目的 探讨CT血管造影(computed tomography angiography, CTA)、三 维动态增强磁共振血管成像(threed i m e n s i o n a l d y n a m i c c o n t r a s t enhanced MR angiography, 3D-CEMRA)对 颈性眩晕的诊断价值及影像学表现。方 法 回顾性分析2014年5月至2016年5月医 院收治的100例颈性眩晕患者的影像学资 料，包括CT、CTA、MRI、3D-CEMRA。结果 CTA诊断显示阳性率为88.0%，与3D-CEMRA 的87.0%比较，差异无统计学意义(P＞ 0.05)。CTA扫描显示57例出现椎-基底动 脉动脉变细或迂曲，部分末段显示不清； 23例出现钩椎关节增生、发育不良等； 3D-CEMRA显示58例椎-基底动脉动脉狭窄 或迂曲，10例伴随椎-基底动脉轻度移位- 扭曲，29例出现椎间失稳、钩椎关节增生 等。结论 CTA、3D-CEMRA是诊断颈性眩晕 的重要、无创影像学手段。

Objective To explore the diagnostic value and imaging features of CT angiography (CTA) and three-dimensional dynamic enhancement magnetic resonance vascular imaging (3D-CEMRA) for cervical vertigo. Methods A retrospective analysis of imaging data was carried out in 100 patients with cervical vertigo treated in our hospital from May 2014 to May 2016, including CT, CTA, MRI, 3D-CEMRA. Results There was no significant difference in the detection rate of positive between CTA (88.0%) and 3D-CEMRA (87.0%) (P>0.05). CTA scan showed that 57 cases of vertebral-basilar artery artery thin or tortuous, part of end-piece display was not clear, 23 cases with hyperplasy and cacoepy of uncovertebral joint, 3D-CEMRA showed that 58 cases of vertebral-basilar artery narrow or tortuous, 10 cases were complicated with vertebralbasilar artery slight shift-angulation, 29 cases with intervertebral destabilization and hyperplasy of uncovertebral joint. Conclusion CTA and 3D-CEMRA are important and non-invasive imaging technologies for the diagnosis of cervical vertigo.
