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.
