皮层下动脉硬化性脑病的MRI诊断

目的：探讨皮层下动脉硬化性脑病的MRI诊断价值。材料和方法：分析64例皮层下动脉硬化性脑白质病的MRI表现，并与34例CT结果比较。结果：该病的MRI表现为侧脑室前后角及体部周围对称性月晕状长T1长T2信号，临床分析高血压占67％，痴呆占43％，多发性脑梗塞占84％。结论：MRI为诊断皮层下动脉硬化性脑病的主要影像学方法之一。

MRI Diagnosis of Subcortical Arteriosclerotic Encephalopathy

Purpose: To study the diagnostic value of MRI in subcortical arteriosclerotic encephalopathy. Materials and Methods: The MRI findings of 64 cases of subcortical arteriosclerotic encephalopathy were analyzed and compared with the CT results in 34 cases. Results: The imaging features of subcortical arteriosclerotic encephalopathy were peripheral symmetric halo signal on long T1 and long T2 in cornu anterius ventriculi lateralis, cornu posterius verticuli lateralis and pars centralis. The clinic analysis were: hypertension 67%, senile dementia 43%, cerebral polyinfarction 84%. Conclusion: MRI is one of the best methods for the diagnosis of subcortical arteriosclerotic encephalopathy.
