title: Retrospective comparison of radionuclide scans and computed tomography of the liver and pancreas.
abstract: Computed tomography (CT) and radionuclide examinations of the liver and pancreas in 50 patients were compared retrospectively to evaluate their value as diagnostic tests. CT was superior to 75Se-selenomethionine in evaluating pancreatic disease. Both 99mTc-sulfur colloid scans and CT scans were sensitive detectors of liver masses; however, there were more false positive 99mTc-sulfur colloid scans (16% compared to 4%). CT was superior in detecting biliary obstruction and ascites, in assessing diseases that involved the liver extrinsically, and in evaluating the status of adjacent organs. 99mTc-sulfur colloid scans were more sensitive in detection of diffuse non-neoplastic liver diseases (cirrhosis, hepatitis, and cholangitis). Simultaneous interpretation of CT and radionuclide scans was often more helpful than independent interpretation, and the two techniques are therefore complementary.
