The
application of balanced SSFP (bSSFP) is limited by the banding artifact
resulting from its sensitivity to field inhomogeneity. A common approach
for band reduction involves multiple measurements with different RF phase
cycling, at the cost of lengthened total imaging time. In this work, we present
a novel time-efficient bSSFP banding reduction technique by utilizing
simultaneous multi-slice (SMS) imaging with CAIPIRINHA to acquire multiple
phase-cycled images within the same imaging time of a single-band bSSFP scan.
Effective band reduction is demonstrated in phantom, abdominal and brain
imaging with SMS factor up to four.
