摘要
目的:探讨脑白质疏松(leukoaraiosis,LA)的磁共振表现。方法:结合患者临床表现及磁共振检查,参照Fazekas量表,对60例有急性小动脉病变性脑梗死(small artery disease,SAD)和60例没有急性小动脉病变性脑梗死的LA患者按照解剖学部位进行分型,并分析其意义。结果 :存在SAD的60例LA患者中,脑室周围型36例(60%),皮质下型12例(20%),混合型12例(20%);不存在SAD的60例LA患者中,脑室周围型10例(17%),皮质下型10例(17%)混合型40例(67%)。结论:多种因素会引起LA,LA的出现应作为脑血管病的前奏,应采取积极有效的干预措施,对预防老年痴呆也有重要意义。
Objective: To investigate the leukoaraiosis(leukoaraiosis, LA) magnetic resonance imaging. Methods: With the clinical and MRI examination, according to the Fazekas scale, the acute cerebral arteriolar lesion in 60 cases(small artery disease, SAD) no acute arterial lesions in cerebral infarction and 60 cases of LA patients were classified according to the anatomical site, and analyzes its significance. Results: There were 60 cases of LA patients with SAD, periventricular type in 36 cases(60%), subcortical type in 12 cases(20%), 12 cases of mixed type(20%); there are no 60 LA patients with SAD, 10 cases(17%), periventricular and subcortical type in 10 cases(17%) 40 cases of mixed type(67%). Conclusion: Many factors may cause LA, LA appears as a prelude to cerebrovascular disease, should take active and effective intervention measures, also has an important significance for preventing senile dementia.
