皮层下动脉硬化性脑病的MRI诊断

Value of MRI in diagnosis of subcortical arteriosclerotic encephalopathy

目的 探讨MRI对皮层下动脉硬化性脑病的特征和诊断价值。方法 采用轴位MRI扫描,部分病例加做冠状位扫描。结果 本组48例均见脑白质区改变和不同程度脑萎缩,42例可见腔隙性脑梗塞。结论对于50岁以上老年人,伴有不同程度痴呆,记忆力下降,言语不清,临床上难以明确诊断者,MRI最终能够确诊。

Objective To explore MRI features of the subcortical arteriosclerotic encephalopathy and to evaluate the value of MRI in diagnosis of the disease. Methods Fourty-eight patients with subcortical arteriosclerotic encephalopathy were diagnosed by axial MRI scans, some cases had coronal MRI scans. Results There were some changes in white matter including different degrees of cerebral atrophy in all 48 cases and lacu-nar infarction in 42 cases. Conclusion MRI should be applied to the people over 50-year -old who manifested the dementia in varying degrees, decrease of memory, and trouble of speech, for searching the definite diagnosis.
