Balanced SSFP is a widely used fast imaging technique because of its high SNR efficiency and the unique T2/T1 contrast. Its main limitation is the banding artifact resulting from its sensitivity to field inhomogeneity. One common approach for banding reduction is to perform multiple acquisitions with different phase cycling, which inevitably lengthens the total imaging time. In this work, we introduce an efficient approach for rapid banding removal in SSFP by utilizing phase-cycled MB imaging with CAIPIRINHA. Using such technique, multiple phase-cycled images can be obtained within the same imaging time as a conventional single SSFP acquisition.
