CT and MR imaging can play an important role in the diagnosis of lung cancer. Evaluation of a solitary pulmonary nodule is usually carried out using CT. High-resolution CT is useful in the morphologic diagnosis of a solitary pulmonary nodule. The enhancement characteristics of a pulmonary nodule in contrast-enhancement CT can be a method of distinguishing benign and malignant nodules. MR imaging is superior to CT in contrast resolution and multidirectional imaging capability. Contrast-enhancement MR imaging can describe the enhancement characteristics of the pulmonary lesion better than contrast-enhancement CT. The extent of chest wall and mediastinal invasion of lung cancer can be better shown using MR imaging than CT.
CT和MR成像在肺癌诊断中可发挥重要作用。对孤立性肺结节的评估通常采用CT进行。高分辨率CT有助于孤立性肺结节的形态学诊断。对比增强CT中肺结节的强化特征可作为鉴别良恶性结节的一种方法。MR成像在对比分辨率和多方向成像能力方面优于CT。对比增强MR成像比对比增强CT能更好地描述肺部病变的强化特征。与CT相比，MR成像能更好地显示肺癌胸壁和纵隔侵犯的范围。
