Blood Flow in the Human Aorta: from In Vivo 4D Phase Contrast MRI to Computational Hemodynamics

Here we present a from-in vivo-4D PC MRI-to-computational hemodynamics approach to study blood flow in the human aorta. Our aim is the integration of 4D in vivo measurements into patient specific hemodynamic models, complementing detailed in vivo analysis of the bulk flow with reliable in silico calculation of quantities such as the wall shear stress, that cannot be measured in vivo with sufficient accuracy.
