Computed tomography and radionuclide imaging of the liver: a comparative evaluation.

The authors retrospectively analyzed the results of radionuclide imaging (RI) and computed tomography (CT) of the liver in 174 patients. RI correctly identified 90% of patients with focal hepatic lesions while CT identified 85%. CT was capable of differentiating tumor, abscess/hematoma, and cyst while RI was more sensitive in the detection of hepatocellular disease. CT distinguished regenerating nodules from other focal lesions. Radionuclide imaging remains the preferred initial screening examination in patients with suspected focal liver disease, while CT is the examination of choice to distinguish obstructive from nonobstructive jaundice.
