Vascular stiffness is known to vary regionally along the
aorta. This may be of particular interest with respect
to focal diseases such as aneurysms. We implemented a
semi-automated method to estimate regional PWV. The
method was applied to estimate PWV in three equally
sized segments in the descending aorta in 8 young and 8
older normal volunteer. The age-related differences in
regional PWV observed agreed with previous studies and
suggest that the PWV in the proximal and mid segments of
the descending aorta increase more rapidly with age than
the PWV in the distal descending aorta.
