摘要 目的探讨MRI弥散成像(DWI)、灌注成像(PWI)对急性脑梗死的诊断及治疗指导价值。方法发病<24h的急性脑梗死患者79例。立即行MRI常规检查及DWI,16例行PWI检查,14例接受尿激酶溶栓治疗为治疗组,其余65例为对照组。结果DWI对急性脑梗死的诊断率为100%,DWI、T2加权成像(T2WI)、T1加权成像(T1WI)对急性脑梗死诊断准确率为100%、50.6%、36.7%;有显著差异。治疗组治疗前及治疗后72h、3周神经功能缺损程度评分为35.3±3.8、15.7±2.4、12.5±1.6;对照组分别为38.3±3.2、25.7±2.9、19.5±2.6。两组治疗前后神经功能缺损程度评分比较有显著差异。结论DWI对急性脑梗死诊断具有明显优势,DWI与PWI联合应用判断缺血半暗带是否存在,对溶栓治疗有指导作用。超急性期溶栓治疗效果优于其它治疗。
