CMR measures of aortic stiffness. Left, axial phase contrast images through the ascending and descending thoracic aorta. Middle, time-velocity flow curves through the ascending (AAo) and descending (DAo) thoracic aorta with measurement of transit time (green line) as the difference in time to half-max flow. Right, oblique sagittal view of the aortic arch with centerline measurement of aortic arch distance.
