다국어 초록 (Multilingual Abstract)

Objective: To evaluate scientific papers published by radiologists in high impact general medical journals between 1996 and 2010.
Methods: A MEDLINE search was performed in five high impact general medical journals(AIM, BMJ, JAMA, Lancet, and NEJM) for all articles of which a radiologist was the first author between 1996 and 2010. The following information was abstracted from the original articles : radiological subspecialty, imaging technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, collaboration, and country of the first author.
Results: Of 216 (0.19%) articles were published by radiologists in five general medical journals between 1996 and 2010, 83 were original articles. Fifteen (18.1%) original articles were concerned with the field of vascular/interventional radiology, 24 (28.9%) used combined imaging techniques, 76 (91.6%) were clinical research, 63 (75.9%) had sample size of >50, 65 (78.3%) were prospective, 78 (94.0%) performed statistical analysis, 83 (100%) showed positive study outcomes, 57 (68.7%) were funded, 49 (59.0%) had from four to seven authors, and 79 (95.2%) were collaborative studies.
Conclusions: A very small number (0.19%) in five high impact general medical journals was published by radiologists between 1996 and 2010.
