摘要
目的:分析和讨论烟雾病的MRI和MRA表现及其诊断意义。材料和方法:对9例烟雾病患者进行了MRI和MRA检查,其中2例进行了DSA检查。结果:9例MRI上,8例显示脑实质改变包括脑梗死5例,脑萎缩2例,脑室扩大1例。8例中4例显示异常血管流空现象。另1例脑内未见异常。MRA均良好地显示了病变血管狭窄和闭塞现象,表现为多支、双侧受累,以大脑中动脉为主,与DSA所见相仿。结论:MRI结合MRA可作为烟雾病诊断的首选检查方法。
Purpose: To analyze and discuss MRI and MRA manifestations of moyamoya disease.Materials and Methods: 9 patients with moyamoya disease were studied with MR imaging and three - dimensional time of flight(3D - TOF) MR angiography , two of whom were examined with DSA. Results: On MRI , brain abnormals were showed in 8 cases including brain infarction(5 cases) 3 brain atrophy(2 cases) 3 wided ventricles(1 case), and flow effect of basal ganglia moyamoya vessels(4 cases). Multiple cerebral vessels occlusion and stenosis can be well demonstrated on MRA. Conclusion: MRI and MRA has become a first choice method for diagnosis of moyamoya disease.
