3T MRI is advantageous to CMR, but its main field
inhomogeneity often introduces banding artifacts in SSFP
cine. In this study, we propose an SSFP cine protocol
with a shorter TR by using a slightly lower spatial
resolution and a fast RF pulse. 10 healthy volunteers
and 6 cardiac patients were scanned using the new
protocol and compared with the standard SSFP protocol at
3T. Results show that the shorter TR improves robustness
of SSFP cine to field inhomogeneity and shortens scan
time without affecting LV function measurements. The
proposed approach is a robust, fast and accurate way for
SSFP cine at 3T.
