We present a virtual catheter-based like post-processing procedure applied to 4D Flow MR Imaging to obtain a non-invasive MR complete characterization of brain vascular malformations. We compared this MR selective flow-tracking cartography procedure to catheter-based cerebral intra-arterial digital subtraction angiography (DSA). This technique was successfully performed in 10 patients with brain arteriovenous malformations or dural arteriovenous fistulas. There was a high agreement between DSA and MR cartography in the definition of the main feeding arteries and draining veins. MR selective flow-tracking cartography of fistulas allowed to obtain a Cognard MR classification consistent with DSA. These results suggest that MR selective cartography is a promising alternative to DSA in the diagnosis and follow-up of brain vascular malformations.
