| 摘 要： | 目的:探讨64排螺旋CT血管造影在诊断烟雾病中的应用价值.材料与方法:分析12例烟雾病病例.其中男5例,女7例,年龄16～72岁.对受检者行颅脑CT平扫及CTA检查,采用容积再现(VR)、最大密度投影、多平面重建技术处理图像.结果:12例病人均见基底节区扩张的脑血管,即烟雾血管.其中9例颅内可见不同部位的出血灶.CTA可清晰显示狭窄、闭塞以及增多的脑血管.VR重建有利于显示病变血管与周围结构的空间关系,但在显示细小血管和侧支方面不如MIP和MPR.6例病人有DSA检查,DSA显示颈内动脉终末段或大脑前动脉、大脑中动脉近端闭塞以及基底节区增生血管网,病理血管分布与CT一致.结论:64排螺旋CT血管造影对诊断烟雾病有重要的应用价值.

| Abstract: | Objective: To study the value of 64-slice Spiral CT angiography in the diagnosis of Moyamoya disease.Material and methods: SCTA findings of 12 cases with Moyamoya disease were analyzed.In 12 cases,Male 5 and Female 7 were studied,age ranged from 16-72years.12 patients with Moyamoya disease were examined both with routine CT scanning and CTA,all performed Volume Rendering(VR),Maximum Intensity projection(MIP),Multi-planar(MPR).Results: Moyamoya vessels which were located in basal ganglia region.Cerebral hemorrhage was found in 9 cases.CTA showed the stenosis or occlusion of arteria and abnormal vessel network.VR was better on showing the stenosis of the vessels and its spatial relation with surrounding structure,MIP and MPR were better on showing abnormal vessel network in brain basal part and branch vessels.Stenosis or occlusion of the Distal portion of the ICA,Proximal portion of the ACA or MCA,and moyamoya vessels of basal ganglia region were demonstrated by DSA(n=6).Conclusion:64-slice Spiral CT is of great value in the diagnosis of Moyamoya disease. |
