CT、MRI和磁共振动脉成像对后循环缺血性眩晕的诊断价值

CT,MRI and Magnetic Resonance(NMR) Artery Imaging Diagnostic Value of Posterior Circulation Ischemic Vertigo

目的探讨后循环缺血性眩晕采用CT、MRI和磁共振动脉成像诊断价值。方法方便选取后循环性眩晕患者60例,均为该院神经内科或耳鼻咽喉科2015年4月—2016年4月收治,行CT、MRI和磁共振动脉成像检查。采用CT对脑梗死进行检查时结果呈阳性,不存在脑梗死病变的则呈阴性。而采用MRI对脑实质病变检查时结果呈阴性,不存在脑实质病变的才呈阳性。结果该次选取的60例患者,采用CT检查,阳性16例,占26.7%;阴性44例,占73.3%。MRI检查,阳性46例,占76.7%,阴性14例,占23.3%,故差异有统计学意义(P<0.05)。基底动脉A型42条,B型、C型分别4条,无异常2条,A型合并B型改变2条。结论后循环缺血性眩晕采用磁共振检查,可为确诊提供有力的参考依据,值得在临床广泛应用。

Objective To investigate the value of CT, MRI and magnetic resonance imaging in the diagnosis of Posterior Circulat ion Ischemia Vertigo. Methods C onvenient selection 60 cases of posterior circulation vertigo were selected , all of which were admitted to our hospital from April 2016 to April 2015. The patients were treated with CT, MRI and magnetic resonance imaging. CT was positive in the examination of cerebral infarction, and there was no negative cerebral infarction. And the results were negative when MRI was used for the examination of brain parenchymal lesions, and there was no brain parenchymal lesions. Results The selected 60 patients, using CT examination , 16 cases were positive, accounting for 26.7% ; negative in 44 cases , account ing for 73.3%. MRI examination, 46 cases were positive, account ing for 76.7%, negative in 14 cases, account ing for 23.3%, so with statistical difference （P〈0.05）. Basilar artery type A 42, type B, type C were 4, no abnormal 2, A type combined with type B change 2. Conclusion Posterior Circulation Ischemia Vertigo using magnetic reso-nance examination, can provide a powerful reference for diagnos is , it is worth in clinical widely used.
