| 摘 要： | 目的探讨MR扩散加权成像(DWI)瘤周水肿区表观扩散系数(ADC)值在脑内肿瘤鉴别诊断中的价值。资料与方法82例脑肿瘤患者进行常规MRI扫描和DWI检查,对照分析病变的实质部分、周围水肿区的ADC值、相对表观扩散系数(rADC)值、指数表观扩散系数(EADC)值、相对指数表观扩散系数(rEADC)值。结果高级别胶质瘤与低级别胶质瘤、转移瘤、脑膜瘤、淋巴瘤的瘤周水肿ADC值、rADC值差异有统计学意义(P<0.05)。高级别胶质瘤与低级别胶质瘤瘤周水肿的EADC值、rEADC值差异有统计学意义。结论瘤周水肿区ADC值有助于高级别胶质瘤与其他脑内肿瘤鉴别,也可有助于胶质瘤分级。
