目的：探讨磁共振成像（MRI）和经颅多普勒（TCD）评价后循环缺血的价值。方法：对56例诊断为后循环缺血患者的临床资料进行回顾性分析。结果：头颅MRI发现脑干、小脑、枕叶梗死灶共46个;椎基底动脉磁共振血管造影显示达39例（69.6%）双侧椎动脉不对称、粗细不均,10例（17.9%）一侧椎动脉起始段不同程度狭窄,1例锁骨下动脉狭窄。TCD显示血流速度异常者40例（71.4%）,频谱异常36例（64.3%）。结论：MRI和TCD能给后循环缺血的诊断提供客观依据;MRI优于TCD。

Objective：To study the value of magnetic resonance imaging（MRI） and transcranial doppler（TCD） to evaluate posterior circulation ischemia.Methods：The retrospective analysis of clinical data of 56 cases with Posterior circulation ischemia.Results：It was found a total of 46 infarcted focuses in brain stem,Cerebellum,occipital lobe by head MRI examined.The abnormal vascular of vertebrobasilar artery by magnetic resonance angiography examined were 39 cases（69.6%） with asymmetric and various sized of bilateral vertebral arteries,10 cases（17.9%） with different degree stenosis of one side vertebral artery in initial segment,1 case with stenosis of subclavian artery.The abnormal vascular of TCD were 40 cases（71.4%） with the blood flow velocity,36 cases（64.3%）with abnormal spectrum.Conclusion：MRI and TCD could provide objective basis for clinical diagnosis of posterior circulation ischemia.MRI better than TCD.
