The balanced SSFP signal amplitude shows strong dependency on off-resonance frequencies (banding artifact). Several methods have been proposed to broaden the stopband for fat/water selection. However, a suppression is not possible for the whole range of off-resonance frequencies. Here we present a method that accomplishes the frequency selection by randomizing TR for each sequence repetition step and acquiring several acquisitions. It offers selectivity only to the on-resonance signal and suppresses off-resonance frequencies. The method is useful for applications which require averaging, such as low gamma nuclei CSI due to low SNR.
