To characterize the global research trend in radiology departments based on bibliometric indicators.
As a source of information, Science Citation Index Expanded and Journal Citation Reports from Web of Science Core Collection (WoSCC) were used. Annual trends, journals of publication, subject categories of journals, collaboration indexes between authors and institutions, network of cowords and most cited papers were identified and analysed. The period of study was 2009-2018.
283,587 downloaded papers were analysed. The number of articles was increasing, as well as the percentage of funded works. Papers were published in 7314 different journals, being the most productive Plos One (5077), followed by American Journal of Roentgenology (4602) and European Radiology (3644). Most productive subject categories of journals were Radiology, Nuclear Medicine & Medical Imaging (86,568 papers), Clinical Neurology (29,722) and Surgery (23,564). International collaboration has increased more than 5 points, from 15.2% in 2009 to 20.7% in 2018.
Most cited articles were published in high impact journals outside the scope of diagnostic imaging. Most influential topics included technical innovations within imaging modalities. MRI replaced conventional radiography and CT as the imaging technique of choice in imaging research.
基于文献计量指标，描述放射科的全球研究趋势。
我们将科学引文索引扩展版和来自 Web of Science 核心合集（WoSCC）的期刊引证报告用作信息来源。我们对年度趋势、出版物期刊、期刊主题类别、作者和机构之间的合作指数、共词网络以及被引频次最高的论文进行了识别和分析。研究时间为 2009 年至 2018 年。
我们分析了 283587 篇下载论文。文章数量在增加，资助工作的比例也在增加。论文发表在 7314 种不同的期刊上，其中发表论文最多的是 Plos One（5077 篇），其次是美国放射学杂志（4602 篇）和欧洲放射学杂志（3644 篇）。发表论文最多的期刊主题类别是放射学、核医学和医学影像学（86568 篇）、临床神经病学（29722 篇）和外科学（23564 篇）。国际合作增加了 5 个以上百分点，从 2009 年的 15.2%上升到 2018 年的 20.7%。
被引频次最高的文章发表在诊断影像学范围之外的高影响力期刊上。最有影响力的主题包括影像学模式内的技术创新。磁共振成像（MRI）取代了传统的 X 射线摄影术和计算机断层扫描（CT），成为影像学研究中首选的成像技术。
