title: Should intravenous contrast be used for chest CT in children with nonlymphomatous extrathoracic malignancies?
abstract: Intravenous contrast for thoracic CT examinations did not help in the staging of 75 consecutive pediatric patients with extrathoracic malignancies. Thirteen developed pulmonary metastases. In three of four children with hilar or mediastinal metastatic adenopathy, the abnormal lymph nodes were seen on the plain chest radiographs as well as the CT.
