We performed a comparative bibliometric study of the scientific publications by radiologists in radiology and nonradiology journals in 2000 and 2010.
A PubMed database search was conducted for all articles published by radiologists in journals indexed by Science Citation Index and Science Citation Index Expanded in 2000 and 2010 by using the search term "radiol*" or "imag*" in the first author's affiliation field. Subject categories and the impact factor (IF) of the publishing journal, which were based on information contained in the Institute for Scientific Information's Web of Knowledge Journal Citation Reports, were assigned to each article. We compared the number and proportion of articles published and the IF of radiology and nonradiology journals.
Of the articles published by radiologists, 25.4% (1677/6598) in 2000 and 35.7% (4479/12,559) in 2010 were published in nonradiology journals. The articles were published in 552 and 1329 nonradiology journals in 2000 and 2010, respectively. The IFs of the nonradiology journals were significantly higher than those of the radiology journals (2.4 ± 3.0 vs 1.5 ± 1.2 in 2000 and 3.2 ± 3.8 vs 2.3 ± 1.4 in 2010; p < 0.0001). When we considered the subject categories, "Oncology," "Surgery," and "Neurosciences" accounted for the highest proportion of radiologic publications.
Radiologic publications in nonradiology journals have increased in terms of number, percentage, journal IF, and range of contributions.
我们对 2000 年和 2010 年放射科医生在放射学和非放射学期刊上发表的科学出版物进行了比较文献计量学研究。
使用搜索词“radiol*”或“imag*”在第一作者所属机构字段中，对科学引文索引和科学引文索引扩展中索引的期刊发表的所有放射科医生文章进行 PubMed 数据库搜索。根据信息科学研究所 Web of Knowledge 期刊引文报告中包含的内容，为每篇文章分配主题类别和出版期刊的影响因子（IF）。我们比较了放射学和非放射学期刊发表的文章数量和比例以及 IF。
放射科医生发表的文章中，2000 年有 25.4%（1677/6598）和 2010 年有 35.7%（4479/12559）发表在非放射学期刊上。2000 年和 2010 年分别有 552 种和 1329 种非放射学期刊发表了这些文章。非放射学期刊的 IF 明显高于放射学期刊（2000 年为 2.4 ± 3.0 与 1.5 ± 1.2，2010 年为 3.2 ± 3.8 与 2.3 ± 1.4；p < 0.0001）。当我们考虑主题类别时，“肿瘤学”、“外科学”和“神经科学”占放射学出版物的比例最高。
放射学出版物在非放射学期刊上的数量、比例、期刊 IF 和投稿范围均有所增加。
