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

Training programs in radiography 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.
