摘要
目的:通过文献计量学方法分析2001年至2010年发表在中国主要的影像学期刊《中华放射学杂志》的论著性文章,从而发现影像学科学研究的特征及发展方向。资料和方法:分析评价发表在《中华放射学杂志》的2378篇论著性文章,评价每篇文章的摘要及全文的下述指标:影像学的亚专科,影像技术的类型,研究的类型、方法、统计学方法,及研究有无基金资助,文章的作者数目,第一作者的所从事的专业、单位的级别、所在的省会,同时动态分析上述这些指标在过去10年的变化趋势。结果:科学研究最多的亚专科是中枢神经系统(403/2378,16.9%),第二和第三的分别是血管介入(369/2378,15.5%),腹部(331/2378,13.9%)。834篇(35.1%)论著性的科学研究文章中使用了MRI的方法或者678篇(28.5%)使用了CT的方法。2034篇(85.5%)的科学研究是临床实验研究,1838篇(77.3%)为回顾性研究。10年内的时间趋势中,显著性上升的为乳腺亚专科,MRI成像技术,基础性研究的数量,大于50的样本量,使用统计学方法的文章,基金支持的文章数目,大于7位作者的数目和江苏、福建和新疆地方发表文章的数目;显著性下降的为超声成像技术和介入治疗技术,无统计学方法的文章数目,小于4名作者数目和山西省发表的文章数目。结论:应用文献计量学分析方法分析发表在中华放射学杂志上2001至2010年的论著性文章的科学研究的特征及发展变化方向可以为医学影像学的科学研究人员提供了更多有用的信息。
Purpose:To determine the characteristics and trends of the original articles published in Chinese Journal of Radiology, between 2001 and 2010. Materials and Methods:Al 2378 original articles published in Chinese Journal of Radiology between 2001 and 2010 were evaluated. The fol owing information was abstracted from each article: radiologic subspecialty, radiologic technique used, type of research, sample size, study design, statistical analysis, study outcome, declared funding, number of authors, afifliation of the ifrst author, and province of the ifrst author. In addition, al the variables examined were presented along with the trend over time. Results:The most common subspecialty of study was neuroradiology 403 of 2378,16.9%), fol owed by vascular/interventional (369 of 2378, 15.5%). And Abdominal (331of 2378,13.9%) .A total of 834 (35.1%) original articles used magnetic resonance (MR) imaging or 678 (28.5%) computed tomography (CT), 2034 (85.5%) were clinical research articles, 819 (34.4%) had sample size of between 20 and 50 , 1838 (77.3%) were retrospective, 1309 (55%) performed statistical analysis, 2337 (98.3%) showed positive study outcome, 1744 (77.3%) were not funded, 1529 (64.3%) had four to seven authors, and 2283 (96%) were writ en by the primary author who was from a department of radiology or radiology-related specialties. The province published Beijing (663, 27.9%), Guangzhou(349, 14.7%), Shanghai(281, 11.8%). In the time trend analysis, the fol owing variables showed a signiifcantly positive trend: Brest subspecialty, MR imaging as the radiologic techniques, type of research as other (nonbasic, nonclinical), sample size of more than 50, more than seven as the number of authors, Jiangsu,fujian ad xinjiang as province of the first author. On the other hand,vascular/interventional subspecialty, showed a significantly negative trend. Conclusion:The bibliometric analysis of the Chinese Journal of Radiology journal w
