MRI has an important role in categorizing vascular malformations as low-flow or high-flow and determining their extent. TWIST is a high temporal resolution time resolved MRA technique which potentially allows for differentiation of flow states. Five patients with vascular malformations were examined with at 3T with TWIST and standard ceMRA. The introduction of the TWIST sequence increased ability to characterize flow patterns related to the malformation as compared to ceMRA and greatly helps in treatment planning.
