皮层下动脉硬化性脑病的CT评价

CT evaluation of subcortical arteriosclerotic encehalopathy

目的探讨早期皮层下动脉硬化性脑病(SAE)的CT诊断价值。方法选择无明显痴呆表现而在CT影像上有所发现的病例60例,经过3～10年的跟踪观察,采用简易智力状态检测量表(MMES)和CT检查,根据CT上脑白质低密度所累及的范围,将其分为轻、中、重度,总结该病的发展规律。结果随着随访年数的增加,CT表现由轻度变为中度、重度的病例不断增加,发生痴呆的患者所占的比例也增加。结论CT对SAE的发现和随访病变进展有重要意义。

Objective To explore the CT appearances of the Subcortical Arteriosclerotic Encehalopathy（SAE ）. Methods 60 cases of adult patients with positive signs on CT but no obvious dementia were selected into the study group and followed up by 3-10 years. They were assessed by the Minom Medica Education Society （MMES）and the brain CT scanning. In order to find the disciphne of SAE, they were divided into three stages： slight, moderate and severe stage by the range of alba low density on CT scan. Results The following-up time was longer, the cases whose positive CT signs were impaired more serious, and the dementia cases were also increased in number. Conclusion CT examination can he usd to evaluate SAE.
