摘要 目的 :探讨老年人脑白质病变 (White Matter L esion,简称 WML )的 MRI表现及其临床意义。方法 :采用 MRI SE序列对 82例老年人 WML进行颅脑 MRI检查 ,评估其 MRI表现及其临床意义。结果 :老年人 WML的MRI主要表现是脑白质内点状及斑片状信号异常 ,以 T2加权像改变为明显。病变分为腔隙性脑梗塞或 /和腔隙病变、脑白质稀疏症、皮层下动脉硬化性脑病 (subcortical arterosclerotic encephalopathy,简称 SAE)等几种类型。 WML病变常见于患有高血压和高脂血症的患者 ,临床上可无症状 ,也可表现为神经、精神的异常。结论 :老年人 WML以腔隙性脑梗塞和腔隙病变最多见 ,SAE少见 。
