GRE sequences benefits from increased SNR at high field and do not suffer from banding artifacts and SAR issues as bSSFP sequences, which makes it a good alternative for some applications that typically use bSSFP at 1.5 T or 3T. We have implemented the autocalibrated multiband GRE cardiac cine sequence at 5 T. The autocalibrated multiband acquisition increases the scan efficiency by reducing the scan time and simplifying the multiband imaging workflow. Iterative reconstruction with sparsity constraints was used which can also accommodate in-plane undersampling. We have evaluated this application on volunteers and achieved cardiac cine images with satisfactory quality.
