title: Pulmonary evaluation of patients with osteosarcoma: roles of standard radiography, tomography, CT, scintigraphy, and tomoscintigraphy.
abstract: Sixty-one radiologic evaluations were performed on 32 patients with possible pulmonary metastases from osteosarcoma. CT scanning was performed 61 times; standard chest radiography, 58; tomography, 36; scintigraphy, 40; and tomoscintigraphy, 33. Using CT as a reference (positive or negative results only), the sensitivities of the other examinations were 57% (32% of total metastases) for standard radiography, 88% (48%) for tomography, 21% (5%) for scintigraphy, and 41% (8%) for tomoscintigraphy. Of the 193 metastases, 98 were subpleural and 95 were parenchymatous. Five patients had surgery and the others had follow-up. One false-positive CT scan was thus detected. The authors' current evaluation of patients with metastases from osteosarcoma includes chest radiography and CT; the other three examinations are performed only before surgery.
