Diffusion weighted imaging using single-shot turbo spin-echo (DWI-SShTSE) is increasingly used due to its robustness to geometric distortions, but often suffers from incomplete fat suppression at 3T using spectrally-selective fat suppression methods (SPIR/SPAIR etc.) in challenging areas with large field inhomogeneities. STIR can improve the fat suppression but at the expense of reduced SNR. In this work, we developed a multi-echo Dixon DWI-SShTSE sequence with shared field map between lower and higher b-values for uniform fat suppression without using image navigator and increasing scan times. We also demonstrated its robustness to the phase variations due to diffusion gradients.
