title: Positive (99mTc) diphosphonate and 67 Ga-citrate scans in ameloblastoma: case report.
abstract: Technetium-99m-diphosphonate scintigrams and 67Ga citrate bone scans were performed in a patient with known ameloblastoma of the right mandible. The tumor concentrated both radionuclides avidly. The lesion was larger on the gallium scans, presumably due to inflammation of adjacent soft tissue and to poorer instrument resolution for 67Ga than for technitium. If a single radionuclide is to be selected for evaluating the extent of tumor in ameloblastoma, the bone-imaging agent is preferable.
