Standard radiographs and CT were compared in 19 patients operated for suspected pulmonary metastases of osteosarcoma. The sensitivity of CT examination is 87% and the specificity is 31%. Benign nodules and inactive metastases were shown to be misinterpreted as active metastases. It is then proposed, in cases with an initial normal CT, that subsequent examination should be with plain films only. Less than 10% will be operated later with larger lesions, but in one third of this group useless surgery will be avoided.
