Diffusion MRI of the liver has important applications in the detection of metastatic lesions. Unfortunately, conventional diffusion MRI is highly sensitive to cardiac-induced motion in the left lobe, whereas recently developed motion-robust diffusion MRI methods lead to lower SNR. This work demonstrates the feasibility of combining motion-robust diffusion MRI with DL reconstruction for improved DWI of the liver, including high motion robustness and high SNR. In early-stage evaluation, the combined technique provides excellent motion robustness, quantitative reliability, and high SNR throughout the entire liver, and may have application in the detection and evaluation of metastatic liver lesions.
