ABSTRACT
Proper characterization of an arteriovenous malformation (AVM) requires high spatial and high temporal resolution imaging. Although selective and super-selective arteriography fulfills these imaging requirements, the advantages of noninvasive methodologies such as ultrasound and combined magnetic resonance imaging and in rare cases computed tomographic angiography are being used to define the strategic management in AVM. Conventional arteriography remains an important invasive confirmer of AVM hemodynamics before starting the actual treatment. New image processing techniques are on the horizon aiming to better characterize AVM type and response to treatment.
