Cardiovascular magnetic resonance (CMR) aortic pulse wave velocity (PWV) assessment: a Through-plane flow measurements at the level of the pulmonary trunk cutting across both the ascending and the proximal descending aorta, just below the diaphragm perpendicular to the descending aorta and just above the bifurcation of the abdominal aorta. b Corresponding velocity-encoded images. c PWV is subsequently calculated from the distance along the aortic centerline between measurement locations (Δx) and the foot-to-foot transit time from the resulting velocity waveforms (Δt)
