Diagnosis of hepatoma by scintigraphy using multiple radionuclides.

The conventional liver scan, using 99mTC-sulfur colloid, is very sensitive in detecting focal abnormalities, but it is nonspecific, since most lesions appear as "cold" defects. Liver scan can be much more specific if the right combination of the many available radiopharmaceuticals is used. This fact is exemmlified by our case report of hepatoma. All scans can be done noninvasively, with low radiation exposure to the patients.
