Healthcare professionals use many types of diagnostic equipment to diagnose patients. Radiologic technologists specialize in x-ray, computed tomography (CT), and magnetic resonance imaging (MRI) equipment. They may be called CT technicians or MRI technicians, depending on the equipment they work with. Radiologic technologists might also specialize in mammography. Mammographers use low-dose x-ray systems to produce images of the breast. Technologists may be certified in multiple specialties. Some radiologic technologists prepare a mixture for the patient to drink that allows soft tissue to be seen on the images that the radiologist reviews.
Radiologic technologists must be licensed or certified in most states; requirements vary by state. To be licensed in most states, radiologic technologists must have graduated from an accredited program and must pass a certification exam from the state or from The American Registry of Radiologic Technologist (ARRT). For specific state requirements, contact your state’s health board. To keep their certification, radiologic technologists must meet continuing education requirements.
