摘　　要：目的　探讨头臂动脉型多发性大动脉炎的MR表现特点。方法　回顾性分析经临床诊断为头臂动脉型多发性大动脉炎的 10例MRI和动态增强MRA表现。 10例中的 4例同时行血管造影 ,2例行彩超检查。结果　 10例MRI检查共显示血管狭窄、闭塞 46个节段 ,与血管造影、彩超对照比较 ,两者符合率 >70 %。结论　MRITSE序列和动态增强MRA的联合应用 。Objective To make a further understanding of MRI manifestations in Takayasu's arteritis of pulseless disease. Metheds 10 patients with Takayasu's arteritis of pulseless disease confirmed by clinical materials,were performed TSE sequence and dynamic contrast enhanced MRA,4 patients did additional conventional angiography and 2 patients did additional color Doppler ultrasound. Results MRI showed 46 segments of arterial stenosis or occusions.In comparison with angiography or color ultrasound,the accordance rate of MRI was>70%. Conclusion With combined application of MRI and dynamic contrast enhanced MRA, Takayasu's arteritis of pulse disease can be clearly showen and identified.
