Pulse wave velocity (PWV) is a promising biomarker for decreasing artery diameter and wall stiffness. Recent work showed the possibility to calculate the local PWV from the velocity profil time delay along the artery out of 4D Flow measurements. In this study we used 4 different models (half maximum, maximum, foot-to-foot, cross-correlation) to compare and calculate the PWV in the relatively small femoral arteries in five subjects with stenotic arteries. We found an increased PWV of up to 20 m/s compared to literature values of healthy volunteers. Cross-correlation and half maximum methods yielded consistent results.
