磁敏感加权成像在脑胶质瘤中的应用进展

Advances in the application of susceptibility weighted imaging in brain gliomas

脑胶质瘤是中枢神经系统最常见的恶性肿瘤,其鉴别诊断、术前病理分级、基因分型、术前规划、术后疗效评估对实施个体化治疗具有重要意义。磁敏感加权成像(susceptibility weighted imaging,SWI)是利用不同组织间磁敏感差异成像的技术,能够清楚显示脑胶质瘤内引流静脉及出血产物。本综述介绍了SWI的基本技术原理,以及SWI在脑胶质瘤的诊断、治疗和影像组学方面的应用和研究进展,将为脑胶质瘤的诊断、治疗以及预后评估等提供更多的参考依据。

Gliomas are the most common malignant tumors of the central nervous system.Their differential diagnosis,preoperative pathological grading,genetic typing,preoperative planning,and postoperative efficacy evaluation are of great significance for the implementation of personalized treatment.Susceptibility weighted imaging(SWI)is a technology that uses the differences in magnetic susceptibility between different tissues to create images,which can clearly show draining veins and hemorrhagic products within gliomas.This review introduces the basic technical principles of SWI,as well as its applications and research progress in the diagnosis,treatment,and radiomics of gliomas,providing more reference points for the diagnosis,treatment,and prognosis assessment of gliomas.
