What is an X-ray?

An X-ray is a form of electromagnetic radiation, just like visible light. In a healthcare setting, a machine sends individual X-ray particles, called photons, through the body and a computer records the images created.

Dense structures, such as bone or metal, will absorb most of the X-ray particles and appear white, while structures containing air will be black and muscle, fat and fluid will appear as shades of gray.

Your X-rays will be reviewed by a board-certified radiologist, who will then pass the results on to your doctor.

How to Prepare for an X-ray

Besides removing all metal objects, there is not much to do to prepare for an X-ray. If you have an intrauterine device (IUD), are pregnant or think you possibly could be pregnant, be sure to tell your healthcare provider.

If abdominal studies are planned and you have had a barium contrast study, such as a barium enema, upper GI series or barium swallow, or have taken medications such as Pepto-Bismol in the last four days; the test may be delayed until the contrast has fully passed out of your system.
