title: Computed tomography of long-bone osteosarcoma.
abstract: Six cases of osteosarcoma, including medullary, parosteal, periosteal, and intracortical types, were studied by computed tomography (CT). In selected cases, CT provided additional preoperative information as to osseous size and soft-tissue extent. CT helped determine intramedullary involvement and specific sites of cortical destruction and thereby helped to plan the surgical approach to biopsy and the definitive excision.
