Chest X-ray is performed to visualise organs and structures within the chest cavity such as the lungs, heart, diaphragm, ribs and the main blood vessels.

Routinely, the examination is performed with the patient standing. The patient will be instructed to take in a deep breath and hold it for a few seconds until the X-ray is taken.
