To assess the knowledge framework around magnetic resonance elastography (MRE) and to explore MRE research hotspots and emerging trends.
The Science Citation Index Expanded of the Web of Science Core Collection was searched on 22 October 2021 for MRE-related studies published between 1995 and 2021. Excel 2016 and CiteSpace V (version 5.8.R3) were used to analyze the downloaded data.
In all, 1,236 articles published by 726 authors from 540 institutions in 40 countries were included in this study. The top 10 authors published 57.6% of all included articles. The 3 most productive countries were the USA (n=631), Germany (n=202), and France (n=134), and the 3 most productive institutions were the Mayo Clinic (n=240), Charité (n=131), and the University of Illinois (n=56). The USA and the Mayo Clinic had the highest betweenness centrality among countries and institutions, respectively, and played an important role in the field of MRE. In this study, the 24,347 distinct references were clustered into 48 categories via reasonable clustering using specific keywords, forming the knowledge framework. Among the 294 co-occurring keywords, "hepatic fibrosis", "stiffness", "skeletal muscle", "acoustic strain wave", "in vivo", and "non-invasive assessment" were research hotspots. "Diagnostic performance", "diagnostic accuracy", "hepatic steatosis", "chronic hepatitis B", "radiation force impulse", "children", and "echo" were frontier topics.
Scientometric and visualized analysis of MRE can provide information regarding the knowledge framework, research hotspots, frontier areas, and emerging trends in this field.
评估磁共振弹性成像（MRE）的知识框架，探索MRE的研究热点和新趋势。
于2021年10月22日在科学网核心合集的科学引文索引扩展版中检索1995年至2021年发表的与MRE相关的研究。使用Excel 2016和CiteSpace V（5.8.R3版）分析下载的数据。
本研究共纳入了来自40个国家540个机构的726位作者发表的1236篇文章。前10位作者发表了所有纳入文章的57.6%。发文量最多的3个国家是美国（n = 631）、德国（n = 202）和法国（n = 134），发文量最多的3个机构是梅奥诊所（n = 240）、夏里特医学院（n = 131）和伊利诺伊大学（n = 56）。美国和梅奥诊所在国家和机构中分别具有最高的中介中心性，在MRE领域发挥了重要作用。在本研究中，通过使用特定关键词进行合理聚类，将24347条不同的参考文献聚类为48类，形成了知识框架。在294个共现关键词中，“肝纤维化”“硬度”“骨骼肌”“声应变波”“体内”和“无创评估”是研究热点。“诊断性能”“诊断准确性”“肝脂肪变性”“慢性乙型肝炎”“辐射力脉冲”“儿童”和“回声”是前沿主题。
对MRE进行科学计量和可视化分析可以提供有关该领域知识框架、研究热点、前沿领域和新趋势的信息。
