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.
