Background
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.
Methods
HRMR-VWI was performed on 5 patients who had been diagnosed with nonhemorrhagic vertebrobasilar
artery dissection.
Result
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.
Conclusion
HRMR-VWI is thought to elucidate the condition of the affected vessel wall more in
detail as compared with conventional methods.
