X-rays are a form of radiant energy, like light or radio waves. X-rays can penetrate the body, allowing a radiologist to produce pictures of internal structures and view them on photographic film or on a computer monitor.
When used with care, X-rays are safe. The amount of radiation used during most exams is very minimal. Radiologists and X-ray technologists are trained to use the least amount of radiation necessary to obtain the needed results.

Preparing for an X-Ray Exam

You may be asked to change into a gown provided for you if you are wearing any metal on or around the area to be examined. Remove all jewelry. Let your technologist know if you are or might be pregnant.
