Synopsis

Keywords: Pancreas, Diffusion/other diffusion imaging techniques, Diffusion Weighted Imaging, Denoising, M1-nulled, ADCMulti-shot DWI (msDWI) may be improved by M1 motion-compensation, but at a penalty of longer TE and lower SNR. DL-based denoising has recently emerged as an option for DWI, which could help offset this TE penalty. Here we assess the impact of a commercially available DL-based denoising tool in the setting of motion-compensated msDWI.
