Bone scintigraphy was performed as part of an initial diagnostic evaluation of 70 dogs admitted with primary bone tumors during a 2-year period. Tumors involved major long bones of the appendicular skeleton and included 62 osteosarcomas, 6 fibrosarcomas, and 2 chondrosarcomas. All dogs were free of radiographically detectable pulmonary metastases. Bone scintigraphy was not of value in distinguishing among various types of primary tumors. One dog with an ulnar chondrosarcoma had a scintigraphically detectable occult osseous metastasis or synchronous primary tumor, and 1 dog with osteosarcoma had a scintigraphically detectable lymph node metastasis. Pulmonary metastases were not detected scintigraphically. Of the 70 dogs, 44.3% had areas of increased isotope uptake associated with nonneoplastic disease processes.

Fifty patients with bone primary tumors (multiple myeloma, osteogenic sarcoma, Ewing's sarcoma, giant cell tumor, and others) were studied gammagraphically after injecting 555 MBq of 99mTc-MDP. Eighty per cent of the cases were found in long bones, specially femur and tibia. These two bones were the preferent localization of osteosarcomas. Ewing's neoplasms were mostly diaphysial and osteoclastomas epiphysial.
