Although whole-body DWI (wbDWI) is generally performed using the multistation approach, a recent work has demonstrated that the continuously moving table (CMT) approach produces images with more homogeneity in terms of temporal and spatial discontinuities. In the CMT-wbDWI, short tau inversion recovery (STIR) was used to suppress fat but remains of the fat signal could still be observed in the images. In this abstract, we propose to use the gradient reversal (GR) algorithm for CMT-wbDWI and analyze how the GR algorithm can improve the fat suppression results of the CMT sequences.
