摘要 目的探讨血管性痴呆(VaD)临床与MRI表现之间的关系。方法对比分析29例(VaD)患者和23例中风后非痴呆(SWD)者的MRI表现。结果VaD组中额叶、内囊前肢、尾状核、半卵圆中心前部、侧脑室体旁前部白质及丘脑梗死发生率、平均梗死灶数目及平均梗死灶体积均大于SWD组(P<0.05);3、4级脑白质疏松(LA)出现率显著高于对照组(P<0.05);脑室脑比率明显大于对照组(P<0.001)。多元统计分析,侧脑室体旁白质梗死体积、额叶梗死灶数目、丘脑梗死数目及LA是VaD的相关危险因素。结论VaD与侧脑室体旁前部白质梗死体积、额叶梗死数目、丘脑梗死数目及LA密切相关。MRI对VaD有辅助诊断作用。
