目的 探讨MRI对高级别脑胶质 瘤的临床诊断价值。方法 回顾性分析 2013年1月-2015年12月期间接收并经手 术病理确诊的87例脑胶质瘤患者的MRI 检查资料，并对脑胶质瘤患者的病变部 位、与周围组织关系以及病变级别等MRI 影像特征进行综合分析。结果 87例患 者中诊断出星形细胞瘤56例，少枝胶质 瘤15例，9例室管膜瘤以及7例髓母细胞 瘤。根据WHO的脑胶质瘤等级划分原则， 以MRI影像特征为基础，对脑胶质瘤进 行等级划分，低级别脑胶质瘤9例，其 中I级3例，II级6例，高级别脑胶质瘤 78例，其中包括III级54例和23例IV级 患者。结论 MRI在脑胶质瘤的诊断过程 中，不仅能够定位诊断出肿瘤的发育部 位、大小、形态，还能通过综合分析胶 质瘤的MRI影像表现与病理特点进行定性 诊断其肿瘤类型以及级别，能很好的区 分低级别脑胶质瘤和高级别脑胶质瘤， 具有重要的临床应用价值，值得进一步 推广和应用。

Objective To investigate the clinical value of MRI in the diagnosis of highgrade gliomas. Methods Retrospective analysis of MRI data of 87 patients with gliomas confirmed by surgery and pathology in our hospital from January 2013 to December 2015. And comprehensive analysis of the lesion location, morphology and other MRI imaging features. Results Among 87 patients, there are 56 cases diagnosed with astrocytoma, 15 cases of less sticks glioma, 9 cases with ependymoma room and 7 cases of medulloblastoma. According to the WHO classification criteria of glioma, classifying the gliomas on the basis of MRI imaging features, there are 9 cases of low-grade gliomas, including 3 cases of grade I, 6 cases of grade II, 78 cases of high-level brain gliomas, including 54 cases of grade III and 23 cases of grade IV patients. Conclusion In the diagnosis of glioma, MRI not only diagnose tumor location, size, shape, but also determine the tumor type and grade through a comprehensive analysis of MRI imaging and pathological features, which can effectively distinguish low-grade gliomas and high-grade gliomas. It has important clinical value, which is worthy of further promotion and application.
