A 62-year-old woman with colorectal cancer and liver metastases who was enrolled into the non-respond group. Images in group a are the diffusion-weighted images corresponding to b = 0 and 1000 s/mm2 as well as the maps of the non-mono-exponential diffusion-related parameters, namely, ADCk, K, DDC, α, Ds and σ before chemotherapy. Images in group b are the diffusion-weighted images corresponding to b = 0 and 1000 s/mm2 as well as the maps of the non-mono-exponential diffusion-related parameters after chemotherapy
