摘　　要：高级别胶质瘤(high-grade glioma,HGG)与脑转移瘤(brain metastasis,BM)为颅内最常见的两类恶性肿瘤,二者的治疗方式及预后存在差异。因此,术前准确诊断两者具有重要意义。本文对常规MRI上的特异性影像学征象及多种功能性MRI鉴别HGG与BM的研究进展进行综述,以期为临床上对二者的鉴别诊断及后续研究提供参考。High-grade glioma(HGG)and brain metastasis(BM)are the two most common types of malignant intracranial tumors.Their treatment strategy and prognosis are different.Therefore,it is of great significance to differentiate HGG from BM preoperatively.This paper reviews the research progress of specific imaging signs on conventional MRI and the research progress of multiple functional MRI(fMRI)in the differential diagnosis of HGG and BM,in order to provide reference for clinical differential diagnosis and follow-up research.
