多模态磁共振成像是将多种功能的磁共振成像技术融合的一种新兴颅脑成像技术，具有高精确度、高分辨率及低侵入性的优点，能够从解剖、功能及分子水平更加全面系统地获取脑组织信息。近年来随着磁共振成像技术的不断发展，多模态磁共振技术已广泛用于脑胶质瘤的临床诊疗中。了解多模态磁共振成像技术的原理及其在脑胶质瘤诊断分级、鉴别诊断及预后评估中的应用，有助于临床工作者更好地制定诊疗决策。“,”Multimodal magnetic resonance imaging is an emerging brain imaging technology that integrates multiple functions of magnetic resonance imaging technology. It has the advantages of high accuracy, high distinguishability and low invasiveness, and also can provide more comprehensive and systematic brain tissue information in the anatomical, functional and molecular levels. In recent years, with the continuous development of magnetic resonance imaging technology, multimodal magnetic resonance technology has been widely used in the clinical diagnosis and treatment of glioma. Therefore, understanding the principles of multimodal magnetic resonance imaging technology and its application in grading, differential diagnosis and prognostic assessment of glioma can help clinicians make better diagnosis and treatment decisions.
