The Slice-Selective Gradient Reversal (SSGR) technique is very effective for robust fat suppression, especially at high field strength (> 1.5T), and can be combined with Spectral Prostration with Inversion Recovery (SPIR) for even better results. As the technique does not introduce any additional scan time or Specific Absorption Rate (SAR), it should be used in spin-echo type sequences at high-filed strength. Particularly for the application of whole body diffusion techniques (DWIBS) at high field, the improved fat suppression may substantially improve image quality.
