CT或MRI应用于胰腺假性囊肿的文献计量学分析

Bibliometric Analysis of CT or MRI Application in Pancreatic Pseudocyst

目的通过对近10年来CT或MRI应用于胰腺假性囊肿的研究现状的相关论文进行文献计量学分析,为影像学相关专业人员深入研究该领域提供参考信息。方法通过主题词检索Pub Med数据库中从2003年1月1日至2014年9月20日期间发表的CT或MRI应用于胰腺假性囊肿方面的相关文献,采用Bicomb书目分析软件统计相关文献的年代分布、来源期刊、第一作者及主要主题词和副主题词,并截取频次大于5次的主要主题词+副主题词为高频主题词,建立主题词词篇矩阵,利用SPSS 20.0统计软件对矩阵做聚类分析,获得该领域高频主题词的共词聚类分析树图,从而反映该领域研究的现状及热点。结果筛选出CT或MRI应用于胰腺假性囊肿的文献342篇。10年来CT或MRI应用于胰腺假性囊肿的研究热度逐年缓慢上升,至2008后热度逐渐减退。相关文献共发表在164种期刊上,根据布拉德福定律有16种期刊被划分为核心区,共发表文章115篇,占总文献量的33.0460%。有10人发表相关文献至少2篇,其中美国的Bhasin DK发表7篇文章,为该领域最活跃的研究者。出现频次超过5次的主要主题词+副主题词33个,通过对这33个高频主题词+副主题词聚类分析得到5个研究热点。结论目前对CT或MRI应用于胰腺假性囊肿影像学的研究热点主要集中在对胰腺假性囊肿内镜和手术治疗、病因学、并发症、诊断、病理学研究这5个方面。

Objective To explore the current status and tendency of the application of CT or MRI in the pancreatic pseudocyst using bibiometrie analysis for relative documents, and provide reference information for the future research of radiology. Methods Bibliographies from research literatures of CT or MRI application in the pancreatic pseudocyst from January 1, 2003 to September 20, 2014 in PubMed database were downloaded. The publication years, journals, the first authors, and the frequency of subject headings and subheadings were extracted from them by Bicomb 2.0 software. The subject headings and subheadings appeared more than five times were intercepted as high frequency ones, then created the high frequency subject headings and subheadings co-occurrence matrix. SPSS 22.0 statistical software was applied for clustering analysis with this matrix, then got the major hotspots. Results A total of 342 literatures were screened out. The research of CT or MRI application in the pancreatic pseudocyst increased slowly year by year in recent 10 years, then slowly decreased after 2008 year. The related literatures were published in the 164 journals, in which 16 journals （115 literatures were published） were core area distribution according to the Bradford law. There were 10 authors at least 2 published literatures, in who Bhasin DK in USA published 7 literatures, was the most active researcher in this field. The number of high frequency subject headings and subheadings was 33 and among which 5 research hotspots were clustered. Conclusion Research hotspots about CT or MRI application in pancreatic pseudocyst mainly focuses on five aspects below： pathology, diagnosis, therapy, complications, and etiology.
