Radiologic-surgical correlative studies were performed for new pulmonary parenchymal nodules in 100 lungs of 84 patients with previously treated extrathoracic malignancies. Ten patients with radiographically typical bronchogenic carcinomas were excluded from analysis. Of 237 nodules resected, 173 (73%) were identified with computed tomography (CT) and 64 (27%) were not. Two hundred seven (87%) were of metastatic origin, 21 (9%) were benign, and nine (4%) were bronchogenic carcinomas. Of those nodules seen with CT and not with radiography of the chest, 84% were of metastatic origin. Between patients with carcinoma and those with sarcoma or melanoma, there was little difference in the percentage of nodules found with CT. More resected nodules were metastases in the sarcoma-melanoma group (93%) than in the carcinoma group (77%). New bronchogenic carcinomas and benign lesions were more common in the carcinoma group. Chest radiography disclosed all nodules resected in 44% of cases, whereas CT disclosed 78%. Of 65 nodules detected as solitary nodules with chest radiography, only 35 (54%) proved to be truly solitary, whereas 35 of 44 (80%) detected with CT were truly solitary.
对84例既往接受过胸外恶性肿瘤治疗患者的100个肺内新出现的肺实质结节进行了放射学与外科相关性研究。10例影像学表现典型的支气管源性癌患者被排除在分析之外。在切除的237个结节中，173个（73%）通过计算机断层扫描（CT）得以识别，64个（27%）未被CT识别。207个（87%）为转移瘤，21个（9%）为良性，9个（4%）为支气管源性癌。在CT显示而胸部X线未显示的那些结节中，84%为转移瘤。在癌患者与肉瘤或黑色素瘤患者之间，CT发现结节的百分比差异不大。肉瘤 - 黑色素瘤组切除的转移瘤结节（93%）比癌组（77%）更多。新的支气管源性癌和良性病变在癌组中更常见。胸部X线在44%的病例中显示了所有切除的结节，而CT显示了78%。在胸部X线检查中检测为孤立结节的65个结节中，只有35个（54%）被证实为真正的孤立结节，而在CT检查中检测出的44个结节中有35个（80%）为真正的孤立结节。
