The utilization of functional magnetic resonance imaging (fMRI) in studying the mechanisms and treatment of chronic pain has gained significant popularity. However, there is currently a dearth of literature conducting bibliometric analysis on fMRI studies focused on chronic pain.
All the literature included in this study was obtained from the Science Citation Index Expanded of Web of Science Core Collection. We used CiteSpace and VOSviewer to analyze publications, authors, countries or regions, institutions, journals, references and keywords. Additionally, we evaluated the timeline and burst analysis of keywords, as well as the timeline and burst analysis of references. The search was conducted from 2004 to 2023 and completed within a single day on October 4th, 2023.
A total of 1,327 articles were retrieved. The annual publication shows an overall increasing trend. The United States has the highest number of publications and the main contributing institution is Harvard University. The journal PAIN produces the most articles. In recent years, resting-state fMRI, the prefrontal cortex, nucleus accumbens, thalamus, and migraines have been researched hotspots of fMRI studies on chronic pain.
This study provides an in-depth perspective on fMRI for chronic pain research, revealing key points, research hotspots and research trends, which offers valuable ideas for future research activities. It concludes with a summary of advances in clinical practice in this area, pointing out the need for critical evaluation of these findings in the light of guidelines and expert recommendations. It is anticipated that further high-quality research outputs will be generated in the future, which will facilitate the utilization of fMRI in clinical decision-making for chronic pain.
功能磁共振成像（fMRI）在研究慢性疼痛的机制和治疗方面的应用已经得到了广泛的关注。然而，目前针对慢性疼痛的 fMRI 研究进行文献计量分析的文献还很少。
本研究中的所有文献均来自 Web of Science 核心合集的科学引文索引扩展版。我们使用 CiteSpace 和 VOSviewer 来分析出版物、作者、国家或地区、机构、期刊、参考文献和关键词。此外，我们还评估了关键词的时间线和突发分析，以及参考文献的时间线和突发分析。检索时间从 2004 年到 2023 年，于 2023 年 10 月 4 日一天内完成。
共检索到 1327 篇文章。年度出版物呈总体上升趋势。美国发表的文献数量最多，主要贡献机构是哈佛大学。发表文章最多的期刊是 PAIN。近年来，静息态 fMRI、前额叶皮层、伏隔核、丘脑和偏头痛已成为慢性疼痛 fMRI 研究的热点。
本研究深入探讨了 fMRI 用于慢性疼痛研究，揭示了该领域的研究重点、热点和趋势，为未来的研究活动提供了有价值的思路。最后总结了该领域临床实践的进展，并指出需要根据指南和专家建议对这些发现进行批判性评估。预计未来将有更多高质量的研究成果问世，这将有助于 fMRI 在慢性疼痛的临床决策中的应用。
