Extremity x-ray

An extremity x-ray is an image of the hands, wrist, feet, ankle, leg, thigh, forearm humerus or upper arm, hip, shoulder or all of these areas. The term "extremity" often refers to a human limb.

X-rays are a form of radiation that passes through 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.
