Pulse wave
velocity (PWV) is a commonly used surrogate for arterial stiffness. This
abstract describes a new method to estimate arterial PWV by using MRI
phase-contrast data to tune a 1D blood flow model describing the hemodynamics and
propagation of the arterial pulse wave. Results obtained in a single volunteer
indicate that the proposed approach could be used with
low time resolution methods such as 4D Flow MRI to obtain PWV in the aorta with
much lower variability than the foot-to-foot method.
