Diffuse liver disease. (a) ADC map obtained in a 36-year-old woman with grade 0 steatosis and stage 0 fibrosis shows no pathologic findings. Arrow indicates the right hepatic lobe. (b, c) ADC maps obtained in a 56-year-old man with nonalcoholic fatty liver disease, grade 1 steatosis, and stage 0 fibrosis (b) and in a 50- year-old woman with nonalcoholic fatty liver disease, grade 1 steatosis, and stage 1 fibrosis (c) show restricted diffusion in the right hepatic lobe (arrow). Regions of interest placed in the right hepatic lobe may be used to measure ADC. ADC measurements of the left lateral segment are typically degraded by cardiac motion.
