Abstract
CT [computed tomography] was performed in 299 patients with possible pulmonary metastases. Metastases were found in 74 and at CT lesions were demonstrated in all. CT was the most sensitive noninvasive examination, demonstrating metastases in 2 patients considered normal at standard chest radiography and bilateral disease in 4 patients thought to have unilateral disease at standard examination. More nodules were resected at thoracotomy than were shown by CT. These extra nodules were small (< 6 mm) and the majority represented nonmetastatic fibrous lesions.
