Numerous studies have provided evidence of elevated aortic pulse-wave velocity (PWV) to complement the traditional cardiovascular disease risk factors. Quantification of peripheral PWV (e.g. iliac, femoral and popliteal arteries) has received much less attention even though some studies indicate peripheral PWV to be preferable since, unlike central artery PWV, peripheral PWV does not increase with age and its elevation may therefore be more specific to disease. Here we demonstrate a projection-based MRI method for quantification of PWV at multiple arterial segments as a possible means for detection of early endothelial dysfunction.
