title: Hepatic and perihepatic radiolucencies.
abstract: Radiolucencies in and around the liver may be caused by normal or abnormal accumulations of fat or gas. Computed tomography, which measures the differential photon absorption of tissue more accurately than does abdominal radiography, readily demonstrates interfaces between the liver and air or fat. The correlation of these two modalities in detecting and identifying hepatic radiolucencies is explored.
