A chest X-ray makes an image of the heart, lungs, airways, main blood vessels and bones of the chest and spine using a small amount of ionising radiation.
It may be used to identify the cause for chest pain or breathlessness. Chest X-rays do not require any preparation. You will be asked to stand against the image plate and will be asked to hold your breath for a few seconds while the image is taken. The whole process takes a few minutes.
