摘要：脑胶质瘤是最常见的原发性脑肿瘤，在患者术后随访期间，如果出现新的强化病灶，影像学可能考虑为肿瘤复发或假性进展(PsP)。鉴别胶质瘤治疗后复发或假性进展对于患者后续治疗方式至关重要，而MRI在区分胶质瘤治疗后复发与假性进展具有明显优势。本文主要对脑胶质瘤术后复发与假性进展的MRI研究进展进行综述，总结了不同扫描技术、不同诊断方法对脑胶质瘤术后复发与假性进展的应用现状，立足于对两者充分认识及影像诊断技术的灵活应用，以期提高诊断准确率、降低误诊率。

    Abstract：Glioma is the most common primary brain tumor. During the postoperative follow-up period， if new enhanced lesions appear， imaging may be considered as tumor recurrence or pseudoprogression (PsP). Identifying recurrence or pseudoprogression after glioma treatment is crucial for the follow-up treatment of patients ......
