Custom-designed spatial spectral pulses (SPSP) have been shown to suppress fat signal effectively by taking advantage of chemical shift along the fast direction. However, the proper design of such SPSP pulses depends on many variables and their performance was never evaluated so far. In this work, a simplified implementation of this approach and a detailed performance evaluation is done. Reduced FOV diffusion-weighted images subject are acquired in phantom and human and compared to two other state-of-the-art fat suppression techniques. In conclusion, the proposed approach demonstrated here can offer the best compromise regarding residual fat signal and acquisition speed.
