Abstract

Time-resolved, 3-dimensional phase-contrast magnetic resonance imaging (3D+t PCMRI) is employed to obtain complete spatial and temporal coverage of the vessels blood combined with spatially registered 3-directional pulsatile blood flow velocities[1][2]. Recent studies have reported that Wall Shear Stress (WSS) quantification from PCMRI are able to use the WSS as biomarkers for different aortas pathologies [3]. Figure [1] shows the pathline visualization of blood flow during one cardiac cycle in the heart of a healthy patient at peak early LV filling, diastasis, peak atrial contraction, and peak systole.
