To assess the usefulness of evaluating basilar arterial flow by magnetic resonance angiography (MRA), MRA results for patients with vertebrobasilar insufficiency (VBI) were compared with those for age-matched individuals with no vestibular disorders. The presence of stenosis in the basilar artery, its severity and the presence of complications associated with atherosclerosis in the two groups were statistically compared. Analyses revealed significant differences in the incidence of stenosis, its severity, and the incidence of complications between the two groups. These findings suggest that MRA is valuable for the estimation of vertebrobasilar hemodynamics. MRA evaluation of basilar artery stenosis appears to be suitable for identifying a high-risk group among VBI patients, since basilar artery stenosis can result in serious disabilities.
为评估通过磁共振血管造影（MRA）评估基底动脉血流的实用性，将椎基底动脉供血不足（VBI）患者的MRA结果与年龄匹配的无前庭疾病个体的结果进行了比较。对两组基底动脉狭窄的存在情况、严重程度以及与动脉粥样硬化相关并发症的存在情况进行了统计学比较。分析显示两组在狭窄发生率、严重程度及并发症发生率方面存在显著差异。这些发现表明MRA对评估椎基底动脉血流动力学具有重要价值。对基底动脉狭窄进行MRA评估似乎适用于识别VBI患者中的高危人群，因为基底动脉狭窄可导致严重残疾。
