The purpose is to validate our cardiovascular image analysis toolbox "WaVelocity" for measuring pulse wave velocity (PWV) from cardiac magnetic resonance images against PWV measurements of in-place pressure catheter. The validation was performed using two phantoms: a straight latex tube and an aortic phantom with two different water flow rates. Phase-Contrast para-sagittal image sequences in multiple planes were processed with our image analysis software. Ground truth PWV values were calculated from pressure curves measured by pullback of the catheter. The results show sufficiently high correspondence between calculated MR and catheter PWV to plan for clinical use.
