肝脏三维影像技术的文献计量学研究

Bibliometric analysis of application of three-dimensional imaging in liver

目的运用文献计量学方法分析最近10年肝脏三维影像技术的相关文献,为肝脏外科医师提供该领域的研究现状及研究热点的相关信息。方法下载PubMed数据库中近10年发表的肝脏三维影像技术的相关文献条目,利用Bicomb 2.0书目分析软件统计文献发表的年代、发表期刊、第一作者及主要主题词+副主题词,并截取频次大于10的主要主题词+副主题词为高频主题词+副主题词,建立词篇矩阵,利用SPSS 22.0统计软件对词篇矩阵做聚类分析,并获得高频主题词+副主题词树状图。结果共筛选出2007年11月至2017年11月期间发表的关于肝脏三维影像技术的文献269篇,发现近10年来对该领域的研究热度于2016年达到高峰,发表相关文献的核心期刊有12种,发表至少3篇相关文献的第一作者有6人。通过对高频主题词+副主题词聚类分析得到该领域的研究热点在于精准肝脏外科。结论目前关于三维影像技术在肝脏外科中应用的研究热点在于精准肝脏外科。

Objective To analyze relevant literatures of three-dimensional （3D） imaging in liver using bibiometric analysis, and to provide a current status and hotspot in this filed in future for liver surgeon. Methods The bibliographies of liver 3D imaging from November 2007 to November 2017 in the PubMed database were downloaded. The publication years, journals, the first authors, and the frequency of subject headings＋subheadings were extracted by Bicomb 2.0 software. The subject headings＋subheadings appeared more than 10 times were intercepted as high frequency ones, then created the high frequency subject headings＋subheadings co-occurrence matrix. SPSS 22.0 software was applied for clustering analysis with this matrix to get the topic hotspot. Results A total of 269 literatures were screened out. The research in this field reached its peak in 2016. The core area of journals contained 12 journals. There were 6 authors published at least 3 relevant literatures. The number of high frequency subject headings＋subheadings was 16. The research hotspot of liver 3D imaging was precise liver surgery. Conclusion Research hotspot of application of 3D imaging in liver is precise liver surgery in recent 10 years.
