摘要
目的探讨MRI和MRA对儿童烟雾病（Moyamoya）的诊断价值。方法分析19例烟雾病患儿的MRI、MRA表现和临床资料。MRA采用3D TOP法，7例行增强MRA。结果MRI表现为①Moyamoya血管（双侧、19例）；孕大脑半球皮质和／或皮质下梗死、软化灶（14例）；③局部脑萎缩（10例）。MRA表现为颈内动脉虹吸部末端和大脑前或中动脉近端狭窄或闭塞，并有脑底部异常血管网形成。结论MRI和MRA是诊断烟雾病有效非创伤性的检查方法。MRI与MRA相结合可作为儿童烟雾病诊断的首选方法。
Objective To evaluate MRI and MRA in the diagnosis of moyamoya disease in children. Methods MRI and MRA findings and clinical materials of 19 patients with moyamoya disease in children were retrospectively analyzed. While 3D TOP was used for MRA. Enhanced MRA was carried out in 7 cases. Results MRI showed ①moyamoya vessels,bilateral（19cases） ;②the cortical and subcortical infarction and softening lesions（14 cases） ;and③local brain atrophy（10 cases）, MRA showed：Stenosis or occlusion at the terminus of the siphon portions of internal carotid arteries （ICA） and anterior cerebral arteries or middle cerebral arteries （ACA or MCA） ,and abnormal vascular networks at the base of brain were noted by MRA. Conclusion MRI and MRA are effective and noninvasive methods for the diagnosis of moyamoya disease. MRI combined with MRA may be used for the diagnoses of moyamoya disease.
