Vessel Wall Imaging of Cerebrovascular Disorders
Purpose of review
High-resolution magnetic resonance vessel wall imaging (VWI) permits direct visualization of intracranial arterial wall pathology, providing diagnostic and prognostic information that is complementary to conventional imaging techniques. We highlight the most recent studies that have advanced the clinical application of VWI.
VWI aids in distinguishing and diagnosing intracranial atherosclerotic disease (ICAD), intracranial dissections, central nervous system vasculitis, reversible cerebral vasoconstriction syndrome, and moyamoya disease. VWI may help predict recurrent stroke in ICAD, treatment effects in vasculitis, and disease progression in moyamoya. VWI also identifies ruptured intracranial aneurysms and may predict stability of unruptured aneurysms.
Implementing VWI as an adjunctive imaging technique may permit earlier and noninvasive discrimination of rare vasculopathies. However the prognostic utility of VWI for more common cerebrovascular pathologies requires further validation.

This Korean study used VWI to evaluate acute stroke patients with focal, intracranial stenoses of unclear etiology and identified more than one third as intracranial dissections by their imaging criteria. Compared with atherosclerotic lesions, patients with dissections had similar 90-day outcomes, but were less likely to have recurrent events and more likely to have improvement in the focal stenosis on follow-up imaging.CrossRefPubMedPubMedCentralGoogle Scholar
