Shaped fat saturation was realized for the first time on
the basis of multi-frequency optimization of
multidimensional spatially selective RF pulses in
parallel transmission. Shaped fat saturation pulses were
optimized based on a target-driven variable-density 2D
spiral trajectory and evaluated in phantom and human
in-vivo experiments and compared to the commonly used
Gaussian FATSAT pulse. The fat saturation performance of
the proposed RF pulses was found to be similar to the
FATSAT pulse, but allowed also for the simultaneous
saturation of other frequency bands. Furthermore, less
interference with the water band was observed.
