Chest X-ray provides a 2D image, while a chest CT scan is able to produce a 3D view of your organs. An X-ray is built to examine dense tissues, while a CT scan is better able to capture bones, soft tissues and blood vessels all at the same time.
Can you see a lung tumor on an X-ray?
If lung cancer is involved, chest X-rays can sometimes detect larger tumors, but more often than not fail to diagnose the disease. Chest X-rays also fall short as a tool for lung cancer screening.

Can a CT scan tell if a lung nodule is cancerous?
Yes, lung nodules can be cancerous, though most lung nodules are noncancerous (benign). Lung nodules — small masses of tissue in the lung — are quite common. They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan.
How are CT scans used in detecting COPD?
In people with COPD, chest CT scans are used to detect emphysema (damage to the walls of bronchial air sacs, leading to poor gas exchange), chronic bronchitis (inflammation of the airway lining), or to determine whether another condition, such as heart failure, is causing COPD symptoms.
