title: Computer tomography, radionuclide imaging and ultrasonography in hepatic mass lesions.
abstract: The livers of 86 patients comprising this report were examined by both transmission computerized tomography (CT) and radionuclide scans (LS). Fifty-nine of them were also examined by gray-scale ultrasound (US). In a comparative study, the strengths and weaknesses of each modality were evaluated. CT demonstrated 85%. US 82%, and LS 73% of masses involving the liver. Because of better resolution and sectioning capabilities, together with stop-motion imaging, CT and US detected smaller and deeper mass lesions than did LS. However, LS was more informative in hepatocellular disorders than was US or CT. Our experience indicated that information obtained on the liver and surrounding structures by each imaging modality used here tends to be somewhat unique, and thus these procedures complement one another rather than being competitive.
