Modulated refocusing flip angle single-shot fast spin
echo (SSFSE) is of particular interest for pediatric and
breath-held abdominal imaging. When low minimum
refocusing flip angles are utilized with this technique
in the presence of motion, however, as in the liver,
images may suffer from signal loss due to cardiac
motion. In this work, we characterize the empirical
sensitivity of this modulated SSFSE technique to
impulsive cardiac-like motion and validate our findings
in vivo.
