Workflow for the analysis of PC MRI data, including 1) preprocessing of all 4D flow, 2D-1dir and 2D-3dir images, 2) aortic 3D segmentation from 4D flow data along with positioning of a plane co-registered with the 2D slice coordinates, and 3) 2D segmentation of ascending and descending aortic borders used for the estimation of new volume (Q net ), peak flow (Q max ) as well as peak velocity magnitude (Vmag max ) and through-plane velocity (Vz max ).
