摘　　要：目的观察并分析后循环缺血性眩晕采取磁共振动脉成像(MRI)的效果及实践价值。方法选取2020年1月~2022年1月于我院就诊的经病理结果证实的后循环缺血性眩晕患者研究,总计62例,对所有病例施行CT、MRI检查,评价不同方法于后循环缺血性眩晕中的诊断效果,分析磁共振动脉成像状况、基底动脉血供不充足分型及双侧椎动脉血供不充足测定状况。结果①不同方法诊断准确率:相比CT,MRI诊断准确率表现更高,差异有统计学意义(P<0.05);②基底动脉血供不充分分型测定状况:A/B/C型占据比例分别为67.74%(42/62)、14.52%(9/62)、14.52%(9/62),A型并发B型变化占据比例为1.61%(1/62),无异常占据比例为1.61%(1/62);③双侧椎动脉血供不充足测定状况:A/B/C/D型占据比例分别为57.84%(68/124)、8.06%(10/124)、10.48%(13/124)、10.48%(13/124),A型并发B型变化占据比例为10.48%(13/124),B型并发C型变化占据比例为4.03%(5/124),无异常占据比例为1.61%(2/124)。结论后循环缺血性眩晕采取MRI诊断效果优于CT,其可对基底动脉、双侧椎动脉血供状况予以有效反映,评估脑灌注状态,降低漏诊及误诊,具较高的诊断价值。Objective To observe and analyze the effect and practical value of magnetic resonance angiography(MRI)in patients with posterior circulation ischemic vertigo.Methods From January 2020 to January 2022,62 patients with posterior circulation ischemic vertigo were examined by CT and MRI,to evaluate the diagnostic efficacy of different methods in posterior circulation ischemic vertigo,and analyze the status of magnetic resonance angiography(MRA),classification of basilar artery insufficiency and measurement of bilateral vertebral artery insufficiency.Results The diagnostic accuracy of different methods:compared with CT,MRI showed higher diagnostic accuracy,the difference was statistically significant(p<0.05);@The percentage of type A/b/C was 67.74%(42/62),14.52%(9/62),14.52%(9/62),respectively.The percentage of type a complicated with type B was 1.61%(1.62);③The ratio of A/b/c/D was 57.84%(68/124),8.06%(10/124),10.48%(13/124),10.48%(13/124),respectively,the rate of type a complicated with type B change was 10.48%(13/124),type B complicated with Type C change was 4.03%(5/124),and the rate of no abnormality was 1.61%(2/124).Conclusion MRI is better than CT in the diagnosis of posterior circulation ischemic vertigo,it can reflect the blood supply of basilar artery and bilateral vertebral artery effectively,evaluate the cerebral perfusion,reduce the missed diagnosis and misdiagnosis,it has high diagnostic value.
