The papers in the Journal of the Korean Radiologic Society(JKRS) during recent three years were surveyed by analysis of their types, topics, organs, employed modalities, and cited literatures. Citation analysis is a methodof studying interrelationships between papers and journals, and the most important application of citationanalysis is in studies of science policy and research evaluation to evaluate the implementation of science policyand to monitor research performance. Using these citation analysis to map the journal communications network mayindicate to more efficient scientific progress. Total number of papers published by JKRS for recent 3 years was 473 papers(Clinical: 354, Case report: 91, Experimental: 26, Educational: 2). The most common organ system of thepapers was abdomen(head and neck, chest, musculoskeletal, cardiovascular, and urologic system in the order ofdecreasing frequency). The most popular topppic was techniques including newer modalities and interventionalradiology, and normal measurement, tuberculosis, hepatoma, normal anatomy and the like follwed. Total number ofcited references was 8,642(18.26 per one paper), and the average number of authors per paper was 4.83. The most frequently used modality was CT(41%) followed by simple radiography, ultrasonogram, fluoroscopic study, angiography, nuclear imaging, and MRI. Using this kind of analysis as a guide for writing a paper for the JKRS, itcould be well-organized and uplifted in its format and contents.
