The role of computed tomography (CT) scanning in the investigation of patients with intrathoracic malignancy has not yet been clearly defined. Current evidence suggests that it is the most sensitive diagnostic imaging technique for identifying the extent of primary lung cancers and their relationship to intrathoracic anatomy. It is an advance in the staging of intrathoracic malignancy as it identifies adenopathy in the paratracheal region and the mediastinum more readily. Discovery of small (less than 0.8 mm) pulmonary nodules is common in patients with some extrathoracic malignant conditions, but differentiating malignant deposits from benign nodules remains a problem. CT has a potential place in radiotherapy field planning and in identifying lung cancers in the occasional patient presenting with suspicious symptoms or positive cytology and a normal chest radiograph.
计算机断层扫描（CT）在胸内恶性肿瘤患者检查中的作用尚未明确界定。目前的证据表明，它是用于确定原发性肺癌范围及其与胸内解剖结构关系的最敏感的诊断成像技术。它是胸内恶性肿瘤分期的一项进展，因为它能更轻易地识别气管旁区域和纵隔的淋巴结肿大。在一些胸外恶性疾病患者中，发现小的（小于0.8毫米）肺结节很常见，但区分恶性沉积物与良性结节仍然是一个问题。CT在放射治疗野规划以及在偶尔出现可疑症状或细胞学检查阳性而胸部X线片正常的患者中识别肺癌方面具有潜在作用。
