To characterize the 100 most-cited articles in medical imaging.
The Scopus database was searched for citations to articles published in any of the 116 journals in the subject category "radiology, nuclear medicine, and medical imaging" at the Institute of Science Information Web of Science that the authors termed "imaging literature." Using the Scopus database, two authors searched electronic and print versions of these journals to determine the 100 most-cited articles. The following data were collected for each article: journal name, journal impact factor, number of authors, publication year, country in which the study was performed, department of all authors, article type, imaging modality, grant funding, and clinical subspecialty. Statistical and/or mathematic, magnetic resonance (MR) imaging technique, image processing and/or analysis and computer science, new imaging technique, and basic science articles were considered "preclinical." Using the Pearson correlation coefficient, the authors examined the relationship between journal impact factor and the number of top 100 cited articles included in the list.
Most studies were classified as preclinical (n = 75). Fifty-eight of the 100 articles were neuroradiology articles. NeuroImage had the most highly cited articles (n = 22). MR imaging was the most commonly studied imaging modality (n = 69). The authors of 51 articles were from radiology departments. Most articles were published from 1990 to the present (n = 87). There was a statistically significant positive correlation between journal impact factor and the number of top 100 cited articles (r = 0.46, P < .001).
Preclinical articles, primarily in the field of neurologic MR imaging, were highly represented in the top 100 cited articles in the medical imaging literature.
描述医学影像学中被引频次最高的 100 篇文章的特征。
在 Scopus 数据库中检索发表在科学信息研究所 Web of Science 收录的 116 种“放射学、核医学和医学影像学”期刊中任何一种期刊上的文章的引文，作者将这些文章称为“影像学文献”。两位作者使用 Scopus 数据库搜索这些期刊的电子和印刷版本，以确定被引频次最高的 100 篇文章。收集了每篇文章的以下数据：期刊名称、期刊影响因子、作者人数、发表年份、研究所在国家、所有作者的科室、文章类型、影像学模式、资助情况和临床亚专业。统计和/或数学、磁共振成像（MR）技术、图像处理和/或分析以及计算机科学、新的成像技术和基础科学文章被认为是“临床前”。作者使用 Pearson 相关系数，检查了期刊影响因子与列表中包含的前 100 篇高被引文章数量之间的关系。
大多数研究被归类为临床前（n = 75）。100 篇文章中有 58 篇为神经放射学文章。NeuroImage 发表的高被引文章最多（n = 22）。MR 成像最常被研究（n = 69）。51 篇文章的作者来自放射科。大多数文章发表于 1990 年至现在（n = 87）。期刊影响因子与前 100 篇高被引文章数量之间存在显著的正相关关系（r = 0.46，P <.001）。
临床前文章，主要是神经磁共振成像领域的文章，在医学影像学文献的前 100 篇高被引文章中占很大比例。
