| 摘 要： | 目的探讨磁共振扩散成像(DWI)联合表观弥散系数(ADC)对脑肿瘤鉴别诊断的价值。方法选取2012年5月至2018年2月间西安市第四医院收治的81例实施磁共振检查的脑部分肿瘤患者,均行头颅MRI常规平扫、常规增强扫描及DWI联合ADC检查。比较良恶性脑肿瘤间、肿瘤侧与对照侧间及高低级别脑胶质瘤间的DWI信号强度和ADC值,比较DWI信号强度、ADC值及DWI联合ADC对恶性脑肿瘤的诊断灵敏度、特异度和准确度。结果当b=400s/mm^2、600s/mm^2和1 000s/mm^2时,恶性组患者DWI信号强度高于良性组,ADC值低于良性组,高级别组患者DWI信号强度高于低级别组,ADC值低于低级别组,差异均有统计学意义(均P <0. 05)。良性组和恶性组的DWI信号强度均高于对照组,ADC值均低于对照组,差异均有统计学意义(均P <0. 05)。DWI联合ADC的灵敏度、特异度和准确度均高于DWI信号强度和ADC值诊断(P <0. 05);DWI信号强度和ADC值诊断效能比较,差异无统计学意义(P> 0. 05)。结论 DWI信号强度和ADC值可用于鉴别脑肿瘤的良恶性及高、低级别胶质瘤,而取不同b值时得到不同的DWI信号强度和ADC值,且DWI联合ADC可明显提高DWI信号强度和ADC值对脑肿瘤的诊断效能。
