The reverse gradient technique showed equal fat suppression efficiency and higher SNR and CNR when compared to the RF inversion method in liver DWI, while the measured ADC values were consistent among the two. Chemical shift artifacts remain problematic in abdominal diffusion imaging due to the challenges in B0 field shimming, and the adoption of the optimal fat suppression technique for different application scenarios is important to balance between fat suppression, SNR, and ADC accuracy.
