Brain arteriovenous malformations (bAVM) are congenital lesions detected incidentally or following symptomatic events like hemorrhage, seizure or headache. In bAVM patients, the most feared complication is intracranial hemorrhage with a general risk ranging between 2-4%1 and further functional and hemodynamic characterization of bAVMs may improve risk assessment and ultimately aid in patient management2, 3. In this study, bAVMs have been investigated using quantitative susceptibility mapping and phase contrast based flow measurements. Susceptibility across the bAVM nidus is studied in relation to flow characteristics.
