Diagnostic X-ray, or radiography, is a special method for taking pictures of areas inside the body. A machine focuses a small amount of radiation on the area of the body to be examined. The X-rays pass through the body, creating an image on film or a computer display.

The equipment, staff, and steps involved are different for each type of diagnostic X-ray procedure. However, they are all invaluable tools in detecting abnormalities and making early diagnosis of disease or injury.
