Radiologic Technologists | What Do They Do?

Radiologic technologists typically do the following:

  • Adjust and maintain imaging equipment
  • Precisely follow orders from physicians on what areas of the body to image
  • Prepare patients for procedures, including taking a medical history and answering questions about the procedure
  • Protect the patient by shielding exposed areas that do not need to be imaged
  • Position the patient and the equipment in the location needed to get the correct image
  • Operate the computerized equipment to take the images
  • Work with radiologists reading the images to determine whether other images need to be taken
  • Keep detailed patient records


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.

In addition to radiologic technologists and technicians, others who conduct diagnostic imaging procedures include cardiovascular technologists and technicians, diagnostic medical sonographers, and nuclear medicine technologists.
