Fatty liver. Coloured computed tomography (CT) scan of an axial section through the abdomen of a 66 year old woman suffering from fatty liver. At lower centre is a bone of the vertebra (white). The liver is the large organ occupying much of the abdomen at upper left to right (purple). Fatty deposits in the liver show up as blue patches. The liver cells become swollen by large fat droplets.
