Stroke diagnosis, assessment, and outcome prediction
Abstract: In this talk, I will present some of our results on automatic characterization of stroke severity and long-term outcome prediction using morphometric features. I will also discuss predicting brain hemodynamics using physics-informed neural networks (PINN), where we employ in vivo real-time transcranial Doppler (TCD) ultrasound velocity measurements at several locations in the brain and baseline vessel cross-sectional areas acquired from 3D magnetic resonance imaging (MRI) angiograms to provide high-resolution maps of velocity, area, and pressure in the entire vasculature. We validate our predictions against in vivo velocity measurements obtained via 4D flow MRI scans.
