In vivo three-dimensional MR wall shear stress estimation in ascending aortic dilatation.
To estimate surface-based wall shear stress (WSS) and evaluate flow patterns in ascending aortic dilatation (AscAD) using a high-resolution, time-resolved, three-dimensional (3D), three-directional velocity encoded, radially undersampled phase contrast MR sequence (4D PC-MRI). ⋯ Changes in WSS in the ascending aorta of AscAD correspond to observed alterations in flow patterns compared to controls.
