a panelist were (i) minimum of a bachelor's degree in any field of radiography (diagnostics, radiation therapy, or nuclear medicine); (ii) at least two published research articles in a scientific journal in the past 5 years; (iii) clinical work experience in the field; (iv) English‐language skills (reading and writing); and (v) willingness to participate voluntarily. A total of 29 experts answered the invitation, with all but one expert meeting all the criteria. The first round of the questionnaire was thus sent to 28 experts.

2.3. Data collection and analysis

Data were collected with the REDCap platform (hosted by the University of Turku). They were analyzed with IBM SPSS Statistics version 27. Categorical variables were summarized with counts and percentages. Variables did not follow normal distribution. High rankings on importance of the topics (6 or 7) were observed with most variables, with a few outliers distorting the mean. Median values and quartiles were thus selected to describe the level of agreement. The level of consensus was set to an interquartile range (IQR) value of ≤1. IQR is a measure of dispersion for the median. IQR of less than one means that more than 50% of all opinions are within one point on the scale. It is often used in Delphi studies as an objective way of determining consensus (von der Gracht, 2012 ). Stability of the responses between rounds was measured with a bootstrapped paired t ‐test, which is a valid test for two dependent samples with non‐normal distribution (Dwivedi et al., 2017 ). A p ‐value of >0.05 indicates that there is no statistically significant difference between the responses in round two. A smaller p ‐value would indicate that there has been a significant change in the response. To test whether experts' educational background or position at work had a significant effect on their responses, we used the Fisher's extended test. We were unable to use the chi‐square test because the expected number of answers per cell was under five.

2.4. Round one

The 84 research topics (items) in the questionnaire were structured under six categories identified in the scoping review: (i) radiographer's profession (17 items); (ii) clinical practice in radiography (31 items); (iii) safe and high‐quality use of radiation (12 items); (iv) technology in radiography (8 items); (v) discipline of radiography science (5 items); and (vi) management and leadership (11 items). Panelists were asked to rate the importance of the topic to radiography science on a 7‐point Likert scale (not at all important, unimportant, low importance, neutral, somewhat important, important, and very important), where 1 represents “not at all important” and 7 is “very important.” The questionnaire contained an open‐ended question after each category, asking if there ought to be any other topics in that category. The experts were also asked to give a rationale if they considered some topic important or very important. At the end of the questionnaire, there was an open‐ended question asking if there would be any other topics outside the six categories mentioned in the questionnaire.The experts rated all items and most of the items were rated important or very important (median of 6 or 7). Only 15 items were ranked below a median of 6. The experts presented 25 new research topics for the second round. Twenty‐three new topics were placed into existing categories but two of the new topics, veterinary radiography and forensic radiography, did not fit into any pre‐existing category and were placed at the end of the second round questionnaire.

2.5. Round two

In the second round, participants received a reminder of their own answers in round one, and the median answers of the entire expert panel and the range of the answers. Participants were asked to reflect on their own answer and they were given a chance to alter their opinion or remain with the same answer. All research topics (84) and the 25 newly generated topics from the round one answers were included in the second round for a second rating (see Appendix Table A1 for all items). The experts were also asked to choose one most important topic from each of the six categories.

2.6. Ethical considerations

The Ethics Committee for Human Sciences at the University of Turku granted ethical review approval (ref 21/2021). Informed consent was received from all participants and they were provided information on how their data was processed. All data were processed according to the European Union's General Data Protection Regulation (GDPR).

3.1. Demographics of the panelists

Of the 28 experts who indicated willingness to participate, 24 experts eventually (86%) responded to the first round. There was also some attrition between rounds, and only 20 experts answered (71%) for the second round, even though two reminders were sent. The expert panelists participating in the first round were from the United Kingdom ( n = 7), Norway ( n = 4), Denmark ( n = 3), Switzerland ( n = 3), Sweden ( n = 2), Hungary ( n = 1), Italy ( n = 1), Malta ( n = 1), Portugal ( n = 1) and Spain ( n = 1). The mean age of the panelists was 50 years (range 30–70). On average, they had been working 25 years in the field of radiography (range 2–48). They had each published between 2 to 36 scientific publications in the past 5 years, with the mean being 13 publications. There were 23 degrees higher than Bachelor's. Most of the panelists were academics, with only two working as a clinical radiographer or radiotherapist. Those who described their position at work as “other” were working as clinical consultants, senior advisers, or working in a professional association (Table 1 ).

3.2. The importance of the research topics after two rounds

Out of all research topics (109 items) under the six categories identified in the scoping review, there were eight research topics that gained a high median score of 6.5 or 7 after two rounds, and the experts were like‐minded in their answers. These eight were as follows: (i) the benefits of using artificial intelligence in radiography; (ii) safe integration of artificial intelligence into practice; (iii) the impact of new technology; (iv) evidence‐based clinical practices; (v) radiation safety; (vi) radiation optimization; (vii) patient outcomes in medical imaging; and (viii) image interpretation. Another 27 research topics were rated important, with a median score of 6 and an IQR of 1. Research topics in advanced practice and patient‐centered care were also rated high in importance (median 7) but the experts' opinions were divided on these topics and they did not reach consensus (IQR of 2). The lowest rated topics that reached consensus were multidisciplinary education, role and territory of radiography, ergonomics of radiographers, workplace well‐being, complementary medicine, and the impact of radiographers' gender on the profession. There were no significant differences in answers with relation to experts' educational background or current position at work. All items included in the second round and statistical analysis are presented in Appendix Table A1 .

The expert's rationales for the topics they selected as important or very important are presented next by the six categories identified in the scoping review, under which they were structured in the questionnaire. The topics chosen as most important in each category are also described.

3.2.1. Radiographers profession

The importance of these topics was primarily rationalized by the developing needs of the profession. As technology in medical imaging and radiotherapy advances, the demands for the profession rise and more research is required for the competences and education of the professionals. Eventually this will have an impact on patient outcome and experience. The development of the radiographer profession requires research in the area.

The technical development makes it very important to be ready to acquire new competence and work in changing organizations (multidisciplinary, new technology, new procedures, new demands on the profession, etc.). (Expert 5)

Development of the profession is important as technology changes. In addition, the quality of the professionals is important for the profession to evolve. (Expert 6)

3.2.2. Clinical practice in radiography

Evidence‐based practice was deemed important for avoiding unnecessary imaging and treatment, and to improve the services and the quality in clinical practice. Patient‐centered care should be a priority and it is important to hear patient voices regarding the services they need.

Good working practices, protocols and procedures are essential in creating time and space to concentrate on the patient and his/her experiences. (Expert 13)

The radiographers work with technology, so they must know well this aspect but at the same time the radiographers are the bridge between the patient and the machine and if the interaction is not optimized, the examination and/or treatment can be compromised. The interaction with other professionals is also important to be sure that we are providing the best diagnostic/therapeutic to the patients. (Expert 4)

3.2.3. Safe and high‐quality use of radiation

Radiation protection was said to be at the heart of radiography and patient safety and the main expertise area of radiographers.

Radiographers are the professionals to handle radiation. Therefore, research in radiation is naturally performed by radiographers. (Expert 8)

Recent advances in radiotherapy dose regimens to include ultra hypofractionated treatments for prostate and breast cancer warrant further investigation of side effects and the radiobiological effect. (Expert 19)

3.2.4. Technology in radiography

Research into technological development was seen as important, as radiography operates with high technology. There was discussion about radiographers taking an active role in its development.

AI requires robust, prospective research to assess performance in a clinical setting and how this will be safely integrated into future practice. (Expert 11)

Radiographers have a lot of room to grow in the field of new technologies. They must be among the actors of these developments and must not be only the users. (Expert 16)

3.2.5. Discipline of radiography science

Research into the discipline was deemed important for the development of the discipline and research.

Research is the only way to develop Radiography as a Science and what is involved in the discipline. (Expert 24)

Good research is founded on good methods. (Expert 14)

3.2.6. Management and leadership

These topics were mostly seen as important because of their connection to smooth operation of the clinical practice and well‐being.

Everyone contributes toward smooth workflow for patient care and health and well‐being of staff. (Expert 15)

These topics are important given their link to an advanced level of radiography practice. (Expert 7)

3.2.7. The most important topic in each category

In addition to rationales, experts were asked to choose the most important topic in each category. The opinions were divided between various topics. Most support was given to “evidence‐based clinical practices” backed up by seven experts and “radiation safety” by six experts. The research topics regarded as most important from other categories were “advanced practice,” “the benefits of using artificial intelligence in radiography,” “the importance of support programs for research activity,” and “communication issues.”

3.3. Research topics that reached consensus after two rounds

Forty‐one research topics reached consensus (Table 2 ) and sixty‐eight did not. There was very little change in the experts’ opinions between rounds; only five items had a statistically significant difference ( p < 0.05) between the first and second round. There were altogether 22 topics in the category of “radiographer's profession” and 8 of them had medians of 6 or over and an IQR of 1 (36% of items), the “clinical practice in radiography” category had 38 topics of which 15 had medians of 6 or greater (39% of the items), “safe and high‐quality use of radiation” had 15 topics and 6 of these had a median of 6 or over (40% of the items), “technology in radiography” had 12 topics with 5 having a median of 6 or greater (42% of the items), “discipline of radiography science” had 8 topics and only 1 received a median of 6 (13%), and in the category of “management and leadership” there were 12 topics but none of them received a median of 6 or over with an IQR of 1. Of these six categories, “radiographer's profession,” “clinical practice in radiography,” “safe and high‐quality use of radiation,” and “technology in radiography” had quite equal proportions of high‐ranking items, while the remaining two, “discipline of radiography science” and “management and leadership,” had but a single research topic between them that was rated important by the experts of this Delphi panel. Therefore, it seems that priority in research should not be given to research topics in these two categories.

4. DISCUSSION

The eight topics that received a high median of over 6.5 relate to the clinical practices and radiographers' profession, as well as to radiation safety and new technology in radiography. These are rather similar to the findings of the College of Radiographers (2017) for the research priorities of the radiographer profession: technical innovations, patient and public experience (about clinical practices), service and workforce transformation (in relation to advancing roles), accuracy and safety (quality and safe use of radiation), and education and training (of the radiographer profession). Similar priorities on technological development, radiation safety, patient outcomes and matters of the profession have been reported among radiotherapists (Halkett et al., 2017 ; Egestad & Halkett, 2016 ).The two topics related to artificial intelligence were rated high in importance. This is where Malamateniou et al. ( 2021 ) also recommended that priorities should be set. Artificial Intelligence‐based solutions in medical imaging and radiotherapy, and their effect on the entire discipline, including the role of the radiographer profession in the future, have been widely discussed in the radiography community for the past few years ( International Society of Radiographers and Radiological Technologists and the European Federation of Radiographer Societies, 2020 ). This might have influenced expert panelists' opinions. In the rationales given by the experts for the importance of the research areas, technological development—and in particular, the impact that rapidly developing technology has on clinical practices and the radiographer's profession—was often mentioned as the reason for conducting research in the field. When the development in the technology was used as rationale for investigating radiographers' profession, in those cases, the scope was in the competences required, rather than in the actual technology.Evidence‐based clinical practices were rated with a high median score of 7. Although discussion of evidence‐based practice, which began in the 1990s, soon came to include radiography as well (Hafslund et al., 2008 ), it still seems to be badly implemented in this field (Munn, 2020 ; Abrantes et al., 2020 ). The topic therefore is an ever‐relevant area for research. Research alone does not improve the situation; radiographers working in clinical practice would also require skills for implementation. The patient outcomes in medical imaging, another highly rated topic, relate to the same matter: how to secure effective imaging methods to improve diagnostics and eventually the patients' care. In radiation therapy, it is equally important to secure effective therapeutic procedures for the best outcome for patients.According to the expert panelists' reasoning, radiation safety and optimization are at the heart of radiography and radiographers' special expertise area. The topics were also rated high in importance. Radiation safety has improved over the years but there is still room for development and research. Constantly changing technology keeps radiation safety always topical. Even though radiation in health care is highly regulated, at least in the European Union ( 2013 ), there is indication that obsolete practices still exist (Maina et al., 2020 ; Ciraj‐Bjelac et al., 2011 ) and there are gaps in the knowledge of radiation protection measures (Faggioni et al., 2017 ).The eighth topic rated high, image interpretation, relates to a larger discussion on role extension and transfer of responsibilities from radiologists to radiographers. In the United Kingdom the role extension is well established (Hardy & Snaith, 2009 ), but there is ongoing debate surrounding the issue internationally due to a shortage of trained radiologists (van de Venter & ten Ham‐Baloy, 2019 ; Ofori‐Manteaw & Dzidzornu, 2019 ). Similar discussions of task‐shifting have been topical in other health sciences and we need more research in this area. It will be interesting to see how the rise of AI technology in image interpretation affects this discussion.Studies have shown that radiographers want to conduct research but lack the skills and confidence (Saukko et al., 2021 ; Dennett et al., 2021 ). Bolejko et al. ( 2021 ) propose a strategy for establishing a research culture that is enhanced by support from colleagues and management. We think that the implantation of research culture requires also a clear perspective of the domain of radiography science. Radiography science differs from nursing science and other health sciences in its priorities. Health and health‐related problems that are seen as priorities in nursing research (Strobehn et al., 2021 ; Lundgren et al., 2009 ) do not stand out as a priority in this study. Research into clinical practice is a shared research area in health sciences but the locus is in different areas. In the early years of nursing science, a lot of research and theories were focused on nurses and the actions they perform. As the discipline has matured, research has been directed toward the clinical problems of the patients and the essential phenomena of nursing (Tobbell, 2018 ). Radiography as a scientific discipline is still evolving, and in the future we might see the essential phenomena of radiography science emerging and the professional connection to a radiographer's work fade. In medical imaging and radiotherapy technology, change seems to be continuous. Research topics may vary over time but some phenomena that radiography science investigates are constant. Whatever improvements in technology there might be, it is important to translate the changes into clinical practice and in a manner that is suitable and safe for patients.

4.1. Limitations

The panelists of this Delphi study had a long professional history in the field of radiography and expertise in research. They represented different countries in Europe and different educational backgrounds. From some European countries there was only one expert in the panel and therefore we cannot make any generalizations that the results of this study would represent the opinion of the whole of Europe. Experts with diagnostic radiography education were over‐represented, constituting over half of the experts. Generally, of the European radiographers, about 63% have a combined qualification (diagnostic imaging, radiotherapy, and nuclear medicine), 34% diagnostic imaging only, and a small percentage are specifically qualified in radiotherapy and nuclear medicine only (McNulty et al., 2016 ). The research topics were previously identified through the literature, and the experts were asked to judge the topics in relation to their importance to radiography science (not to their own research field), so the over‐representation of diagnostic radiography researchers did not significantly bias the results. Of course, this might have had an effect on the prioritizing of research topics. It is possible that with a larger group of experts and wider geographical representation, the results of the study might be somewhat different. We received a confirmation from the EFRS that the invitation to participate in the study had been sent to all member organizations, but we could have enhanced the participation rates by advertising further.It is important to understand that achieving consensus does not mean that the correct answer has been definitively found (Keeney et al., 2006 ). For example, patient‐centered care, which has been recognized as an important research area in radiography (Halkett et al., 2012 ), was rated high in importance in this study, yet the topic did not achieve consensus. Some of the research topics might be more important to radiotherapists than to diagnostic radiographers and vice versa, but it was not the scope of this study to compare differences but rather to find commonalities that could be studied inside the discipline of radiography science. A further stated limitation of the Delphi method is a poor response rate in the sequential rounds (Keeney et al., 2006 ), and we also had a decline of participants in the second round. However, the response rate of 71% in the second round can be still considered sufficient.

5. CONCLUSIONS

This study has provided knowledge on research priorities of radiography science that are shared by experts of the Delphi panel, who were from different fields of radiography and different areas of Europe. Radiography science in this study is understood as a common field of inquiry that researchers in diagnostic imaging, radiotherapy, and nuclear medicine share. The priorities therefore are the research areas where a common ground, a consensus, can be found. We had previously discovered six main phenomena from the literature which radiography science investigates; however, the results of this study indicate that only four of them are priority areas for the discipline. The research priorities in radiography science are related to the phenomena of radiographers' profession, clinical practices, safe and high‐quality use of radiation and technology used in medical imaging, radiotherapy, and nuclear medicine. This finding is also supported by previous studies of priorities of the profession. There are several research topics inside these categories and the topics that received the most support from the experts were identified.

5.1. Relevance for clinical practice

The application of evidence‐based practices, and the development of diagnostic and therapeutic services provided in health care, require strong research evidence. This evidence can be produced with research done in radiography science. As we have now identified the priorities of radiography science, researchers in the discipline could focus their studies on these topics.

Radiology Research Topics

1. Revolutionizing Medical Imaging with Computed Tomography

Are you a medical imaging specialist looking to take your imaging capabilities to the next level? Look no further than high-precision computed tomography! Computed Tomography (CT) is an industry-leading medical imaging technology that provides clinicians with essential 3D images to diagnose potential illnesses as accurately as possible.

Using powerful x-ray beams and complex algorithms, CT scans create detailed internal images with far better resolution than most other diagnostic modalities, such as MRI or ultrasound. These highly intricate 3D depictions essentially act like a snapshot of the inner workings when scanning – making it easier for healthcare providers to detect problems related to cardiovascular diseases, cancer, trauma, infections, and soft tissue damage.

2. Gastro-Diagnostics: Taking an X-Ray of your Digestive System

This study will help you dive deep into the depths of your digestive system and take a good hard look at what’s happening inside you. The Gastro-Diagnostic system works safely and quickly to order special equipment for an endoscopy or colonoscopy procedure. This minimally invasive process involves only light anesthesia and is used for diagnostic purposes only — it does not establish any form of treatment.

Once complete, a radiologist will evaluate the results directly from the Imaging center via secure transfer to our facility. They are set up with full training and assistance in reading images securely online. The final diagnosis must be based upon a referral by physicians trained in this field of medical science

Radiation Revolution: An Inside Look at Diagnostic Radiology

Are you curious to learn more about diagnostic radiology? Well, this is your chance! With this study, you’ll get all the necessary information.

Diagnostic radiology is an advanced imaging technology used in hospitals, clinics, and physician’s offices worldwide. It uses specialized equipment to produce cross-section images of body parts and identify problems that cannot be seen by just taking x-rays. These images are then used to diagnose and treat conditions like cancer, heart disease, stroke, neurodegenerative diseases, musculoskeletal ailments, and more!

Opting for diagnostic radiology instead of traditional x-ray procedure allows doctors to detect subtle changes related to or unrelated health issues much earlier. It enables them to plan suitable treatments accordingly. Moreover, this sophisticated imaging tool provides detailed information about bodily organs, often serving as a guide before undertaking minor or major surgeries.

Magnifying Medical Miracles with MRI Technology

If you want to make medical miracles happen, it all starts with the right technology. Enter MRI technology – a powerful tool that gives doctors and physicians deep insight into human anatomy so they can effectively diagnose diseases and create successful treatment plans.

MRI stands for Magnetic Resonance Imaging, but we think of it as Major Resolution Imagery. Put simply; an MRI machine helps health care professionals locate problems ranging from fractures in bones to defects inside organs or arteries — something no other device on earth can do quite like this one! Plus, its cutting-edge imaging capabilities let them observe minute details without resorting to invasive surgery – true magnifying magic at work!

Exploring Ultrasonography Medical Imaging

Ultrasonography is a medical imaging technology that creates images of inside organs and structures by using high-frequency sound waves. It is commonly used to assess the health of a fetus during pregnancy and diagnose and monitor conditions such as heart disease, cancer, and kidney stones. Examples include obstetric ultrasound for pregnant women and echocardiography for assessing heart health.

This cutting-edge medical imaging technology has revolutionized how medical professionals view the body’s inner workings. With ultrasonography, you can view organs, tissues, and even unborn babies with unparalleled clarity and detail.

Role of RADS in Radiology

RADS stands for Radiology Assessment Database System. It is a system used by radiologists to store, manage, and analyze medical imaging data. Examples of popular RADS systems include PACS (Picture Archiving and Communication System) and RIS (Radiology Information System).

RADS also has powerful analytical tools that help you get the most out of your imaging datasets. It enables you to monitor patient outcomes, analyze diagnostic accuracy, and detect trends in image quality across your practice or institution. In addition, RADS includes a variety of reporting tools that let you generate custom reports and track results over time.

Deciphering Exposure Indicators through Radiology

Exposure Indicators in Radiology are measurements used to determine the amount of radiation exposure a patient has received during a radiological procedure. Examples of popular exposure indicators include the dose-area product (DAP) and the computed tomography dose index (CTDI). The DAP is a measure of the total radiation dose delivered to a patient during an imaging procedure. At the same time, the CTDI is a measure of the radiation dose delivered to a specific region of the body.

These indicators are incredibly accurate and reliable, precisely measuring the radiation dose a patient receives during a radiological procedure. With this information, you can ensure your patients get the required dosage without exceeding it.

Focal Spot/Area/Zone: Radiology

Do you want to get the most out of your radiology exams? This study will help you a lot!

Focal Spot/Area/Zone is a term used in radiology to refer to the area of the body that is being imaged. It is the area where the X-ray beam is focused and is usually the size of a pinhead. Popular examples include mammograms, which focus on the breast tissue, and CT scans, which focus on the head or chest.

Focal Spot/Area/Zone also provides safety benefits. With its pinpoint accuracy, radiation exposure time is limited and helps limit exposure to x-ray radiation. As a result, fewer images must be taken to get the desired results, reducing the risk to your patients.

An Exploration of Contrast Medium

A contrast medium is a material that is used to improve the visibility of organs, vessels, and tissues during medical imaging procedures. The procedures include X-ray, computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound. Popular examples of contrast media include barium sulfate for X-rays, gadolinium for MRI, and microbubbles for ultrasound.

Contrast medium helps in aiding quick diagnosis as it improves the accuracy and effectiveness of medical imaging procedures. The contrast medium lets your doctor get a detailed image for a great diagnosis. It also helps in warning about potential danger signs that may not be visible through standard imaging procedures.

Another advantage of using a contrast medium for medical imaging is its safety. It is FDA approved and noted to be safe for human usage.

10. A Clear Look at Mammography

A mammogram is a type of imaging test that uses low-dose X-rays to detect changes in the breast tissue. It is used to screen for and diagnose breast cancer and other conditions, such as cysts or benign tumors. Mammograms can also be used to monitor the progress of treatment for breast cancer.

Mammography involves squeezing the breasts between two plates and capturing an X-ray picture. This compression helps to spread out the breast tissue so that any abnormalities can be more easily seen on the X-ray image. The images are then sent to a radiologist, who will interpret them and report back with their findings.

11. A Guide to Abdominal Radiography

Abdominal radiography is an imaging technique used to view the internal organs and structures of the abdomen. It involves taking X-ray pictures of the abdomen, which can help diagnose various conditions such as gallstones, appendicitis, ulcers, hernias, and tumors. Abdominal radiography is also used to assess the abdominal organs’ health and monitor treatments such as chemotherapy or radiation therapy.

Whether you’re taking precautions or not sure what’s happening inside, abdominal radiography helps you and your doctor gain valuable insights into the health of your abdominal organs and provides an actual window into exactly what treatments — like chemotherapy or radiation therapy — are doing to make you feel better.

12. Marker Types – Nodules, Lesions, and Tumors:

Introducing the most comprehensive marker types – Nodules, Lesions, and Tumors! These markers provide a fast, easy and accurate way to identify different types of tissue changes with medical imaging and biopsy techniques.

Nodules are solid lumps that can form in any part of the body. They can be easily detected through CT, MRI, and ultrasounds. Lesions are an area of abnormal tissue caused by injury or disease. This can range from skin lesions such as moles and warts to brain lesions such as tumours. Finally, tumours are abnormal masses of tissue that can be either benign or malignant. Popular examples include breast cancer tumors and brain tumors

13. Exploring the Anatomy of Structures

Calling all curious learners who are interested in understanding the anatomy of structures! Explore the Skull, Chest Cavity, and Spine to satisfy your need for knowledge.

Learn the ins and outs of the Skeletal System by getting a closer look at these components. Start by delving into the Skull, the bony structure that houses and protects the brain – found in humans, cows, and other mammals. Then shift your focus to understanding the Chest Cavity and how it holds our most vital organs, like the heart and lungs. Finally, please take a look at the Spine, the column of bones that runs from head to toe and helps us stand and move.

Exploring Necrosis and Its Effects

It is typically termed cell death which happens when cells are injured, infected, or otherwise destroyed. Necrotic tissue can be identified by its discolouration and the presence of an inflammatory response in the surrounding area. It is important to understand necrosis and its effects, as it can lead to serious health complications if not treated properly.

The process of necrosis begins with cellular damage, which may occur due to physical trauma, radiation exposure, extreme temperatures, toxic chemicals, or infectious agents such as bacteria and viruses. When this damage occurs on a cellular level, enzymes are released from lysosomes within the cell, which causes further destruction of the cell’s structure and membrane integrity.

Understanding Inflammation and Its Impact

Inflammation is the body’s complicated biochemical response to injuries or illness. It is a natural process that aids in the body’s defence against external invaders such as germs and viruses while also mending damaged tissue. Inflammation can manifest itself in a variety of ways, ranging from modest redness and swelling to severe pain and fever.

While inflammation can be beneficial in some cases, it can also lead to chronic health problems if left unchecked. When inflammation becomes prolonged or excessive, it can damage healthy tissues and organs over time. This type of prolonged inflammation is known as chronic inflammation and may contribute to conditions like heart disease, diabetes, arthritis, asthma, and certain cancers.

Embracing the Unconventional: Understanding Abnormality

In a world where conformity is often expected, it can be challenging to understand and accept those who are considered “abnormal.” But what does it mean to be abnormal? Abnormality is defined as any behavior or condition that deviates from the norm. This could include physical disabilities, mental health issues, social anxieties, religious beliefs and practices, or having different interests than those around you.

When we think of abnormality in society today, there is an inherent stigma associated with it. People may fear the unknown or feel uncomfortable when confronted with something unfamiliar; this can lead them to judge others without understanding why someone might act differently than they do. So don’t assume that just because someone acts differently than you do means they’re wrong or bad!

Getting a Circular Look at Radial Angiography

Radial angiography is a medical imaging method that allows you to see the blood arteries in your body. It is commonly used to diagnose and treat coronary artery disease, aneurysms, and vascular malformations. Radial angiography utilizes X-ray images from different angles to create a circular view of the studied vessels. This allows doctors to get a better understanding of the anatomy and pathology of the vessels.

The process begins with an injection of contrast material into the patient’s bloodstream. This material helps to highlight any abnormalities or blockages that may be present in the vessels being studied. The patient is then placed in a special X-ray machine called a C-arm, which rotates around them while taking multiple images from different angles

18. Unlocking the Mysteries of a PET scan

Its full form is Positron Emission Tomography Scan. It is a powerful diagnostic tool used to detect and diagnose diseases in the body. It is a type of imaging test that uses a radioactive tracer to create detailed 3D images of the inside of the body. The tracer is injected into the patient’s bloodstream and then travels through the body. As it moves through organs and tissues, it emits signals detected by a special camera. This information is then used to create an image of the body’s internal structures.

PET scans help us diagnosing cancer, heart disease, brain disorders, and other conditions that affect organ function. They can also be used to monitor how well treatments for these conditions are working.

An Inside Look at Fluoroscopy

Fluoroscopy in medical imaging employs X-rays to provide real-time pictures of the body. It is used to diagnose and treat a variety of conditions, including cancer, heart disease, and gastrointestinal disorders. Fluoroscopy can also be used to guide minimally invasive procedures such as biopsies and catheterizations.

During a fluoroscopy procedure, the patient lies on an examination table while an X-ray machine passes radiation through the body. A detector plate detects the radiation and displays a picture on a monitor in real time. This allows the doctor to observe the movement of organs or other structures within the body

“The Not-so-Narrow Tunnel of Stenosis”

The study provides an in-depth look at the stenosis. Stenosis is a medical condition that occurs when a passageway or opening in the body narrows, such as the spinal canal or an artery. This narrowing can cause pressure on nerves and other structures, leading to pain and other symptoms. Many conditions, including age-related wear and tear of the spine, trauma, tumours, infection, and congenital abnormalities, can cause stenosis.

The most common type of stenosis is lumbar spinal stenosis (LSS). LSS occurs when the spinal canal narrows in the lower back area due to degenerative changes in the spine. This narrowing can pressure the nerves that travel through this area of the spine, causing pain and other symptoms.

A Cross-Sectional Guide to Imaging Speak

Cross-sectional imaging creates a three-dimensional (3D) representation of the body by combining several images obtained from different angles. It diagnoses and monitors diseases, injuries, and other conditions. Cross-sectional imaging can be used to detect tumours, cysts, fractures, and other abnormalities in the body.

When performing cross-sectional imaging, doctors will often use contrast agents such as barium or iodine to help enhance the visibility of certain areas on the scan. Contrast agents are injected into the patient’s bloodstream before scanning so they can be seen more clearly on the scan.

Bone Densitometry Classification System

Bone densitometry is a medical imaging technique used to measure the density of bones to diagnose and monitor bone diseases. The World Health Organization (WHO) Bone Densitometry Classification System is commonly used for classifying bone density. This approach was created in 1994 and has subsequently been recognized as the gold standard for measuring bone health by several nations.

The WHO Bone Densitometry Classification System uses a four-level scale to classify bone density. The first level, normal, indicates no signs of osteoporosis or other bone diseases. The second level, low-normal, suggests that there may be some signs of osteoporosis but not enough to warrant treatment. The third level, osteopenia, indicates an increased risk of developing osteoporosis and should be monitored closely. Finally, the fourth level, osteoporosis, indicates an advanced stage of bone loss and requires immediate treatment.

23. Unraveling the Mysteries of Computed Radiography

Computed radiography (CR) is a digital imaging technique that captures and stores X-ray images. It is an alternative to traditional film-based radiography, which uses photographic film to capture the image. CR technology has revolutionized the field of medical imaging, providing faster, more accurate results than ever before.

CR works by using a special phosphor plate that is exposed to X-rays. The plate absorbs the X-rays and stores them as an electrical charge. This charge is then scanned and turned into digital data, which may be displayed on a computer monitor or printed for further examination.

Unlocking the Potential of Intraoperative Radiography

Intraoperative radiography (IORT) is a relatively new imaging technique that has the ability to alter how surgeons approach their profession. This technology allows for real-time imaging during surgery, providing surgeons with unprecedented accuracy and precision. IORT can be used to detect small tumours or other abnormalities that may not be visible to the naked eye, allowing for more precise surgical interventions.

The use of IORT in surgery has been steadily increasing over the past few years as its advantages have become more widely known. It is particularly useful in orthopedic surgeries, where it can help guide the placement of screws and other implants.

Reimagining Radiography: The Power of Virtual Radiography

Virtual radiography (VR) uses computer-generated images to create detailed 3D models of the body. This allows doctors to quickly and accurately assess a patient’s condition without performing an invasive procedure or taking multiple X-rays. VR also eliminates the need for costly equipment, such as X-ray machines, which can be expensive to maintain and operate.

The use of virtual radiography has already been shown to improve accuracy and reduce costs in many areas of healthcare. For example, it has been used successfully in orthopedic surgery, where it can provide detailed images of bones and joints that are difficult to capture with traditional X-rays. It has also been used in cardiology, which can help identify blockages in arteries without requiring an invasive procedure.

A Scintillating Look at Scintigraphy

Scintigraphy is a type of imaging technique used to diagnose and monitor various medical conditions. It involves using a radioactive tracer, injected into the body and then detected by a special camera. The camera produces images that can be used to identify areas of abnormal activity in the body, such as tumours or infections.

Scintigraphy has been used for decades to diagnose and monitor diseases such as cancer, heart disease, kidney disease, and thyroid disorders. It can also be used to detect bone fractures or other injuries. In addition, scintigraphy can be used to evaluate organ function and detect abnormalities in blood flow.

The Science behind Doppler Flow Studies

Doppler flow studies are a type of medical imaging technique used to measure the speed and direction of blood flow in the body. This type of study is based on the Doppler Effect, which is an acoustic phenomenon that occurs when sound waves are reflected off moving objects. The Doppler Effect causes a change in the frequency of the sound waves, which can be detected by specialized equipment.

In medical imaging, Doppler flow studies use ultrasound technology to detect changes in blood flow. Ultrasound waves are sent into the body and bounce off red blood cells as they move through vessels. A transducer then picks up the reflected sound waves and converts them into electrical signals that a computer can analyse.

Examining the Impact of Nuclear Medicine Studies

Nuclear medicine studies are a sort of medical imaging that employs small quantities of radioactive material to diagnose and cure disorders. Nuclear medicine studies can provide valuable information about the functioning of the body’s organs, bones, and other tissues. They are used to detect cancer, heart disease, kidney disease, and other conditions.

The use of nuclear medicine studies has increased significantly over the past few decades due to technological advances and an increased understanding of their potential benefits. However, there is still some debate about whether they should be used more widely.

Take a Peek inside Apnea Imaging: A Visual Journey

Apnea imaging is a type of medical imaging that uses specialized techniques to visualize the airways and lungs. It is used to diagnose and monitor obstructive sleep apnea (OSA), a condition in which a person’s breathing stops and starts during sleep. Apnea imaging can be performed using X-rays, computed tomography (CT) scans, magnetic resonance imaging (MRI), or ultrasound.

X-Rays: X-rays are the most commonly used form of apnea imaging. They provide detailed images of the chest and lungs, allowing doctors to identify any blockages or abnormalities in the airway. X-rays are quick and easy to perform, but they provide less detail than other forms of apnea imaging.

Anatomical Orientation: Coronal, Sagittal, Transverse

Anatomical orientation is a term used to describe the three-dimensional orientation of body structures, organs, and tissues. Medical professionals need to understand anatomical orientation to diagnose and treat patients accurately. The three main orientations are coronal, sagittal, and transverse.

The coronal orientation is referred to as a plane that divides the body into anterior (front) and posterior (back) parts. This plane runs from side to side, perpendicular to the body’s long axis. In this orientation, structures are viewed as if looking at them from the front or back.

Sagittal orientation describes a plane that divides the body into left and right halves. This plane runs from head to toe along the body’s long axis. In this orientation, structures are viewed as if looking at them from the side.

Transverse orientation describes a plane that divides the body into upper and lower sections. This plane runs across the body’s width, perpendicular to both coronal and sagittal planes. In this orientation, structures are viewed as if looking at them from above or below.

Seeing Through the Mysteries of Radiopaque Materials

Radiopaque materials are substances that can be seen on X-ray imaging. These materials are used in a variety of medical and industrial applications, from diagnosing medical conditions to inspecting the integrity of pipelines. Radiopaque materials have unique properties that make them invaluable for these purposes, but what exactly makes them so special?

At its most basic level, radiopacity is the ability of a material to absorb X-rays and appear opaque on an X-ray image. The atomic structure of the material determines this property; some elements are naturally more radiopaque than others. For example, iodine is one of the most radiopaque elements, while carbon is relatively transparent to X-rays.

The most common type of radiopaque material used in medical imaging is barium sulfate. Barium sulfate has a high atomic number and therefore absorbs X-rays very well.

Exploring Paracentric Radiation Therapy

Paracentric radiation therapy is a type of external beam radiation therapy used to treat cancer. It is a specialized form of radiotherapy that uses multiple beams of radiation from different angles to target the tumour while sparing surrounding healthy tissue. This technique has been used for many years in treating various types of cancer, including prostate, breast, lung, and head and neck cancers.

The paracentric approach utilizes several beams of radiation focused on the tumour from different angles. This allows for more precise tumour targeting while minimizing damage to nearby healthy tissue. The beams can be directed to varying depths within the body, allowing for more effective treatment of tumours located deep within the body.

Achieving Optimal Clarity with Isotropic Resolution

Isotropic resolution refers to the ability of an imaging system to capture images with equal resolution in all directions. This means that the image will have the same level of detail regardless of the orientation or angle from which it is viewed.

The most common way to achieve isotropic resolution is through the use of multiple cameras, each capturing a different angle of view. By combining these images, a single image can be created that has equal detail in all directions. This technique is often used in medical imaging, allowing doctors tto understand better what they are looking at and make more accurate diagnoses.

Taking a Closer Look at the Future of Tomosynthesis Scanning

Tomosynthesis scanning is a revolutionary imaging technique that has the potential to revolutionize medical diagnosis. This technology uses X-ray beams to create three-dimensional images of the body, allowing doctors to see more detail than ever before. Tomosynthesis scanning has already been used in mammography and is now being explored for use in other areas of medicine, such as orthopedics and cardiology.

Tomosynthesis scanning can also be used to detect diseases or conditions that may not appear on traditional X-rays. For example, tomosynthesis scans can detect small lesions or calcifications that may indicate breast cancer before they become visible on standard mammograms.

Multiplanar Imaging: An Innovative Take on Diagnostics

Multiplanar imaging is an innovative approach to medical diagnostics that has revolutionized the way doctors and radiologists view and interpret images of the body. This technique combines multiple imaging modalities, such as MRI, CT, and ultrasound, to create a three-dimensional (3D) representation of the body’s anatomy. It allows for more accurate diagnosis and treatment planning by providing a comprehensive view of the patient’s condition.

The multiplanar imaging technique was first developed in the early 2000s to improve diagnostic accuracy and reduce radiation exposure. Multiplanar imaging is beneficial for diagnosing complex conditions such as cancer or heart disease. For example, it can help doctors determine if a tumour is malignant or benign by providing detailed information about its size, shape, and location within the body.

Getting Radial: A Guide to Mastering Imaging Algorithms

Radial imaging algorithms are a powerful tool for medical professionals, allowing them to quickly and accurately diagnose a wide range of conditions. Radial imaging algorithms use mathematical equations to create images from data collected by medical devices such as MRI scanners or ultrasound machines. These images can then be used to diagnose diseases, detect abnormalities, and monitor the progress of treatments.

Radial imaging algorithms are based on the concept of “radial symmetry” – the idea that an object can be rotated around its center point without changing its shape or size. This allows medical professionals to take multiple images from different angles and combine them into one image that shows the entire object in detail. This is especially useful for diagnosing complex conditions such as tumors or heart defects, where multiple angles may be needed to get an accurate picture.

Getting to the Core of Molecular Imaging

Molecular imaging is a rapidly growing field of medical science that has the potential to revolutionize the way we diagnose and treat diseases. Molecular imaging is a type of imaging technology that uses specialized techniques to visualize and measure molecular processes in living organisms. It is used to detect and monitor changes in biological systems at the molecular level, allowing for more accurate diagnosis and treatment of diseases.

Molecular imaging can study various biological processes, such as gene expression, protein synthesis, cell metabolism, and drug delivery. It can also be used to detect changes in tissue structure or function due to disease or injury. By providing detailed information about the underlying biology of a disease, molecular imaging can help physicians make more informed decisions about diagnosis and treatment.

Exploring the Potential of Teleradiology Systems

Teleradiology systems are becoming increasingly popular in the medical field as they offer several advantages over traditional radiology services. Teleradiology is the practice of sending images and other medical data from one location to another via electronic means. This technology has revolutionized how radiologists can care for patients, allowing them to access imaging studies from any location with an internet connection.

Additionally, teleradiology systems allow for faster diagnosis and treatment decisions due to their ability to transmit images quickly between multiple locations. This can be especially beneficial in emergencies where time is of the essence.

Computer Assisted Diagnosis (CAD) in Radiology

Computer Assisted Diagnosis (CAD) in radiology is a rapidly growing field of medical imaging technology. It involves using computer algorithms to analyze medical images and provide diagnostic information to radiologists. CAD systems are designed to detect abnormalities in medical images, such as tumours or lesions, and can be used to assist radiologists in making more accurate diagnoses.

Advances in computer technology and artificial intelligence have fueled the development of CAD systems (AI). AI algorithms are used to analyze medical images and identify patterns that may indicate an abnormality. These algorithms can also be trained on large datasets of medical images to improve their accuracy over time.

Exploring New Radio-Pharmaceutical Drugs to Improve Care

The development of new radio-pharmaceutical drugs has been a major focus of medical research in recent years. Radio-pharmaceutical drugs are pharmaceuticals that contain radioactive elements, which allow them to be used for diagnostic and therapeutic purposes. These drugs can be used to diagnose diseases such as cancer, heart disease, and neurological disorders and treat certain conditions.

Radiopharmaceuticals have the potential to transform healthcare delivery by enabling more accurate diagnostic and treatment choices. For example, they can be used to detect cancer at an earlier stage than traditional imaging techniques, allowing for earlier intervention and improved outcomes. They can also target specific body areas with radiation therapy or chemotherapy, reducing side effects and improving patient comfort.

Developing Protocols for Diagnostic Procedures and Interventions

Interoperability solutions for radiology involve the use of standards-based protocols and technologies to enable the sharing of medical images, patient records, and other data between different systems. This includes both hardware and software components, such as image viewers, digital archiving systems, and communication networks. Using these solutions, radiologists can access patient information from any location to make informed decisions about diagnosis and treatment.

One example of an interoperability solution for radiology is the Digital Imaging Network Architecture (DINA). DINA is a set of standards developed by the American College of Radiology (ACR) that enables the secure exchange of medical images between different systems. It also supports various imaging modalities, including X-rays, CT scans, MRI scans, ultrasound, PET scans, and nuclear medicine scans.

42. Spectroscopy: An Introduction to the Science of Spectra

Spectroscopy is a powerful analytical technique used to identify and quantify the chemical composition of a sample. It works by measuring the interaction between electromagnetic radiation and matter, which can be used to determine the structure, composition, and physical properties of a material. Spectroscopy is widely used in many fields, such as chemistry, physics, astronomy, medicine, and engineering.

Spectroscopy involves the use of light or other forms of electromagnetic radiation to measure the energy levels of atoms or molecules in a sample. This information can then be used to determine the chemical composition and structure of the sample. The type of spectroscopic technique used depends on the type of radiation being measured (e.g., visible light, infrared light, ultraviolet light) and what kind of information is desired from the sample (e.g., molecular structure or elemental composition).

43. Nomenclature of X-Ray Imaging Tracers

X-ray imaging tracers are substances used to visualize and diagnose medical conditions. They are usually given intravenously and identified using X-ray imaging techniques like computed tomography (CT) or fluoroscopy. The nomenclature of these tracers is important for accurate diagnosis and treatment.

Tracer nomenclature is based on the type of atom that is being imaged. For example, an “iodine” tracer would contain iodine atoms, while a “barium” tracer would contain barium atoms. Other common elements in X-ray imaging tracers include gadolinium, technetium, and thallium.

The name of the tracer also includes information about its chemical structure. For example, a “diethylenetriaminepentaacetic acid” (DTPA) tracer contains five carboxylic acid groups attached to an amine group. This type of tracer is often used to image kidney function because it binds strongly to certain metals in the body, such as calcium and iron.

44. Exploring Effective Radiation Therapy Processes

Radiation therapy is a type of cancer treatment in which high-energy radiation is used to destroy cancer cells. It is a successful treatment for many forms of cancer, and it can be used alone or in conjunction with other therapies, including surgery and chemotherapy. The radiation therapy process involves several steps, from the initial consultation to the completion of treatment.

Consultation with a radiation oncologist is the first step, who will assess the patient’s condition and determine if radiation therapy is an appropriate treatment option. During this consultation, the doctor will discuss the risks and benefits of radiation therapy and any potential side effects.

The next step in the process is a simulation, which helps create a 3D image of the tumor so doctors can accurately target it with radiation beams during treatment. During simulation, patients are asked to lie still on a table while images are taken from multiple angles using X-rays or CT scans. This information is then used to create a 3D model of the tumor so that doctors can precisely direct radiation beams at it during treatment sessions.

Once the simulation has been completed, patients begin their actual course of radiation therapy treatments. These treatments typically last between 10-30 minutes each day for several weeks, depending on the type and severity of the cancer being treated. During each session, patients lie still on a table. At the same time, beams of high-energy X-rays are directed at them from multiple angles using sophisticated machines called linear accelerators (or LINACs).

Introduction

Citation distributions are extremely skewed. Most scientific papers are seldom cited, if ever, in the subsequent scientific literature while some papers receive an unusually high citation counts [ 1 ]. In the past decade, there has been a growing interest in using highly cited papers as indicators in research assessments. There may be two reasons for this tendency. First, the increasing focus on scientific excellence in science policy in the context of the enormous quantities of scientific outputs makes it imperative to screen out the most successful or influential work. “Many countries are moving towards research policies that emphasize excellence; consequently; they develop evaluation systems to identify universities, research groups, and researchers that can be said to be “excellent” [ 2 ]. Second, for visibility issues, academic professionals are consistently interested in pursuing high citations for their own work and also tend to follow the research with higher citations. In this way, they can stay current regarding research trends and make informed decisions on potential research topics. High citations imply more visibility, generally accompanied by more supports from public or private funders. Therefore, scientific researchers will be very much proud if their publications are selected as highly cited papers (HCPs).

Incites Essential Science Indicators (ESI), an analytic tool provided by Clarivate Analytics for identifying the top-charting research in Web of Science (WoS)-indexed journals, is widely used to evaluate HCPs, providing information such as the countries/regions [ 3 , 4 ], institutes [ 5 ], and researchers [ 6 ], etc. ESI-HCPs, representing the top 1% in each of the 22 ESI subject fields, vary by fields and by years in a 10 years’ rolling. A paper is selected as a HCP only if its citation count exceeds the 1% citation threshold of the corresponding research fields and publication year.

Over recent years, a number of studies have been conducted on HCPs based on data from ESI [ 7 , 8 , 9 ]. For example, Ioannidis Boyack et al. surveyed the most-cited authors of biomedical research for their views on their own influential published work [ 9 ]. Aksnes found that HCPs are typically authored by a large number of scientists, often involving international collaboration [ 10 ]. Some studies even try to predict the HCPs by mathematical models [ 11 ], implying “the first mover advantage in scientific publication” [ 12 , 13 ]. That is, the first papers in a field will, essentially regardless of content, receive citations at a rate enormously higher than papers published later.

Bibliometrics, a term coined by Pritchard A [ 14 ], is a statistical method used to evaluate scientific development, determine research impacts, compare research performance and identify emerging fronts [ 15 , 16 ]. There have been many bibliometric studies on natural science or social science as a general field [ 17 , 18 ]. There have also been a few subject-specific ones on computer science [ 19 , 20 ], on applied linguistics [ 21 ], and on operations research and management Science [ 22 ]. In this regard, bibliometrics has been applied to summarize the development of a specific subject, generating valuable information such as the most cited publications/journals and the most frequently explored topics, etc. Such information is of great importance and interest to researchers as well as academic institutions and government/private agencies in making funding and science policy decisions. However, to our knowledge, there has not been one bibliometric study on the specific subject “ Radiology, Nuclear Medicine & Medical Imaging ” (RNMI) , a subject that covers resources on radiation research in biology and biophysics. Of the five broad research areas ( Arts & Humanities, Life Sciences & Biomedicine, Physical Sciences, Social Sciences, technology ) in Web of Science database, Life Sciences & Biomedicine has the most number of subject categorizations (76 in total), implying the complexity and richness as well as importance of this research line. As an important subject area in Life Sciences & Biomedicin e in response to the rapidly evolving healthcare industry, the research productivity in this RNMI has been tremendous. A thorough investigation of the existing literature especially the HCPs will help keep researchers informed about the state of the arts and research trends in this subject.

The purpose of this study is to spotlight the trends and hot topics in the subject category of Radiology, Nuclear Medicine & Medical Imaging with the bibliometric analysis of highly cited papers to help researchers get the most updated information in the future study.

A bibliometric approach was used in the present study to map the HCPs in RNMI in WoS. As one of the biggest bibliometric databases, WoS is the most frequently used database in bibliometric studies [ 23 ]. The methods for data retrieval are described as follows.

We searched in WoS Core Collection at the portal of the University library. We filtered the results by clicking the “ Highly Cited in Field ” trophy icon. We then downloaded all the bibliometric data for further analysis including publication years, authors and affiliations, publication titles, countries/regions, organizations, abstracts, citation reports, etc. After the removal of the publications with incomplete bibliometric information, a total of 1325 HCPs were harvested. The yearly publication distributions of the 1325 HCPs were shown in Figure S1 (Online Resource 1). The data retrieval was completed on 15 December, 2021. We collected the impact factor (IF) of each journal from the 2021 Journal Citation Reports (JCR).Table 1 shows the strategies of the retrieval queries.

Three points are to be mentioned here. First, the WoS Core Collection was searched because it boasts as an important bibliometric database which includes literature and citation information indexed in SCIE, SSCI and A&HCI. More importantly, it has been widely used in bibliometric analysis of previous studies both in natural sciences [ 24 , 25 ] and in social sciences [ 21 , 26 ]. Because RNMI belongs to the natural sciences, we restrict the index in SCI-expanded to retrieve the relevant data. Second, only articles and reviews are considered in HCPs selection. There is no need to restrict the document types in our search. Third, the dataset of ESI-HCPs is automatically updated every 2 months to include the most recent 10 years of publications. Therefore, only the papers in the recent decade will be counted as HCPs. There is no need to set the date range.

To identify the most influential papers, we ranked all the HCPs by the Relative Citation Rate (RCR), a new metric that uses citation rates to measure influence at the paper level [ 27 ]. Since the citation count a paper receives is closely associated with the number of years it is published, it is invalid to rank paper impact solely on Raw Citations (RC). Therefore, RCR, recently endorsed by the National Institutes of Health, has been employed here to pinpoint the most highly cited papers. RCR is based on weighting the number of citations a paper receives to a comparison group within the same field [ 28 ]. The icite tool is used here to generate RCR metrics for all the HCPs ( https://icite.od.nih.gov/ ).

Word frequency analysis based on corpus is a bibliometric method to identify hotspots and developmental trend of one domain. In this study, we built an Abstract corpus with all the abstracts of the HCPs. The n -grams (2–4) in the corpus were retrieved and analyzed to detect the most frequently researched topics in the HCPs. The procedures to retrieve the n-grams were described as follows. First, the abstracts of all the 1325 HCPs from the downloaded bibliometric data were saved in separate files in txt. Formats in one folder to create a mini abstract corpus with a total of 299,810 tokens. Second, Anthony’s AntConc, a freeware corpus analysis toolkit for concordancing and text analysis, was used to extract n-grams that include clusters of two to four continuous words [ 29 ]. AntConc is widely used in previous studies [ 16 , 21 , 26 ]. It automatically ranks all the retrieved n-grams in decreasing order. We also generated a list of individual nouns in case of missing some important topics. The reason to exclude the pronouns, modals and many other functional words is that research topics are usually phrases that do not contain these functional words. For topic candidacy, we adopt both frequency (10) and range criteria (10). That is, a candidate n-gram has to appear at least ten times and in at least ten different abstracts for further consideration. The frequency threshold ensures the significance of the candidate topics while the range threshold ensures the topics are not overly clustered in a limited number of papers. In this process, we actually tested the frequency and range thresholds several rounds for the inclusion of all the potential topics. In total, we got 521 nouns, 205 2 g, 39 3 g, and 5 4 g. Third, concerning the list of n-grams and monograms (nouns here), the authors discussed extensively to decide which should be taken as the potential research topics until full agreements were reached.

Besides the word frequency analysis based on the Abstract corpus, we performed knowledge mapping (i.e., network analysis) using VOSviewer ( www.vosviewer.com ), in which we focused on the network and “link strength” between author keywords. Knowledge mapping can be employed to map the scope and structure of the discipline while revealing key research clusters [ 30 ]. Since fractional counting approach assigns co-authored publications fractionally to each author, proper field-normalized results can be obtained [ 31 ]. Therefore, we used fractional counting in our analysis. This process produced the co-occurrence network of the most frequently used author keywords. Knowledge mapping of the author keywords was an important addition to the corpus based investigation of the abstracts.

Main publication venues of HCPs

The top 20 journals with more than 17 HCPs published are listed in Table 2 . They contributed around 80% of the total HCPs (1039/1325). The highest contribution comes from Neuroimage (207) , followed by Radiology (159) . They are also the only 2 journals with more than 100 HCPs, accounting for almost 30% of the total number of the HCPs, overwhelmingly exceeding the others on the list. As the only Q2 journal (between top 50% and top 25%) among the top five (the other four in the Q1, top 25%) by the Journal Citation Reports (JCR) quantile rankings, Neuroimage tops the list with certain surprise.

Because the total number of papers published in each journal varies greatly per year and the HCPs are also connected with journal circulations, we divide the total number of papers (TP) in the examined years (2011–2021) with the number of the HCPs to acquire the HCP percentage for each journal (HCPs/TP). As we can see, the top six journals with the highest percentage of the HCPs are Med Image Anal (2.91), IEEE T Med Imaging (2.83) , Radiology (2.67) , Neuroimage (1.91) , J Cardiovasc Magn Reson (1.91), JACC-Cardiovasc Imag (1.75). That implies that papers published in these journals have a higher probability to enter the HCPs list. In terms of the latest journal impact factor (IF) in 2021, the top five journals with the highest IF are JACC-Cardiovasc Imag (14.805), Radiology (11.105), J Nucl Med (10.057), IEEE T Med Imaging (10.048) and Eur J Nucl Med Mol I (9.236) . The number of the HCPs in these journals take up a large share of the total HCPs (over 30%), implying a close relationship between the journal IF and the number of the HCPs in the journal.

Countries distribution

The top 16 productive countries with more than 50 HCPs are presented in Fig. 1 . The USA took the lead with 707 HCPs (53.358%), confirming its leading position as a traditional scientific powerhouse in this subject, followed by Germany (20.302%) and England (19.623%). It is to be mentioned that only three Asian countries enter the top 16 list ( China, South Korea, Japan ). China even boasts the fourth position with 196 HCPs (14.792%). However, scholars from outside the traditional publishing countries need to be more visible for their work in RNMI.

Top 16 countries/regions with the most HCPs

Most influential papers by RCR

During the data processing, we found that the papers on COVID-19 published in the year of 2020 had extremely high RCR compared to papers on other subjects. As an unexpected global epidemic starting in late 2019, COVID-19 ignited research interests from all over the world especially in China where the epidemic was first reported. Many papers got quickly published and cited during this period in response to the urgent needs to find treatments. If we mix the papers, paying no attention to this public health incident, the COVID-19-related papers will take up 75% of the top 20 highly cited papers in terms of RCR (15/20), which was unfair for other non-COVID-19-related papers because of the distorted impact image. Therefore, we produced two lists of ranking: one for the non-COVID-19 papers in Table 3 and one for the COVID-19 papers in Table 4 . The yearly citation trends of each listed HCP can be seen in Figure S2 (Online Resource 2).

Table 3 shows some interesting patterns. First, 9 out of the top 20 HCPs were published in Neuroimage , which helps corroborate the findings on the main publication venues. Second, in terms of the document types, reviews (11) slightly outnumber articles (9), which may imply that reviews share the same amount of citation opportunities as the articles in the field of medical studies if not more. Third, three types of research orientations can be discerned from the top 20 HCPs: recommendations or guidelines (#1, 6, 11, 16, 18, 19); processing software (#2, 7, 9); analysis methods (#4, 5, 8, 12, 13, 15, 17, etc.).

The top ten highly cited papers on COVID-19 shows a different picture in Table 4 . 9 out of the top ten HCPs were published in Radiology , which once again testifies its popularity and importance in the field of RNMI . Ai tao ’s (2020) Correlation of Chest CT and …tops the list with RCR at 703.55, three times more than Roberto M Lang (2015) with RCR at 203.92, which shows the enormous attention paid to this unprecedented epidemic outbreak.

Most frequently explored topics

Table 5 presents the top 33 research topics above the observed frequency of 38. The observed frequency count for each topic in the abstract corpus is included in the brackets. Topics such as magnetic resonance imaging (325), deep learning (191), prostate cancer (162), chest CT (145), computed tomography (141), CT images (121), PSMA PET (119), coronavirus disease (115), convolutional neural network(s) (108) and FDG PET (100) were the top ten most frequently mentioned topics based on the corpus analysis of the abstracts. We grouped the topics into five broad categories, including devices, organs, artificial intelligence (AI), images, and others, according to topic relationships.

The first group is mainly about the imaging devices in the RNMI field including MRI (396) , CT (484) and PET (279) .

The second group concerns the human organs such as brains (250), prostate (162), heart (160), lungs (153), and breast (93) . Cancer-related phrases (prostate cancer, and breast cancer) were among the top list in frequency. For the brain, topics such as functional connectivity and white matter were more mentioned.

The third group are all related to AI technology ( artificial intelligence, deep learning, machine learning, convolutional neural networks, etc.).

The fourth group is about image information. Image quality is an important focus in MR/CT/PET scanning because it determines whether the images can been used or not. Imaging features can provide more information and are widely used in AI.

Topics in the last group constitute the core concepts in radiology. Radiation therapy is the most important treatment method for cancers. Especially when combined with MRI and CT, precise radiotherapy will be a promising alternative for cancer treatment in the future. As the method for assessing diagnosis performance of quantitative parameters, receiver operating characteristic (ROC) is also the main technology. Contrast agents is the important part of CT and MRI scans. Polymerase chain reaction is the gold standard in the detection COVID-19. It is no wonder that these topics enter the hot topic list because they are closely connected to the topics in other categories.

Author keywords analysis

A total of 2796 keywords were retrieved. We set the minimum number of occurrences of a keyword at 5. Then, 131 keywords meet the threshold. For each of the 131 keywords, the total strength of the co-occurrence links with other keywords were calculated. The top 15 keywords with the greatest total link strength were shown in decreasing order in Table 6 . VOSviewer classified the 131 keywords into 9 clusters, as shown in Fig. 2 . The link strengths for deep learning, covid-19, mri, machine learning, prostate cancer, computed tomography were 79, 74, 42, 40, 39, 39, respectively. The thickness of the lines which was determined by the frequency of the keywords in HCPs shows the link strength between the keywords.

The co-occurrence of author’s keywords

A comparison between the word frequency analysis of the Abstract corpus and the knowledge mapping of the author keywords shows similar research activities, which can be evidenced by the overlapping of the high frequent topics and the author keywords. These hot terms not only reflects the important research trends up to now, but also points the direction for future research in RNMI. For example, AI is gaining increasing popularity in the healthcare industry especially in handling a huge amount of patient data and recognizing complex disease patterns. In the future, AI-based technology is bound to unfold more hidden information from big data and inform healthcare policymakers and clinicians in making effective clinical decisions. Besides, considering the complex functioning of the human brain, the research is multidisciplinary in nature. Therefore, a collaboration across scientific disciplines will better reveal the intricacies of the human brains.

To our knowledge, this is the first comprehensive bibliometric study of Highly Cited Papers (HCPs) in the subject category of RNMI across the years spanning from 2011 to 2021. The results showed that Neuroimage, Radiology, IEEE T Med Imaging, J Nucl Med had the largest number of HCPs published, accounting for about 40% of the total 1325 HCPs. The traditional academic powerhouses in RNMI such as the USA, Germany and England are leading the publications while countries such as China and Italy are catching up. For the top 20 non-COVID-19 HCPs, 3 types of research orientations can be detected: recommendations or guidelines; processing soft wares; analysis methods . Reviews slightly outnumber articles in terms of document types. Among the top ten COVID-19 HCPs published in the year 2020, nine were published in Radiology, and chest CT was the most frequent used term in the paper titles.

It is interesting to find Neuroimage, the only Q2 journal in the top five, tops the list with the most HCPs. Research on human brains is increasing rapidly since the initiation of the WU-Minn Human Connectome Project in America in September 2010, aiming to map macroscopic human brain circuits and their relationship to behavior[ 32 ]. Many countries/regions follow the lead by starting their own brain projects, such as Human Brain Project in European Union, Brain/Minds in Japan, and Brain Science and Brain-Like Intelligence Technology in China. Therefore, topics such as functional connectivity, white matter, brain regions can be found (Table 5 ), reflecting the scientific enthusiasm in human brains. The surging research interest in brain functioning in the last decade across the globe stimulated more papers in related journals such as Neuroimage , especially after the initiation of the WU-Minn Human Connectome Project in September 2010. Besides, from January 2020, Neuroimage is an open access journal. Authors who publish in Neuroimage can make their work visible immediately, which might encourage more authors to contribute their work. It can be evidenced by more publications in Neuroimage in 2020 compared to those in previous years.

United States, Germany and England are undoubtedly the most impactful in the research area of RNMI. Historically, western countries, especially the United States, have been at the center of academic publishing, supported by huge investments in scholarly research and technical infrastructure. Besides, because the research in RNMI usually involves highly priced facilities such as MRI scanner, the developed countries with more resources clearly stand in a more advantageous position in research and publishing. It should be noted here that a HCP is usually the joint writing of multiple authors from different institutions and/or countries[ 10 ]. Web of Science will generate all the bibliometric information of the papers, not restricted to the information about the first author or the corresponding author. In other words, all the countries and institutions listed on the HCPs will be treated evenly. In this way, a clearer picture about the HCPs distribution across countries can be painted.

Scientific research has always been driven by practical needs. It comes with no surprise that Roberto M Lang ’s (2015) Recommendations for cardiac chamber quantification [ 33 ] … tops the list with RCR at 203.92. The quantification of cardiac chamber size and function is the cornerstone of cardiac imaging. Jointly written by the American Society of Echo cardiography and the European Association of Cardiovascular Imaging , Roberto M Lang ’s (2015) is the updated recommendations for cardiac chamber quantification that guide the echo cardiographic practice with sweeping popularity. Because COVID-19 was first reported in China, most of the studies during this period were conducted in hospitals or universities in China, which can be easily seen from the top ten HCPs list. Sana Salehi’s (2020) Coronavirus Disease 2019 (COVID-19)… stands as the only HCP among the top ten beyond China (in USA). From the titles, Chest CT emerges as one of the hottest phrases. The fact that most patients infected with COVID-19 had pneumonia and characteristic CT imaging patterns helps explain its frequent use.

A great overlap between the most frequently explored topics and author keywords is identified. The hot topics can be generally grouped into five broad categories: devices, organs, artificial intelligence (AI), images, and others . MRI is the most frequently mentioned phrase. Compared to CT which only shows signal attenuation and has ionizing radiation, MRI can obtain the multi-contract images without ionizing radiation, and is widely used in whole human bodies except the lung. Especially, in the human brain projects, MRI is the main device. However, CT showed greater values in the lung disease than MRI, which can be evidenced by frequent use of CT in the COVID-19 publications. The use of PET (positron emission tomography) scan along with CT in clinical practice increases side by side with publications in this regard which can be seen in such frequent topics as PET CT, PSMA PET, FDG PET . Moreover, the clinical value of PET with MR is also increasing proven. In the future, PET will be an important device in the field of nuclear medicine and radiology.

Besides brain, lung, prostate, heart, and breast are the most concerned organ. According to the World Health Statistics released in 2020, an estimated 41 million people worldwide died of NCDs (noncommunicable diseases) in 2016, equivalent to 71% of all deaths. Four NCDs caused most of those deaths: cardiovascular diseases (17.9 million deaths), cancer (9.0 million deaths), and chronic respiratory diseases (3.8 million deaths), and diabetes (1.6 million deaths) ( World health statistics 2020: monitoring health for the SDGs, sustainable development goals. Geneva: World Health Organization; 2020. ). Of different cancer types, breast cancer, lung cancer, and prostate cancer were the top three most prevalent cancers, according to the latest GLOBOCAN2020 report by the International Agency of Research on Cancer, part of World Health Organization.

In recent years, AI has been a hot theme of modern technology and is creeping into almost every facet of modern life including medical research. Up to now, AI has been actively used in medical images recognition, medical intelligent decision-making, medical intelligent voice, and “Internet plus” medical treatment. As one of the first specialty in healthcare to adopt digital technology, radiology is well positioned to deploy AI for diagnostics due to digital images [ 34 ]. Gulshan first reported that AI could automated detected diabetic retinopathy and diabetic macular edema from over 100 thousand retinal fundus photographs, with high sensitivity and specificity [ 35 ]. In 2017, Golden reported that AI can quickly read photos to diagnose breast cancer with lymph mode metastases, greatly improving the speed of diagnosis [ 36 ]. AI also played an important role in detecting COVID-19 [ 37 , 38 , 39 ]. In the future, AI is bound to exert greater influence on the medical field. For example, AI shows great promise in changing treatment models, promoting medicine development, reshaping the medical industry, and even impacting the career paths of the medical practitioners. It is believed that artificial intelligence will bring profound changes to future medical technology and will be a powerful driving force for future medical innovation and reform.

There are several points to be mentioned here as for the most frequently explored topics. Decisions regarding the candidate topics were not easy and involved subjectivity. It was the results of several rounds of discussions from multiple professionals. Some n-grams are discarded because they are too general or not meaningful topics in RNMI. For example, quantitative analysis, high sensitivity, imaging technique and medical image are too general to be included. By meaningful topics, we mean the n-grams can help journal editors and readers to quickly locate their interested fields, as the author keywords such as brain networks, MRI imaging, CT scans. Besides, the examination of the limited 3/4-g and monograms (nouns) revealed that most of them were either not meaningful topics such as cancer detection rate and patients with prostate cancer or they were topics already identified in the 2 g such as weighted MR imaging in MR imaging. Therefore, the final list is mostly 2-g topics.

It should be noted that large numbers of quantitative data have been used here to map the HCPs from different perspectives. Despite the quantitative nature, our study also involves qualitative analysis and hence subjectivity, especially concerning what constitutes the research topics and topic categorization. Given the rapid developments in RNMI, more bibliometric research is needed in the future to help test and enhance the validity and reliability of this research approach and to help keep us accurately informed about the trends in RNMI.

Our study also has some limitations. The subject category of Radiology, Nuclear Medicine & Medical Imaging listed in WoS Categories needs to be further broken down into subcategories and subjects in future analysis. A finer granular subject classification of the research area would have painted a more detailed picture. In additional, the study focuses on the apex of the publishing pyramid in RNMI, the HCPs. And the bibliometric indexes here are all based on the WoS SCI international journals. Although these are the most celebrated and accessible works, some other publications of similar importance or highly localized publications which do not have the chance to enter the list and are not indexed in WoS are not given due attention in our study. This less widely cited research is a rich vein for future study. At last, the study seems to show that the number of citations a review paper receives is higher than that of an original article in RNMI. Therefore, it might be more useful to distinguish the two types of papers in future method design.

In conclusion, our results of the bibliometric analysis provided the updated trends and hot topics in RNMI. And the practitioners and researchers in RNMI can be better aided to locate the relevant literature and keep informed about the hot topics.

Radiology test can be used to diagnose immune checkpoint inhibitor-associated acute kidney injury

by Brigham and Women’s Hospital

Immune checkpoint inhibitors (ICIs) are a class of immunotherapy that have revolutionized the treatment of cancer. However, they can cause a wide variety of autoimmune toxicities, including immune checkpoint inhibitor-associated acute kidney injury (ICI-AKI).

Differentiating ICI-AKI from acute kidney injury (AKI) due to alternative causes, which are common in cancer patients , is challenging without a kidney biopsy due to the risk of bleeding for some patients.

In a study published in Journal of Clinical Investigation , researchers examined whether F 18 -FDG PET-CTs, a type of nuclear imaging study, could be used to distinguish patients with ICI-AKI from those with AKI from alternative causes.

They found that patients with ICI-AKI had much higher levels of radioactively-labeled glucose in the kidneys, indicating kidney inflammation, compared to patients with AKI from non-ICI causes. These findings indicate that this type of radiographic scan could be a non-invasive alternative to kidney biopsy for diagnosing ICI-AKI.

Previous research has demonstrated that the most common finding from kidney biopsies in patients with ICI-AKI is acute interstitial nephritis, or inflammation in the kidney as a result of activated T-cells. To diagnose this condition in current practice, patients must undergo a kidney biopsy.

However, patients may have contraindications (e.g., they may have only one kidney or they may be receiving treatment with blood thinners ), preventing them from proceeding safely with a kidney biopsy. Thus, non-invasive markers are greatly needed to diagnose ICI-AKI.

Case reports and smaller studies had explored the utility of F 18 -FDG PET-CT scans as a non-invasive option for diagnosing ICI-AKI, but those studies had significant limitations, including small sample size , lack of clear inclusion and exclusion criteria, and lack of a control group.

In this study, the team sought to address these limitations and investigate the utility of F 18 -FDG PET-CTs as a way to non-invasively diagnose ICI-AKI.

Using data from a previous multi-center study of patients with ICI-AKI, the study focused on those who had a F 18 -FDG PET-CT scan around the time of ICI-AKI diagnosis.

The study included two control groups: patients with AKI from non-ICI etiologies and patients treated with ICIs who did not have AKI at the time of a follow-up F 18 -FDG PET-CT. For all three groups, patients were included if they had F 18 -FDG PET-CTs scans at baseline and within 14 days of AKI onset (or, for the second control group, a follow-up scan between 90–365 days following ICI initiation).

Nuclear radiologists reviewed the F 18 -FDG PET-CTs at baseline and follow-up and recorded the average radiotracer standardized uptake value (SUV) in the renal cortices. The SUV quantifies the amount of radioactively-labeled glucose in the kidneys, serving as a marker of the amount of inflammation and metabolic activity occurring in the kidneys.

The team then calculated the average percent change in SUV from baseline to follow-up for each patient. The SUV mean increased by a median of 57.4% from baseline to follow-up among patients with ICI-AKI, whereas it only increased by 8.5% among patients with AKI from non-ICI causes and was unchanged in patients receiving ICIs without AKI.

The findings suggest that F 18 -FDG PET-CTs may be a useful test for diagnosing ICI-AKI.

The team's hope is to offer patients who can't undergo a kidney biopsy safely a non-invasive testing option, such as with F 18 -FDG PET-CTs scans, to differentiate the cause of AKI as being ICI-related vs. non-ICI-related. This has important implications for patients, because those with ICI-AKI are treated promptly with steroids, and their ICI therapy is typically held until their AKI has recovered or at least stabilized.

The next step is to validate these findings in a larger prospective study where the investigators recruit patients who have AKI while on ICI treatment to see if F 18 -FDG PET-CTs can definitively differentiate ICI-AKI from AKI from non-ICI causes.
