摘要
目的 :探讨螺旋CT(spiralCT ,SCT)和螺旋CT血管造影 (spiralCTangiography,SCTA)对Moyamoya病的诊断价值。方法 :回顾性分析 10例Moyamoya病患者的SCTA表现。其中男 4例女 6例 ,年龄 9岁～ 4 2岁 ,其中 14岁以下者 7例 ,应用PickerSeleSp螺旋CT扫描仪行常规SCT平扫 ,然后采用螺旋CT扫描方式进行SCTA原始图像数据采集 ,其中 3例有DSA ,6例有MRI,另外随机选择 10例SCT和SCTA正常者作为对照组。结果 :10例病人横断面均见丘脑基底节区扩张的脑血管 ,即烟雾血管。 10例SCTA和 3例DSA显示颈内动脉 (ICA)上段或大脑中动脉 (MCA) ,大脑前动脉 (ACA)近端闭塞以及丘脑基底节区Moyamoya血管 ,这些病理血管分布与SE序列MRI一致 ,对照组均见不到丘脑基底节区正常细小的穿支血管。结论
Objective:To explore the diagnostic value of spiral CT( SCT )and spiral CT angiography(SCTA)for Moyamoya disease .Methods:SCTA findings of 10 cases with Moyamoya disease were retrospectively analyzed .In 10 cases , Male 4 and Female 6 were studied,age ranged from 9-42 years,among which,7 cases were less than 14 years old .Noncontrast SCT and SCTA were carried with SeleSp Spiral CT (picker),We got the data of rescue image as Spiral CT scan with MRA study in 6 cases and DSA in 3 cases. Meanwhile there were 10 normal SCT and SCTA cases studied as a control group.Results: Low density Moyamoya vessels which were located in thalamus-basal ganglia region (3 unilateral and 7 bilateral ) stenosis or occlusion of the bifurcation of ICA ,Proximal portion of the ACA or MCA ,and moyamoya vessels of thalamus basal ganglia region were demonstrated by SCTA (n=10),and DSA (n=3). Normal perforating arteries of thalamus-basal ganglia region couldn't be seen obviously on SCT and SCTA in a control group .Conclusion: SCTA is an effective noninvasive method for the diagnosis of Moyamoya disease.
