Address and present prevalence of asymptomatic high parasellar flow on MRA in the literature and our institution Review origin of these incidental and false positive signs for dural arteriovenous fistulas (DAVFs), and illustrate MRA signs suggesting benignity, including modification of MRA presaturation pulses and use of 4D MRA, from our local experience Contrast with MRA signs indicative of aggressive DAVFs based on existing classification systems Formulate work-flow algorithm to manage the clinical conundrum and better select patients needing further 4D MRA or invasive angiography
