[Abstract] Objective Based on VOSviewer and CiteSpace, the current status, hotspots and trends of functional magnetic resonance imaging (fMRI) research on vascular cognitive impairment (VCI) were analyzed.Materials and Methods Relevant literatures on fMRI research on VCI included in the databases of CNKI, Wanfang and VIP until 2022 were retrieved. NoteExpress was used to deduplicate and screen the literature, VOSviewer drew the core author density view, and CiteSpace drew the institutional cooperation network graph, keyword clustering graph, keyword emergence graph and timeline graph.Results A total of 475 papers were included, involving 1168 authors, 148 journals and 212 institutions. The annual publication volume is increasing, and there are few co-author teams, and there is no connection between the teams; the published journals are mainly Chinese science and technology core journals, and a cooperative team with a certain institution as the core has not yet been formed, and the research institutions are independent and scattered. Keyword clusters include "cognitive function, pathogenesis, hippocampus, dementia, cerebral microbleeds, MRI, early diagnosis, hippocampal injury, hypertension" 9 clusters, "cerebral blood flow" in the keyword emergence is the emergent word that started in 2018 and continues to this day.Conclusions The popularity of fMRI research on VCI is gradually increasing. The hotspots focus on "cognitive function, pathogenesis, hippocampus, dementia, cerebral microbleeds, MRI, early diagnosis, hippocampal injury, hypertension", and "cerebral blood flow" is the research frontier in this field. In the field of fMRI research on vascular cognitive dysfunction, it is necessary to focus on institutional and team cooperation, grasp the research hotspots and frontiers, and improve the output of relevant scientific research results.
