Physics and Morphology Constrained Quantitative Susceptibility Based Segmentation of Cerebral Veins

Purpose Quantitative susceptibility mapping (QSM) provides venous contrast through the paramagnetic susceptibility of deoxyhemoglobin and can be used to estimate oxygen extraction fraction (OEF), a marker of cerebral metabolism. However, cerebral vein segmentation remains challenging due to artifacts, variability acros...
