Definition of Extremity x-ray:

An extremity x-ray is an image of the hands, wrist, or feet, or all of these areas. The term "extremity" often specifically refers to a human hand or foot.

X-rays are a form of radiation that 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.

How the test is performed:

The test is performed in a hospital radiology department or in the health care provider's office by an x-ray technologist. You will be asked to place the specific area being x-rayed (such as your hand, wrist, or foot) on the table, and to hold still as the x-ray is taken. You may be asked to change position, so additional x-rays can be taken.

How to prepare for the test:

Tell the health care provider if you are pregnant. Remove all jewelry from the area being imaged.

How the test will feel:

In general, there is no discomfort, although you may be slightly uncomfortable while the extremity is positioned for the x-ray.

Why the test is performed:

Your doctor may order this test if you have signs of a fractures, tumors, or degenerative conditions in a hand, foot, or wrist.
