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.
