Radiologic technologists, also called radiographers, perform imaging tests such as X-rays, computed tomography (CT) scans, or magnetic resonance imaging (MRI). They work under the direction of a radiologist, who interprets the images to diagnose illness.

Training programs in radiography are 1 to 4 years long and lead to a certificate, associate degree, or bachelor's degree. State requirements for licensing vary, and radiologic technologists may be registered through the American Registry of Radiologic Technologists.
