Lung cancer is the leading cause of cancer mortality in the United States. Imaging is helpful in the diagnosis of peripheral lung cancers and in the staging of lung neoplasms. CT may establish the benign nature of a solitary pulmonary nodule by detecting either benign types of calcification or fat. Contrast enhancement is a new and innovative method that can be used to distinguish benign from malignant peripheral lung lesions. Both CT and MR play important roles in the preoperative staging of lung carcinoma. Both have significant limitations, however, and surgical staging is often required.
肺癌是美国癌症死亡的主要原因。影像学有助于周围型肺癌的诊断及肺部肿瘤的分期。CT可通过检测良性钙化类型或脂肪来确定孤立性肺结节的良性性质。对比增强是一种可用于区分周围型肺良性与恶性病变的新的创新方法。CT和MR在肺癌术前分期中均发挥重要作用。然而，两者都有显著局限性，通常仍需要手术分期。
