title: Computed tomography of the liver.
abstract: The diagnostic value of computed tomography (CT) of the liver depends on proper conduct of the examination, knowledgeable interpretation of findings, and an appreciation of the capabilities and limitations of the method. This report documents 10 months of experience with abdominal CT in more than 600 liver examinations using a system fast enough to eliminate respiratory motion. This experience supplied data on the CT appearance of the normal liver and its variations and of various hepatic abnormalities, on the conduct of the examination, including the appropriate of contrast material, and on some of the problems that reduce the technical quality of the examination. CT was highly accurate, but not infallible, in detecting and defining space-occupying lesions and in detecting fatty infiltration; it was less helpful in detecting diffuse hepatic disease. In bile duct obstruction, CT displayed not only the dilated ducts but often the obstructing lesion.
