FIESTA-C/CISS enables the reconstruction of banding-free bSSFP images, but residual ripple remains in the combined images. Also, in the heart, flow near a stop-band may cause a component image to include significant contributions from out-of-slice spins; this hyper-intense signal persists in images combined using conventional methods. Here, we use a B0 map to combine FIESTA-C/CISS cardiac cine images. Knowledge of B0 enables us to only include pass-band signal in the final image and exclude stop- and bright-bands. In phantom and in vivo studies, the proposed method had less ripple and greatly reduced flow artifacts compared to maximum-intensity projection and root-sum-of-squares.
