CMR is used for diagnosis of COA and post-intervention assessment. Current limitations of 4D flow MRI include insufficient spatio-temporal resolution, inability to image low velocity regions, and distortion of image due to stent. The presented MRI-based computational enhancement method addresses stated limitations. Patient specific flow velocities defined the boundary conditions for numerical simulations. CFD simulations with AMR were run on segmented aorta geometries. Comparison between in-vivo and CFD results show good agreement, and residual complex flows post-repair compared to healthy control. Computational enhancement of 4D flow MRI can be used as a predictive tool in future clinical settings.
