Figure 1 shows a picture of a computed tomography (CT) scan of two
normal kidneys, looking from the top of the head down. A special dye (contrast
material) was used for this scan. Figure 2 shows a picture from a different CT
scan of two kidneys that are abnormal. These kidneys are small and misshapen
from scarring due to disease.
