This work examines the scope and accuracy of CT in the detection of tumors, abscesses, cysts, and parenchymal disorders of the liver. While CT remains an emerging modality, it is shown to be equal to nuclear medicine in detecting mass lesions. It has also been possible to distinguish obstructive from nonobstructive jaundice. Presently, CT is not well suited to the study of cirrhosis. Technological advances in CT design and contrast agents offer promise of significantly improved resolution.
