Abstract

Abstract: Objective To analyze the current research status, hotspots, and frontier fields of perivascular spaces from 2013 to 2023 based on bibliometric analysis.
Methods The related English article of perivascular spaces was retrieved in the Web of Science Core Collection from January 1, 2013 to June 19, 2023. CiteSpace V6.3.R1 software was used to analyze the cooperation network among the publishing countries, institutions and authors; the co-citation network of reference, first author of reference and journals; the co-occurrence network of keywords, burst analysis of keywords and reference co-citation. VOSviewer 1.6.15 software was used for keywords cluster analysis.
Results A total of 1549 papers were included. The annual publications from 2013 to 2023 showed an overall increasing trend. The United States ranked the first and China ranked the second. The top three prolific institutions were Harvard University, Massachusetts General Hospital and University of Edinburgh. Cooperative network analysis showed that the cooperation between countries was close and domestic institutions collaborated less with other institutions. Wardlaw Joanna M from University of Edinburgh ranked the first in publications. The top ten keywords in co-occurrence network were small vessel disease, enlarged perivascular spaces, MRI, brain, Virchow-Robin spaces, Alzheimer’s disease, dementia, risk, stroke and glymphatic system. Cluster analysis of keywords showed that cerebral small vessel disease, dementia and MRI were current hotspots, and glymphatic system was a new research direction. Burst analysis of keywords suggested diffusion imaging has got much attention since 2021.
Conclusions The research on perivascular spaces has increased during the recent 10 years. Cerebral small vessel disease was the main hotspot and glymphatic system was a new direction. Diffusion tensor imaging was a frontier field.

Key words: Perivascular space; Bibliometrics; Cerebral small vessel disease; Glymphatic system; Diffusion imaging

摘要： 目的通过文献计量学的方法分析2013—2023年血管周围间隙的研究现状、热点及前沿领域。
方法在Web of Science核心合集数据库中检索2013年1月1日—2023年6月19日血管周围间隙相关英文论著。使用CiteSpace V6.3.R1软件分析文献的发文国家、研究机构、作者的合作网络，参考文献、第一作者、期刊的共被引网络，关键词的共现网络，关键词及参考文献共被引的突现情况；使用VOSviewer 1.6.15软件对关键词进行聚类分析。
结果共纳入1549篇文献。2013—2023年的年发文量整体呈增长趋势。美国的发文量最多，其次为中国。发文量位列前3的研究机构分别是哈佛大学、麻省总医院和爱丁堡大学。合作网络分析发现国家间合作相对紧密，国内研究机构与其他研究机构合作较少。爱丁堡大学的Wardlaw Joanna M发文量最多。关键词共现图谱显示前10个高频关键词分别为小血管病、扩大的血管周围间隙、MRI、脑、Virchow-Robin间隙、阿尔茨海默病、痴呆、风险、卒中和类淋巴系统。关键词聚类分析发现脑小血管病、痴呆、MRI 为当前研究热点，类淋巴系统为新兴的研究方向。关键词突现分析表明弥散成像从2021年至今备受关注。
结论近10年血管周围间隙的研究热度逐年攀升。脑小血管病是主要的研究热点，类淋巴系统为新兴的研究方向，前沿领域为弥散张量成像等MRI技术。

关键词: 血管周围间隙; 文献计量学; 脑小血管病; 类淋巴系统; 弥散成像
