摘　　要：目的探讨MRI在后循环缺血性眩晕诊断中的作用。方法采用GE公司Signa Excite 3.0 T超导MRI设备,对75例后循环缺血性眩晕患者的MRI和磁共振血管成像(magnetic resonance angiography,MRA)检查结果进行回顾性分析,并按照不同的影像学表现将其分类。结果 75例血管性眩晕患者当中单纯椎基底动脉血管病变52例,占69%;合并梗死23例,占31%;50岁以上的患者为64例,占85%。各年龄段中引起眩晕的后循环缺血性疾病构成差异有统计学意义(χ2=10.171,P<0.05)。结论 MRI技术是后循环缺血性眩晕最常见病因的重要筛选工具,对诊断、治疗及判断预后有重要价值。OBJECTIVE To explore the value of magnetic resonance imaging on posterior circulation ischemic（PCI）vertigo.METHODS The imaging data about magnetic resonance imaging（MRI） and magnetic resonance angiography（MRA）of 75 patients with PCI vertigo were retrospectively analyzed.RESULTS Simple function change of vertebrobasilar artery lesions was found in 52 cases（69%）.The patients older than 50 years were found in 64 cases（85%）.There was significant difference in the causes of vertigo among the different age groups（χ 2=10.171,P 0.05）.CONCLUSION MRI plays an important role in diagnosis,treatment and prognosis of PCI vertigo.
