Measuring PWV with MRI would provide a useful tool to measure arterial stiffness locally. However, the limitation of MRI for this implementation is temporal resolution. This study validates a technique to measure local PWV at up to only 5 cm of the carotid arteries using 2D PC CINE MRI data of a high temporal resolution compressed sensing (CS) reconstruction. The method is validated using a pulsatile flow phantom and two groups of 10 elderly and 10 younger healthy volunteers. A significant difference between age groups was found.
