• Fractal theory provides an effective method of quantitatively describing complicated shapes and patterns in nature. We applied fractal theory for analyzing computed tomography (CT) images. Raw data of upper abdominal CT scanning performed on normal, cirrhotic and fatty livers were transferred to a personal computer, the images were reproduced on the computer, and regions of interest (ROIs) were set on the right lobe of the liver. The raw CT numbers within the ROIs were then calculated to obtain fractal dimensions using a scale conversion method. As a result, CT of the liver, which has a relatively uniform texture pattern, showed fractality. Fractal dimensions of the fatty liver were significantly lower than that of the normal liver. Fractal dimension analysis may provide a quantitative measure of parenchymal patterns of the liver on CT.
