Uptake of I-131 in the biliary tract: A potential cause of a false-positive result of scintiscan CLINICAL NUCLEAR MEDICINE Carlisle, M., Cortes, A., McDougall, I. R. 1998; 23 (8): 524-527


Focal uptake of I-131 in the region of the liver was seen on whole-body scans in a 22-year-old asymptomatic woman who had invasive papillary cancer. Hepatic metastases were unlikely because of the clinical risk factors, and a CT scan of the liver was normal. By superimposing the I-131 scintiscan and a hepatobiliary scan, the site of the uptake was shown to be in the biliary tract, and it had migrated to the gallbladder on more delayed images. No pathologic cause was found.
