The use of multiple radionuclide imaging to differentiate the focal intrahepatic lesion.

Thirty-five patients with various focal intrahepatic lesions were evaluated with multiple radionuclides. Comparison of the blood pool scans with angiography and histology demonstrated an excellent correlation of these studies. Diagnostic accuracy was improved by separating the blood and pool scans into 3 categories. Each category suggested, at most, one further study to provide specific diagnostic information. Thus, by utilizing 3 radiopharmaceuticals, one can be more specific in preoperative diagnoses.
