目的 探讨MRI在脑胶质瘤诊断及 治疗随访中的应用价值。方法 回顾性分 析2008年3月-2011年10月我院收治的32例 经手术病理证实的脑胶质瘤患者的临床 资料，所有病例患者均进行MRI诊断，观 察患者MRI表现及肿瘤病理类型，患者术 后进行随访，分析患者治疗随访后其MRI 平扫和增强扫描影像学表现，以探讨MRI 在脑胶质瘤治疗随访中的应用价值。结果 32例病例患者中星形细胞瘤18例(包含毛 细胞型星形细胞瘤，弥漫型星形细胞瘤以 及胶质母细胞瘤等)；少突胶质瘤6例，室 管膜肿瘤5例，脉络丛乳头状瘤3例，各类 型脑胶质瘤其MRI影像学表现各异。治疗 后随访观察发现18例表现为反应性强化， 5例残余肿瘤，9例复发，MRI表现亦各不 相同。结论 MRI在脑胶质瘤诊断的中价值 较高，治疗随访中可依据病灶影像学征象 不同加以判断预后状况。

Objective To investigate the application value of MRI in the diagnosis and treatment follow-up of gliomas. Methods The clinical data of 32 patients with gliomas confirmed by surgery and pathology in our hospital between March 2008 and October 2011 were retrospectively analyzed. All cases were diagnosed by MRI, and the MRI manifestations and pathological types of the patients were observed. Patients were followed up after operation. The manifestations of MRI plain scan and enhanced scan were analyzed to explore the application value of MRI in the follow-up of gliomas after treatment. Results In32 cases, there were 18 casesof astrocytomas (including pilocytic astrocytoma, diffuse astrocytoma and glioblastoma etc.). 6 cases of oligodendrogliomas, 5 cases of ependymomas and 3 cases of choroid plexus papilloma. MRI imaging findings of various types of gliomas were different.After treatment, follow-up found that 18 cases showed reactive enhancement, 5 cases had residual tumor and 9 cases had recurrence, and the MRI manifestations were different. Conclusion MRI is of high value in the diagnosis of gliomas, and the prognosis of the patients can be judged according to the different imaging findings.
