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.
