The application of cine fast-spin echo (FSE) in
measuring abdominal aortic wall displacements is
hampered by respiratory motions and flow turbulences.
Free-breathing black-blood (FBBB) cine FSE is proposed
to locally select the abdominal aorta without the
respiratory artifacts from adjacent tissues. Flow
artifacts are inhibited using the delay alternating with
nutation for tailored excitation flow suppression pulse
(DANTE). The transverse images and M-mode confirmed that
respiratory triggering or navigation is not needed for
the FBBB cine FSE. Clinical indexes can be derived from
aortic wall displacements using the FBBB cine FSE.
