Vertebrobasilar haemodynamics correlate closely with syndromal vertigo. The aim of this study is to examine the clinical value of MRA for evaluation of vertebrobasilar haemodynamics in vertiginous patients. We examined 40 individuals (20 with vertebrobasilar insufficiency and 20 diagnosed with other vestibular disorders). MRA results were quantified on the basis of the severity of vascular stenosis in the major arteries of the vertebrobasilar system and we analysed the relationship of these results with otoneurological diagnoses, eye-tracking tests (ETT) and optokinetic nystagmus (OKN). MRA results correlated well with otoneurological diagnoses and ETT results. Consequently, MRA can be used as a screening examination to evaluate vertebrobasilar haemodynamics and ETT may be a sensitive functional parameter of vertebrobasilar insufficiency.
椎基底动脉血流动力学与综合征性眩晕密切相关。本研究的目的是探讨磁共振血管造影（MRA）在评估眩晕患者椎基底动脉血流动力学方面的临床价值。我们检查了40例个体（20例椎基底动脉供血不足患者和20例诊断为其他前庭疾病的患者）。根据椎基底动脉系统主要动脉血管狭窄的严重程度对MRA结果进行量化，并分析这些结果与耳神经学诊断、眼动跟踪测试（ETT）和视动性眼震（OKN）之间的关系。MRA结果与耳神经学诊断和ETT结果密切相关。因此，MRA可作为一种筛查检查来评估椎基底动脉血流动力学，而ETT可能是椎基底动脉供血不足的一个敏感功能参数。
