摘　　要：胶质瘤术后复发与放射性脑损伤在常规MRI上均可表现为新增强化灶或原强化灶增大,常容易造成误诊,而二者的临床治疗方案却截然不同。因此,早期准确的诊断对临床制订治疗方案具有重要的指导意义。探讨功能MRI早期鉴别胶质瘤术后复发与放射性脑损伤,一直是神经肿瘤影像学研究的难点也是热点问题。作者对当前MRI鉴别胶质瘤术后复发与放射性脑损伤的影像学研究进展予以综述。It remains challenging to distinguish radiation-induced brain injury from tumor recurrence in treated patients with high grade glioma（HGG） due to overlapping radiologic features. Both may present with new and/or increasing enhancing mass lesions and fulfill standard criteria for progression. Distinguishing radiation-induced brain injury from tumor recurrence is crucial for treatment planning. The purpose of this review is to outline the current MRI researches on differential diagnosis between tumor recurrence and radiation-induced brain injury.
