In this talk, I will present preliminary results for our new efforts to generate patient-specific models of cerebral blood vessels for planning surgical treatment of cerebral AVMs. This project is currently funded with a Radiology Pilot grant. Pre-surgical planning for AVM treatment is currently limited by imaging. Current imaging protocols include digital subtraction angiography (DSA), a dynamic, high-resolution, 2D projected image sequence that reveals blood flow through the brain, and computed tomography angiography (CTA) or magnetic resonance angiography (MRA), which provide 3D but static and lower-resolution vessel imaging. Our goal is to combine DSA and MRA with physics-based modeling to generate patient-specific, dynamic, high-resolution 3D models of blood flow into and out of cerebral AVMs. These models will help to reduce the complex spatial reasoning required to plan and execute the surgical removal of cerebral AVMs and help identify and preserve en passage vessels.
