In single shot diffusion imaging of moving organs, undesired motion during diffusion encoding introduces rapid phase variations in the obtained images. When partial Fourier encoding is used to reduce SNR loss in short T2 tissues, the motion-induced rapid phase variation compromises the partial Fourier reconstruction, resulting in “worm-like” artifacts in the reconstructed images. This work shows that by applying phase correction before the partial Fourier reconstruction motion-induced artifacts can be mitigated, improving the quality of diffusion-weighted images in liver applications.
