What are x-rays?

X-rays are also called “ionizing radiation,” and they're a type of energy ray that can penetrate the human body. X-rays are on the same spectrum (the electromagnetic spectrum) as visible light, ultraviolet light, TV and radio waves, and radar, each of which is determined by its unique range of wavelengths. X-rays have been used for more than a century to help doctors evaluate injuries and conditions inside the body without the need for invasive surgery.

What happens during an x-ray procedure?

X-rays are quick and painless; in fact, the only discomfort you may experience will come from moving an injured area or holding a specific position during the x-ray so the machine can take the clearest pictures possible. The machine itself does not come in contact with you in any way. Prior to the exam, you may need to change into a medical gown; if your leg or arm is being evaluated, you may not need to change as long as you're wearing short sleeves or shorts. You'll also be asked to remove metal jewelry and other objects containing metal. During the exam, you'll lie on an exam table, sit beside the exam table, or stand in front of an x-ray screen, depending on the area of your body that's being x-rayed. The x-ray machine will be positioned over or in front of the area to be imaged and the technician will leave the room. A few moments later, the x-ray will be complete. In most cases, more than one image will be made.

What are x-rays used to evaluate?

X-rays can be used to evaluate many types of injuries, including broken bones and joint injuries. They're often the first type of imaging used to provide baseline information about an injury, and may be followed up by more comprehensive imaging such as MRI.
