低场MRI对皮层下动脉硬化性脑病的诊断价值

目的探讨皮层下动脉硬化性脑病低场MRI表现及诊断价值。方法回顾性分析32例经临床及低场磁共振检查确诊的皮层下动脉硬化性脑病患者,全部患者均进行常规T1WI、T2WI、FLAIR序列检查。结果 MRI表现为侧脑室前后角、体部周围、放射冠、半卵圆中心片状稍长T1、长T2异常信号,FLAIR序列病灶表现为高信号,其中Ⅰ型7例、Ⅱ型10例、Ⅲ型15例。可伴发脑萎缩或腔隙性脑梗塞,有的可伴发脑出血。结论 MRI是SAE首选影像学检查方法,低场MRI可用于SAE的诊断。

Value of low-field MRI in the diagnosis of subcortical arteriosclerotic encephalopathy

Objective To investigate to the features and diagnostic value of Subcortical Arteriosclerotic Encephalopathy（SAE） by lowfield MRI.Methods Retrospective analysis of 32 cases of clinically and low field MRI of the brain diagnosed patients with SAE,all patients were routine T1WI,T2WI,FLAIR sequence inspection.Results MRI Patches-like slight long T1 and long T2 signal areas could be seen around frontal,occipital horn and body of the lateral ventricle、corona radiate、Centrum semiovale、lesions showed the high signal in FLAIR,including 7 patients of first type 10 patients of second type and 15 patients of third type complicated with the sign of lacunar infarction,cerebral atrophy,parenchymal hemorrhage in some cases.Conclusion MRI can be considered as the best examination of SAE,and low-field MRI can be used for SAE diagnosis.
