High-resolution magnetic resonance vessel wall imaging (HRMR-VWI) has been used to explore vascular diseases such as vasculitis and vulnerable plaque of intracranial arteries. Although vessel wall inflammation is suspected as one of the causes of cerebral arterial dissection, there have been few reports regarding the application of HRMR-VWI to arterial dissection. We have therefore evaluated the efficacy of HRMR-VWI in patients with vertebrobasilar artery dissection.
HRMR-VWI was performed on 5 patients who had been diagnosed with nonhemorrhagic vertebrobasilar artery dissection.
Four patients exhibited vessel wall enhancement on HRMR-VWI, the range of which corresponded with the dissection sites identified by cerebral angiogram, magnetic resonance imaging, or magnetic resonance angiography. The enhancements observed in all cases were extensive as compared with the findings of conventional angiography.
HRMR-VWI is thought to elucidate the condition of the affected vessel wall more in detail as compared with conventional methods.
高分辨率磁共振血管壁成像(HRMR-VWI)已被用于探索血管疾病,如血管炎和颅内动脉易损斑块。尽管血管壁炎症被怀疑是脑动脉夹层的原因之一,但关于HRMR-VWI在动脉夹层中的应用报道较少。因此,我们评估了HRMR-VWI在椎基底动脉夹层患者中的疗效。
对5例被诊断为非出血性椎基底动脉夹层的患者进行了HRMR-VWI检查。
4例患者在HRMR-VWI上表现出血管壁强化,其范围与脑血管造影、磁共振成像或磁共振血管造影所确定的夹层部位相对应。与传统血管造影的结果相比,所有病例中观察到的强化范围都很广泛。
与传统方法相比,HRMR-VWI被认为能更详细地阐明受影响血管壁的状况。
