title: Efficacy of whole lung tomography in diagnosing metastases from solid tumors in children.
abstract: Whole lung, frontal tomography is compared with frontal chest radiography in the diagnosis of pulmonary metastasis in children with cancer. Of 79 patients studied, 65 had a total of 195 routine tomograms. In only 2.7% of studies did tomography yield new information, and in only 1% was an additional lesion visualized. In 27 patients, tomography was performed after an abnormality was seen on the chest radiograph. New information was obtained in 15 (32%) of those 47 studies; additional nodules were identified on six occasions (four metastatic, two inflammatory), but only once was treatment altered. In one study, tomography localized a nodule seen only on a lateral chest radiograph, and in eight studies it excluded metastasis following an abnormal frontal chest radiograph.
