4D flow MRI in conjunction with a novel WSS post-processing method that localizes regions of the vessel wall is developed. It exhibits significant differences in inner versus outer-wall vessel regions in curves as well as differences between healthy young and healthy elderly diastolic WSS in the ICA siphon.
