Digital subtraction angiography (DSA) is the golden standard of radiological technique for diagnosis and treatment evaluation of cerebral arteriovenous malformations (CAVMs). However, DSA is invasive and ionizing radiative. Silent MRA, which combines arterial spin labeling (ASL) and an ultrashort time echo (UTE), is used for CAVM structure visualization. The silent MRA is superior to TOF-MRA and enables the same Spetzler-Martin classification of cerebral AVM as that at DSA.
