摘要 目的探讨1.5TMRI与MRA联合应用在Moyamoya病(MMD)诊断中的实用价值。方法按照1997年国际MMD诊断标准,选择临床拟诊经DSA诊断MMD30例,应用1.5T磁共振扫描仪行MRI和MRA检查,综合分析MMD临床表现、MR影像直接征象与间接征象。结果 30例MMD儿童组6例均为双侧,成人组24例中22例为双侧,另2例为单侧(变异型),共计58侧大脑半球脑底血管闭塞/狭窄,ICA床突上段15支,ACA20支,MCA35支,ICA15支,PCA6支,总计91支血管。轻度者(4例)双侧单支MCA或ACA受累,中度者(25例)双侧多支MCA、ACA、ICA受累,重度者(1例)在中度基础上单或双侧PCA也受累。DSA显示ICA床突上段闭塞/狭窄14/1例,ACA、MCA、PCA闭塞/狭窄分别为20/0、33/10、6/0例,颅内外侧支血管9例,烟雾血管30例。MR显示MMD直接征象有ICA床突上段闭塞/狭窄15/0例,ACA、MCA、PCA近段闭塞/狭窄分别20/0、35/8、5/1例,烟雾血管30例,颅内外侧支血管3例。MR间接征象有脑梗死14例(大面积脑梗死1例,腔隙脑梗死13例),脑出血15例,脑萎缩6例,脑软化7例,早期Ivy征象(常青藤征)1例。结论 MRA显示MMD直接征象与DSA相仿,但除外少数夸大狭窄血管程度及颅内外侧支血管显示稍显逊色,同时MRI也可满意显示MMD间接征象,MR对MMD是一种相当合理的影像检查方法,具有较重要临床实用价值。
