摘　　要：目的根据文献分布、增长规律,探讨近十年国内外CT低剂量领域的研究趋势和研究热点。资料与方法以Web of Science数据库中收录的2003～2012年国内外出版的CT低剂量研究论文为研究对象,采用Thomson Data Analyzer(TDA)Version2.1分析软件进行数据筛选,从作者合作趋势、机构合作趋势、国家分布、期刊发文趋势、高被引文献、学科分布、热点主题等方面进行文献计量学分析。结果 2003～2012年WebofScience共收录CT低剂量文献6725篇,单篇论文平均作者数6.05,合作率为95.7%;单篇论文平均机构数2.56,合作率为73.9%,均呈现逐年递增趋势。中国共发表论文318篇,2012年文献发表量居世界第3位。Medical Physics、European Journal of Radiology和American Journal of Roentgenology发表的CT低剂量文献快速增长。CT低剂量的研究热点涉及肺癌筛查、冠状动脉造影、肺动脉栓塞检查、CT辐射剂量等。结论 CT低剂量研究涉及多作者、多机构、多学科的交叉合作,中国CT低剂量研究的趋势和热点基本保持与世界同步,但是论文质量及数量尚有待进一步提高。To investigate the research trends and fbcus in low-dose CT study at home and abroad in recent ten years according to literature distribution and growth law. Materials and Methods The papers on low-dose CT research published at home and abroad from 2003 to 2012 which were abstracted in Web of Science database were taken as study objects. Data filtering was performed by using the Thomson Data Analyzer （TDA） Version 2.1 analysis software for the trend of cooperation, institutional cooperation trends, national distribution of the papers trend, high-citations, subject distribution, hot topics and other aspects to do bibliometric analysis. Results A total number of 6725 papers on low-dose CT from 2003-2012 were abstracted by Web of Science. The average number of authors in single papers was 6.05 （cooperation rate, 95.7%）, and the average number of institutions in single papers was 2.56 （cooperation rate, 73.9%）, which both showed an increasing trend year by year. 318 Chinese papers were published, and the published literatures in 2012 were ranked third in the world. Papers on low-dose CT, which were published in Medical Physics, European Journal of Radiology and the American Journal of Roentgenology, had rapid growth. The research focus of low-dose CT study involved in lung cancer screening, coronary angiography, pulmonary embolism examination, CT radiation dose and so on. Conclusion CT low-dose studies involve in collaboration between multi-author, multi-institutional and multi-disciplinary. The trends and locus of low-dose CT study in China keep pace with the world, and the quality and quantity of paper need to be further improved
