MRI评价半月板损伤：基于SCI数据库10年的文献分析*

背景：磁共振成像为非侵入性直接成像评价半月板的主要影像学检查方法，目前已成为学科界的共识。 目的：利用SCI数据库文献检索和深度分析功能，对于MRI评价半月板的10年文献资料趋势进行多因素探讨。 设计：文献计量学分析。 资料提取：以英文“meniscus(半月板)，damage或injury(损伤)，MRI(磁共振成像)”为关键词，检索SCI数据库2001-01/2010-12的相关文献。分析检索结果，并将分析结果及资料导出，以文字和图表的形式描述。 纳入标准：收集与磁共振诊断半月板损伤类型、治疗、效果和影像学表现相关的文献。文献类型包括研究原著、综述、技术研究及会议录。排除未发表的文章及会议摘要，以及需要手工检索分析和电话追踪的文献。 主要数据的判定指标：以文献的国家分布、机构信息、基金资助情况、文献发表年份、学科分布情况、被引频次、发表较多文献作者和文献学科分类进行相关分析。 结果：检索文献总量448篇，其中美国发表数最多，占文献量的43%，基金资助项目较分散，文献发表数量以及被引频次总体呈逐年升高的趋势。 结论：通过文献计量学方法对来源于SCI数据库关于MRI评价半月板损伤的文献进行分析，可为了解该领域的概貌、现状和研究者进一步确定热点难点提供有价值的参考。

Evaluation of meniscus injury by magnetic resonance imaging: A documentary analysis based on Science Citation Index from 2001 to 2010

BACKGROUND: It is well known that magnetic resonance imaging (MRI) is the main imaging test method for the evaluation of meniscus injury as a non-invasive technology. OBJECTIVE: To multivariately analyze the literature on meniscus injury diagnosed by MRI through Science Citation Index Database (SCI) and its analysis tool. DESIGN: Bibliometric analysis. DATA RETRIEVAL: A computer-based online search of related literatures was performed in SCI database from January 2001 to December 2010 using the key words of “meniscus, damage or injury, MRI”. The retrieval results were analyzed, and the trends were described in words and graphics. SELECTION CRITERIA: ①The documents related to the types, treatment, effects and imaging features of meniscus injury diagnosed by MRI were selected; ②the literatures included articles, reviews, technical studies and proceedings papers; ③Unpublished articles, meeting abstracts and those needed to be obtained by manual or phone search were excluded. MAIN OUTCOME MEASUREMENTS: The literatures were analyzed by national distribution, institutional information, foundation, publish year, discipline distribution, citation frequency and authors. RESULTS: A total of 448 literatures were retrieved. The United States published the largest number of the articles, with 43% of all literature in the field. The funded projects were dispersed. The amount and citation frequency of the literature were increased year by year. CONCLUSION: This paper provides a valuable reference for researchers to understand the overview and present situation of this field in order to set further research.
