Different types of X-rays require different preparations. Ask your doctor or nurse to provide you with specific instructions.

What to wear

In general, you undress whatever part of your body needs examination. You may wear a gown to cover yourself during the exam, depending on which area is being X-rayed. You may also be asked to remove jewelry, eyeglasses and any metal objects that may obscure the X-ray image, because these objects can show up on an X-ray.

Contrast material

Before some types of X-rays you're given a liquid called contrast medium. Contrast mediums, such as barium and iodine, help outline a specific area of your body on the X-ray image. You may swallow the contrast medium, or receive it as an injection or an enema.
