Extremity X-Ray
Definition
X-rays of the extremities, such as the hand, wrist, foot, of ankle, are images of internal structures. X-rays are a form of electromagnetic radiation like light, but of higher energy, so they can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray. (See also bone X-ray.)
