Time Efficient Fat Suppression for T1-W SE Imaging at 3T: In Your Face

Axel Hartwig¹, Mathias Engstrm¹, Stefan Skare¹

In post contrast T1w SE imaging, spectrally selective RF pre-pulses are normally used to achieve fat suppression, which increases SAR and reduces the number of slices per TR. This work evaluates two alternative methods for fat saturation that do not involve a pre-pulse. Both methods, using either different transmit bandwidths and/or Slice-Selection Gradient Reversal (SSGR), were found to perform equally well or better w.r.t. fat suppression, acquisition time and T1-w contrast compared to two commercially available spectrally selective pre-pulses.
