Radiologic evaluation of osteosarcoma.
Twelve patients with osteosarcoma were evaluated by plain radiographs, radionuclide bone scans and computed tomography (CT). Plain films were the primary radiologic tool for the investigation and follow-up of the skeletal lesion and were particularly helpful for the demonstration of periosteal calcification and bone permeation. The main value of the radiophosphate scan was to detect metastatic or multifocal bone disease. CT was able to show new bone formation in the soft-tissue mass not seen on plain films, to determine proximal intramedullary extension and to assess the response of the bone lesion to preamputation chemotherapy. The lungs were followed at regular intervals with plain chest radiographs and CT scans.
