Overview

Computed tomography is the method of choice for the diagnosis of non-small cell lung cancer. On CT, characteristic findings of non-small cell lung cancer include ground-glass opacity, rounded or spiculated mass, local nodal involvement, intraluminal obstruction, and lobar collapse.

CT scan

After chest X-ray, computed tomography is the best next step in diagnosing non-small cell lung cancer.[1][2][3]

On CT, characteristic findings of non-small cell lung cancer include:[3]

  • Squamous cell carcinoma of the lung
