Abstract Objective To make a visual analysis of the English literature on magnetic resonance research of acupuncture and show the research hotspots and trends in this field. Methods The literatures on acupuncture based on magnetic resonance published in the core database of Web of Science from January 2004 to April 2022 were obtained. The co-occurrence, clustering or emergence analysis of countries, authors, keywords, and co-cited references were performed using CiteSpace software, and the visual map was drawn. Results A total of 696 literatures were included, and the number of annual publications showed an overall upward trend. The number of publications from China was dominant, while the importance of publications from the United States was dominant. The top five authors were Jie Tian, Jian Kong, Wei Qin, Fanrong Liang, and Lijun Bai. The author with the highest centrality ranking was Jian Kong. The top five high-frequency keywords were functional magnetic resonance imaging, stimulation, pain, acupuncture, and electro-acupuncture. The keyword with the highest centrality ranking was functional magnetic resonance imaging. Keywords clustering results were cortex, randomized controlled trials, functional connectivity, anterior cingulate cortex, neural regeneration, human brain, rehabilitation, systematic review, brain activity, case reports. Meta analysis, default mode network, curative effect and so on were the key words that had emerged and lasted till now. The clustering results of co-cited references were pinprick specificity, depression, chronic low back pain, needle sensation, amygdala, migraine without aura, placebo, external closure, exercise, and subcortical stroke. Conclusion The research hotspots of magnetic resonance imaging of acupuncture include physiological response and acupoint specificity, therapeutic effect of acupuncture in diseases, systematic review and meta- analysis of previous literatures. Gratifying achievements have been made in this field in the past two decades, but there are still many gaps. In the future, more studies with rigorous design, wide range of diseases, and advanced analytical and modeling methods will emerge.
