Why might I have a chest x-ray?
If you have symptoms such as feeling short of breath, a chest x-ray can help doctors find out if it’s caused by a heart or lung condition or something else.
You would also have a chest x-ray done as part of routine work up for heart surgery.
If your doctor thinks you may have a heart condition, they will arrange for you to have other tests too.
What happens during a chest x-ray?
You will be asked to remove your clothes down to your waist, put on a hospital gown and also remove jewellery.
You will stand against a photographic plate and the radiographer, the health professional who takes the x-rays, will ask you to take a deep breath and hold it (this helps to improve the quality of the x-ray image). Once they have taken the x-ray they will advise you to breathe normally again.
You may have chest x-rays taken from different angles, but they only take a few seconds each time and the whole process usually takes a few minutes. The radiographer will check the images before you leave and advise you when the results will be available to your doctor.
Having a chest x-ray is painless, although the photographic plate is a bit cold and hard.
If you are pregnant or think you might be, make sure you tell your doctor.
