To estimate the usefulness of magnetic resonance imaging (MRI) in diagnosing vertebro-basilar insufficiency (VBI), 41 VBI patients with vertigo or dizziness and 26 subjects without vertigo or dizziness (as control) were examined by MRI. Sixty-eight percent of the VBI group and 12% of the control group showed a large difference between the right and the left vertebral artery diameter, the incidence being significantly higher in the VBI group. Thirty-nine percent of the VBI group and 12% of the control group had lacunar infarction in the brain stem, of which the incidence was significantly higher in the VBI group, MRI can be recommended to diagnose VBI providing information on both blood vessel disorder and ischemic changes in the brain.
为评估磁共振成像（MRI）在诊断椎基底动脉供血不足（VBI）中的作用，对41例有眩晕或头晕症状的VBI患者及26例无眩晕或头晕症状的受试者（作为对照）进行了MRI检查。VBI组68%以及对照组12%的患者左右椎动脉直径存在较大差异，VBI组的发生率显著更高。VBI组39%以及对照组12%的患者脑干有腔隙性梗死，其中VBI组的发生率显著更高。MRI可用于诊断VBI，它能提供血管病变及脑部缺血性改变两方面的信息。
