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.
