目的 确定ＣＴ扫描对皮层下动脉硬化性脑病（ＳＡＥ）的诊断价值。方法 对经临床ＣＴ确诊的８２ 例皮层下动脉硬化性脑病资料进行分析总结。结果 ＳＡＥ的ＣＴ表现特征为大脑深部白质内低密度区或累及脑室周围、半卵园中心、额、顶、枕叶等伴有不同程度脑萎缩和多发性脑梗塞。结论 ＣＴ不能直接显示脑小穿支动脉的硬化改变，但可以反映动脉硬化后的脱髓鞘及小梗塞灶，可解释患者临床损害，区别其他脑白质病变。
Objective To determine the value of CT scan in the diagnosis of subcortical arteriosclerotic encephalopathy (SAE). Methods The data of 82 cases of subcortical arteriosclerotic encephalopathy diagnosed by clinical CT were analyzed and summarized. Results The CT features of SAE were the low density of white matter in the deep part of the brain or the surrounding of the periventricular, the center of the semi-oval, and the amount of cerebral atrophy and multiple cerebral infarction in frontal, top and occipital lobe. Conclusion CT can not directly show the sclerosis of perforatorial artery, but it can reflect the demyelination and small infarction after arteriosclerosis. It can explain the clinical damage of patients and distinguish other white matter lesions.
