Figure Lengend Snippet: Overview of 4D Flow and CFD processing methods. a 4D flow MRI methods (blue background) use the MATLAB base program for preprocessing the DICOM MRA images, materialize Mimics used for the segmentation, and EnSight for streamlines generation and 2D cross-section extraction. b CFD processing methods (gray background) geometry segmentation and smoothing using materialize mimics and 3-Matics, fluent for meshing and running CFD simulations using inlet mean velocity waveform from PCMR data. c CFD and 4D flow MRI were compared at four cross-sections perpendicular to the vessel centerline. d 2D Cross-sections extracted: CCA 10 mm below the bifurcation, ICA 10 mm, ICA 15 mm, and ICA 20 mm above the bifurcation. e Velocity profile of a cross-section. f The WSS vectors at the twelve sectors across the corresponding cross-section

Article Snippet: The 4D flow MRI data was analyzed using a custom-written MATLAB code and EnSight (ANSYS, Inc, PA, 2019) software [ 29 ].
