磁共振血管造影和经颅多普勒超声对椎基底动脉供血不足的诊断价值

摘要

目的 探讨椎动脉磁共振血管造影(MRA)、经颅多普勒超声(TCD)对椎基底动脉供血不足(VBI)的临床诊断价值.方法 对临床确诊40例VBI患者的椎动脉MRA及TCD的检查资料进行分析,比较两种检查方法 在椎基底动脉供血不足中的诊断价值.结果 VBI患者TCD的阳性率为92.5%,椎动脉MRA的阳性率为62.5%.结论 椎动脉MRA与TCD的联合检查对VBI的病因诊断有较大的诊断价值.%Objective To explore the diagnostic value of magnetic resonance angiography(MRA)and transcanial doppler(TCD)in patients with vertibrobasilar insuffieiency(VBI).Methods MRA and TCD were performed in 40 patients with VBI.Results The nonnalitv rate of MRA and TCD was 92.5%and 62.5%respectively.Conclusion The combination use of MRA and TCD is helpful to diagnose VBI at early stage.
