One issue with single-shot diffusion-weighted EPI image of the liver is the signal loss in regions proximal to the heart due to cardiac motion. Various techniques in both data acquisition and post-processing have been proposed to mitigate this issue. In this work we present a new post-processing strategy to reduce the signal loss by combining the individual diffusion-weighted images with appropriate weights. In-vivo results demonstrated the feasibility.
