摘　　要：目的探讨VG、VGW及EI在术前评估脑胶质瘤级别中的作用。材料与方法搜集565例脑胶质瘤患者MRI影像资料,所有病例均经手术和病理证实。测量相应数值,计算VG、VGW以及EI值。采用SPSS 19.0软件进行数据处理,对照病理结果,对幕上高、低级别脑胶质瘤的VG、VGW、EI值进行比较做统计学分析;分别对高、低级别脑胶质瘤8个分区的VG、VGW、EI值两两分区进行比较做统计学分析。结果 (1)高级别脑胶质瘤的VG、VGW及EI值均大于低级别脑胶质瘤。(2)同等级别脑胶质瘤的VG、VGW的大小与肿瘤生长部位有关。(3)同等级别脑胶质瘤,发生在不同部位肿瘤的EI值的差异不具有统计学意义。结论 (1)肿瘤的恶性程度越高,VG、VGW及EI值越大。(2)同等级别脑胶质瘤,分布在血供丰富区的VG、VGW越大,且低级别胶质瘤差异性更显著。(3)同等级别脑胶质瘤EI值与肿瘤血供情况无关。Objective： Analyse the VG, VGW and EI to explore the role in the preoperative evaluation of cerebral glioma grade. Materials and Methods： Five hundred and sixty-five cerebral glioma patients pathologically confirmed were examinated by head conventional MRI during several years. Result：（1） The VG, VGW and EI of high grade cerebral glioma were higher than those of low grade cerebral glioma. （2） The VG and VGW of the same grade cerebral glioma were related to the tumor location. （3） The EI of same grade cerebral glioma had nothing to do with the tumor location. Conclusions：（1） The VG, VGW and EI of high grade cerebral glioma were higher than those of low grade cerebral glioma, and they increased with the growth of malignant degree. （2） The VG and VGW of the same grade cerebral glioma were related to the tumor location. And the difference of low grade glioma in different parts is more signiifcant. （3） The EI of same grade cerebral glioma had nothing to do with the tumor location.
