皮层下动脉硬化性脑病的影像学诊断

目的 探讨皮层下动脉硬化性脑病（SAE）的影像学诊断价值。方法 选择经影像学检查结合临床资料确诊的病例，其中单做CT检查84例，单做MRI检查14例，既做MRI检查对照24例进行分析。另又对某一时期内60岁以上（不管什么原因）做头颅CT检查患者，只有2例有痴呆，CT分型Ⅰ型47例，Ⅱ型13例，Ⅲ型为24例；同一时期头颅CT检查患者中，有SAE表现42例，无SAE表现42例；24例CT与MRI检查对照。MRI优于CT。结论 CT与MRI检查可以对SAE作出早期诊断，有助于早期治疗。

Imaging diagnosis of subcortical arteriosclerotic encephalopathy

Objective To discuss the value of imaging assessment on sub-cortical arteriosclerotic encephalopathy (SAE). Methods 122 cases of SAEdiagnosed by imaging and clinical data were analyzed (including CTscanning 84 cases, MRI 14 cases and both of CT scanning and MRI 24cases).The cranial CT scanning data of the same period from other 84people (older than 60 years old) examined for whatever reasons were ascontrols. Results In the 84 patients of SAE diagnosed by CT scanning,47 patients were classified as type I,13 patients type II,and 24 patients typeIII, among whom only two people suffered from dementia.The SAE CTappearances were seen in 42 of 84 patients of the control group.In the 24patients received both of CT and MRI examination, the quality of MRIimaging was superior to that of CT. Conclusion CT and MRI is helpfulto the early diagnosis and treatment of SAE.
