Conventional b-SSFP in the presence of field inhomogeneities is often confounded by banding artifact. Here, the contribution of relaxation times, excitation B1 field, and off-resonant spins to these artifacts in b-SSFP has been characterized. A new variant of b-SSFP has been introduced to map the underlying spectral distribution of spins within a frequency range given by 1/TR. The b-SSFP banding can be characterized as a result of a circular convolution between the underlying spectrum and a filter function determined by relaxation times and B1.
