摘要
目的:应用CiteSpace可视化分析DTI技术在轻度认知障碍(MCI)方面的研究现状及热点.方法:以web of science核心合集数据库为数据来源,利用CiteSpace V软件绘制关键词共现图、聚类图、突现图及文献共被引图,对2018年1月—2023年12月数据库中MCI及DTI相关的研究进行关键词节点分析,总结该区域的研究热点和趋势.结果:共检索出DTI应用于MCI领域的文献462篇:①关键词共现图中,主要以阿尔茨海默病、DTI、MRI等研究为主;②关键词聚类包括扩散张量成像、海马、认知损害、创伤性脑损伤、阿尔茨海默病、精神分裂症、肌萎缩侧索硬化症、认知障碍和磁共振扩散峰度成像共9个聚类;③关键词突现图中,创伤性脑损伤、神经退行性变、通路、默认模式网络这个关键词在2018年出现并持续到2023年12月,是目前国外研究的热点及前沿;④使用文献共被引分析功能,对数据文献的参考文献进行引用数量排名,本研究中心性＞0.15的有5篇参考文献,旨在发掘该研究领域的核心文献.结论:本文献计量学研究的结果提供了 DTI在MCI研究领域的现状和趋势,并可能帮助研究人员确定该领域的热点话题和探索新的研究方向.
Abstract
Objective:To visually analyze the research status and hotspots of DTI applied to MCI with CiteSpace.Methods:Using the core collection database of web of science as the data source,CiteSpace V software was used to draw keyword co-occurrence map,cluster map,emergence map and literature co-citation map,and keyword node analysis was carried out on MCI and DTI related studies in the database from January 2018 to December 2023.The research hotspots and trends in this region were summarized.Results:A total of 462 literatures on the application of DTI to MCI were retrieved:①In the keyword co-occurrence map,the main research was"Alzheimer's disease,DTI,MRI";(2)The keywords cluster included 9 clusters of"diffusion tensor imaging,hippocampus,cognitive impair-ment,traumatic brain injury,Alzheimer's disease,schizophrenia,amyotrophic lateral sclerosis,cogni-tive impairment,magnetic resonance diffusion kurtosis imaging";③The key words of traumatic brain injury,neurodegeneration,pathway,and default mode network,emerged from 2018 and lasted until the end of 2023,which was currently the hot spot and frontier of foreign research;④The function of co-ci-tation analysis was used to rank the number of references in the data literature.In this study,there were 5 references with centrality＞0.15,aiming to discover the core literature in this research field.Conclusion:The findings of this bibliometrics study provide the current status and trends of DTI in the field of MCI research and may help researchers identify hot topics in the field and explore new research direction.
