Korean Journal of Radiology

Top Research Topics at Korean Journal of Radiology?

The journal was organized to reinforce research efforts on Radiology, Magnetic resonance imaging, Nuclear medicine, Surgery and Internal medicine. Issues in Radiology were discussed, taking into consideration concepts from other disciplines like Lesion and Pathology. Mr imaging is a major topic of Magnetic resonance imaging research presented in it.

The research on Nuclear medicine featured in it combines topics in other fields like Diffusion MRI and Receiver operating characteristic. Korean Journal of Radiology links adjacent topics like Diffusion MRI with Effective diffusion coefficient. Topics like Percutaneous, Stent and Embolization are tackled as part of the discussions on Surgery.

In Korean Journal of Radiology, Gastroenterology, Oncology and Cardiology are investigated in conjunction with one another to address concerns in Internal medicine research.

• Receiver operating characteristic and related Malignancy.. Korean Journal of Radiology addresses concerns in the field of Magnetic resonance imaging by exploring it in line with topics in Hepatocellular carcinoma which intersect with Gadoxetic acid subjects. While work presented in it provided substantial information on Internal medicine, it also covered topics in Gastroenterology, Oncology and Cardiology.

Publication chance based on affiliation

The publication chance index shows the ratio of articles published by the best research institutions in the journal edition to all articles published within that journal. The best research institutions were selected based on the largest number of articles published during all editions of the journal.

The chart below presents the percentage ratio of articles from top institutions (based on their ranking of total papers).Top affiliations were grouped by their rank into the following tiers: top 1-10, top 11-20, top 21-50, and top 51+. Only articles with a recognized affiliation are considered.

During the most recent 2021 edition, 8.65% of publications had an unrecognized affiliation. Out of the publications with recognized affiliations, 65.26% were posted by at least one author from the top 10 institutions publishing in the journal. Another 2.63% included authors affiliated with research institutions from the top 11-20 affiliations. Institutions from the 21-50 range included 13.68% of all publications and 18.42% were from other institutions.

Returning Authors Index

A very common phenomenon observed among researchers publishing scientific articles is the intentional selection of journals they have already attended in the past. In particular, it is worth analyzing the case when the authors participate in the same journal from year to year.

The Returning Authors Index presented below illustrates the ratio of authors who participated in both a given as well as the previous edition of the journal in relation to all participants in a given year.

Returning Institution Index

The graph below shows the Returning Institution Index, illustrating the ratio of institutions that participated in both a given and the previous edition of the conference in relation to all affiliations present in a given year.

The experience to innovation index

Our experience to innovation index was created to show a cross-section of the experience level of authors publishing in a journal. The index includes the authors publishing at the last edition of a journal, grouped by total number of publications throughout their academic career (P) and the total number of citations of these publications ever received (C).

The group intervals were selected empirically to best show the diversity of the authors' experiences, their labels were selected as a convenience, not as judgment. The authors were divided into the following groups:

• Novice - P < 5 or C < 25 (the number of publications less than 5 or the number of citations less than 25),
• Competent - P < 10 or C < 100 (the number of publications less than 10 or the number of citations less than 100),
• Experienced - P < 25 or C < 625 (the number of publications less than 25 or the number of citations less than 625),
• Master - P < 50 or C < 2500 (the number of publications less than 50 or the number of citations less than 2500),
• Star - P ≥ 50 and C ≥ 2500 (both the number of publications greater than 50 and the number of citations greater than 2500).

The chart below illustrates experience levels of first authors in cases of publications with multiple authors.

Comparative Analysis of Similar Studies

While this article comprehensively outlines the Korean Journal of Radiology's research efforts on Radiology, Magnetic resonance imaging, Nuclear medicine, Surgery, and Internal medicine. A comparative piece detailing how this investigative work measures up against similar research initiatives from related journals would add a valuable perspective. For instance, looking at parallels or divergences in research focuses, methodologies, or findings could foster more thorough critical insight. Moreover, understanding the ranking of topics in comparison to other similar publications could give us a better understanding of where the Korean Journal of Radiology stands in the larger medical research community. For instance, a comparison with studies and programs that offer specialization in these key areas, such as the best online nursing schools in Georgia could provide valuable context to complement the in-depth focus provided. This comparative analysis would provide multi-dimensional viewpoints, spotlight key trends, identify unique findings, and ultimately create a more robust understanding of radiological research's evolving landscape. This information would also be integral for researchers seeking to identify potential gaps in the literature and future directions for their work.
