This study compared high-resolution vessel wall imaging (HR-VWI) and time-of-flight magnetic resonance angiography (TOF-MRA) for evaluation of stenosis using digital subtraction angiography (DSA) as the criterion standard. Compared with TOF-MRA, HR-VWI produced results that more closely agreed with DSA, showed better reproducibility and accuracy with smaller variance, and provided additional information on vessel wall pathology. HR-VWI may therefore be useful as an adjunct to DSA to diagnose stenosis and evaluate changes in intracranial vessel walls.
