Low-flow Vascular Malformations (VMs) can present with a myriad of symptoms and signs, including pain, cosmetic disfigurement, functional impairment and bleeding. Current interventional radiologic techniques for treating low-flow VMs consists of using Ultrasound and X-ray angiography to access and treat these lesions percutaneously. Due to poor ultrasound penetration and repeated exposure to ionizing radiation, these modalities have significant limitations, which can be solved using real time MR guidance for these procedures. In this abstract we present our initial experience (including workflow, therapeutic agents and outcomes) treating patients with low-flow VMs using a hybrid, closed-bore 1.5T MRI/X-Ray Miyabi suite.
