(1) Objective-Intraoperative Magnetic Resonance Imaging (IOMRI) guided surgery has revolutionized neurosurgery and has especially impacted the field of Neuro-Oncology, with randomized controlled trails demonstrating improved resection, fewer postoperative deficits and enhanced survival rates. Bibliometric analysis allows for analysing chronological trends and measuring the impact and directions of research in a particular field. To the authors' knowledge, this is the first Bibliometric analysis conducted on IOMRI. (2) Methods-a title specific search of the database was executed using the keywords 'intraoperative MRI', 'intraoperative magnetic resonance imaging', and "IOMRI' on 23rd April 2021. Results-663 articles met the inclusion criteria and were included in the final analysis. In addition, the 100 most cited were analysed as well. Among these 100 articles, 76 were original research papers, while 14 others were review articles. Amongst all the authors, Ganslandt contributed the maximum number of articles, with USA being the largest single source of these articles, followed by Germany. Interestingly, a shift of trends from "Image guided surgery' and 'accuracy' in the early 2000s to 'extent of resection', 'impact', and 'survival' in the later years was noted. (3) Conclusions-IOMRI has now become an integral part of neurosurgery, especially in neuro-oncology. Focus has now shifted from implementation to refinement of technique in the form of functional and oncological outcomes. Therefore, future research in this direction is imperative and will be of more impact that in any other sub-field related to IOMRI.
(1) 目的——术中磁共振成像（IOMRI）引导下的手术彻底改变了神经外科领域，尤其对神经肿瘤学领域产生了重大影响，随机对照试验表明其提高了切除率，减少了术后缺陷并提高了生存率。文献计量分析有助于分析时间趋势并衡量特定领域研究的影响和方向。据作者所知，这是首次对IOMRI进行的文献计量分析。(2) 方法——于2021年4月23日使用关键词“术中MRI”“术中磁共振成像”和“IOMRI”对数据库进行特定标题搜索。结果——663篇文章符合纳入标准并被纳入最终分析。此外，还对被引用次数最多的100篇文章进行了分析。在这100篇文章中，76篇是原创研究论文，另外14篇是综述文章。在所有作者中，甘斯兰特贡献的文章数量最多，其中美国是这些文章的最大单一来源国，其次是德国。有趣的是，注意到从21世纪初的“图像引导手术”和“准确性”趋势转变为后期的“切除范围”“影响”和“生存率”趋势。(3) 结论——IOMRI现已成为神经外科尤其是神经肿瘤学不可或缺的一部分。现在重点已从技术的实施转向以功能和肿瘤学结果形式的技术完善。因此，这一方向的未来研究势在必行，且将比与IOMRI相关的任何其他子领域的研究产生更大影响。
