2013—2023 年血管周围间隙相关研究的 文献计量学分析.

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. [ABSTRACT FROM AUTHOR]
