MRI影像分析在高级别脑胶质瘤鉴别诊断中的应用

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。

Study of the Value of MRI in the Diagnosis of High-Grade Gliomas

Objective To investigate the clinical value of MRI in the diagnosis of high-grade 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.
