摘要 目的 :探讨急性腔隙性脑梗死患者的脑部磁共振扩散加权成像 (MRDWI)表现及其ADC值变化。方法 :搜集急性脑梗死病例 5 4例 ,根据MRI显示病灶的位置、形态和最大直径 ,分为急性腔隙性脑梗死组 ( 3 9例 )和急性大面积脑梗死组 ( 15例 )。选正常对照组 5例。结果 :3 9例急性腔隙性脑梗死病例均有不同程度MRDWI表现 ;其ADC值与急性大面积脑梗死组之间差异无显著性意义。结论 :MRDWI对急性腔隙性脑梗死的诊断具有很好的敏感性和特异性 。 Objective:To evaluate acute lacunar infarct with diffusion weighted imaging and the ADC values.Methods:54 patients with acute infarct underwent MRI examination, including T 1WI,T 2WI and DWI.The patients were divided into two groups (group 1 of acute lacunar infarct,n=39;group 2 of acute large area infarct,n=15),5 patients with normal brain were also studied as a control group.Results:39 patients with acute lacunar infarct were well diagnosed by DWI and the ADC values,which were not significantly different from that of the acute large area infarct.Conclusion:Acute lacunar infarct can be well diagnosed by DWI and ADC values.
