Correct answer: D — Chest X-ray

In a patient with suspected lung cancer, the first imaging test should be a chest X-ray. If suspicious lesions are seen, a CT scan is then performed for further evaluation. Sputum cytology is rarely used now. PET is used for staging, and MRI has limited use in lung cancer diagnosis.
