目的探讨近十年国内 CT 低剂量领域的研究现状,揭示该领域的发展特点和一般规律,为该领域的进一步深入研究提供参考.方法以中国知网(CNKI)为搜索引擎,中国学术期刊网络出版总库(CAJD)为数据源,检索2002—2011年 CT 低剂量文献,采用 Thomson Data Analyzer(TDA)分析软件进行数据清洗.从年代、发文作者、地区、机构、基金等多方面进行文献计量学分析.结果2002—2011年 CAJD 数据库中共收录国内 CT 低剂量文献3148篇,累计作者7352人次,单篇论文平均作者数2.34,平均合著率为63.48%.发表3篇文献以上者为高产作者.发文作者来自471个机构,从属于8个机构类别,分布于我国33个地区,北京、上海两地发文量占45.9%.国内 CT 低剂量文献领域涉及10种核心期刊.2002—2011年,获基金资助文献共868篇,发文量逐年增长.结论国内 CT 低剂量研究与国际同期水平相比尚处于初级阶段,科研力量地区分布极不均衡.相关研究虽已涉及多机构、多系统、多学科,但发文数量、质量还有待进一步提高.加强 CT 低剂量相关的基础研究、完善 CT低剂量研究所涉及的医学伦理、临床科研方法等不足可加快该领域研究不断深入的步伐.

Objective The purposes of this study were to evaluate the characteristics and rule of the development in natioanl low -dose CT examination, and to supply a useful reference for future studies. Materials and Methods The journal articles in CNKI which were included by China Academic Journal Network Publishing Database (CAJD) from 2002 to 2011 were processed with Thomson Data Analyzer (TDA). Seven aspects were analyzed: time, authors, funds for scientific research,areal distribution,institutions, authors, and keywords. Results A total 3148 journal articles on low -dose CT examination and 7352 authors were found. The cooperative rate and degree were 63.48% and 2.34, respectively. The famous authors were those who published more than 3 articles. Authors were from 33 areas, 471 institutions of 8 systems. Beijing and Shanghai were the most productive areas, publishing 45.9% articles. There were 10 core journals in this research area. 868 articles were funded by certain grants, and number of articles was increased yearly, indicative of the importance of grant in promoting research. Conclusion The national low-dose CT research was in the young stage compared to the international research, and the research were not evenly distributed national wide. Though the researches have involved multi-institute, multi-system, multi -discipline, the quantities and qualities of papers still have improvement space. Strengthening basic research, improving medical ethics, and optimalizing clinical research methods would promote development of low-dose CT studies.
