Radiologic and MRI technologists

What Radiologic and MRI Technologists Do

Radiologic technologists perform diagnostic imaging examinations, such as x rays, on patients. MRI technologists operate magnetic resonance imaging (MRI) scanners to create diagnostic images.


Radiologic and MRI 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 order to get the correct image
  • Operate the computerized equipment to take the images
  • Work with physicians to evaluate the images and to determine whether additional images need to be taken
  • Keep detailed patient records

Healthcare professionals use many types of equipment to diagnose patients. Radiologic technologists specialize in x-ray, and computed tomography (CT) imaging. Some radiologic technologists prepare a mixture for the patient to drink that allows soft tissue to be viewed on the images that the radiologist reviews. 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.

MRI technologists specialize in magnetic resonance imaging scanners. MRI technologists inject patients with contrast dyes so that the images will show up on the scanner. The scanners use magnetic fields in combination with the contrast agent to produce images that a physician can use to diagnose medical problems.

Healthcare professionals who specialize in other diagnostic equipment include nuclear medicine technologists, diagnostic medical sonographers, and cardiovascular technologists and technicians, including vascular technologists.

How to Become a Radiologic or MRI Technologist

An associate’s degree is the most common educational path for radiologic and MRI technologists. Technologists must be licensed or certified in some states; requirements vary by state.                       


There are postsecondary education programs in radiography and MRI that lead to graduate certificates, associate’s degrees, or bachelor’s degrees. Associate’s degree programs are the most common. Education programs typically include both classroom training and clinical training. Coursework includes anatomy, pathology, patient care, radiation physics and protection, and image evaluation.

The Joint Review Committee on Education in Radiologic Technology (JRCERT) accredits programs in radiography. Completing an accredited program is required for licensure in some states.

High school students who are interested in radiologic or MRI technology should take courses that focus on science and math. Suggested courses include anatomy, biology, chemistry, physiology, mathematics, and physics.          

Work Experience in a Related Occupation

Many MRI technologists start out as radiologic technologists. After gaining experience in all of the areas of radiologic technology, they then begin to specialize in giving MRI examinations. After a few years, most technicians are considered to be experienced enough to sit for an MRI certification exam.

Other MRI technologists may be required to complete specific imaging examinations on patients and then have this information verified by a doctor before being considered an MRI technologist.

Licenses, Certifications, and Registrations

Radiologic and MRI technologists must be licensed or certified in some states; requirements vary by state. To become licensed, technologists must graduate from an accredited program and must pass a certification exam from the state or from the American Registry of Radiologic Technologists (ARRT).

Many MRI technologists are first licensed or certified radiologic technologists who have the required amount of work experience in magnetic resonance imaging to meet certification standards, which includes a set number of documented imaging examinations. Those who are not radiologic technologists need to complete a formal education program before taking the certification exam. MRI certification is available from the ARRT and is accepted by most states for licensure.

For specific state requirements, contact the state’s health board.

Important Qualities

Detail oriented. Radiologic and MRI technologists must follow exact instructions to get the images needed to diagnose and treat the patient.

Interpersonal skills. Radiologic and MRI technologists work closely with patients who may be in extreme pain or mentally stressed. Technologists must be able to put the patient at ease to get usable images.

Math skills. Radiologic and MRI technologists may need to calculate and mix the right dose of chemicals used in imaging procedures.

Physical stamina. Radiologic and MRI technologists often work on their feet for long periods during the day and they must be able to lift and move patients who need assistance.

Technical skills. Radiologic and MRI technologists must understand how to operate complex machinery.

Total, all occupations



Employment of radiologic technologists is projected to grow 21 percent from 2012 to 2022, faster than the average for all occupations. Employment of MRI technologists is projected to grow 24 percent from 2012 to 2022, much faster than the average for all occupations.

As the population grows older, there will be an increase in medical conditions, such as breaks and fractures caused by osteoporosis, which can require imaging to diagnose them. Radiologic and MRI technologists will be needed to maintain and use the diagnostic equipment. In addition, federal health legislation will expand the number of patients who have access to health insurance, increasing patient access to medical care.

Although hospitals will remain the main employer of radiologic and MRI technologists, a number of new jobs will be in physicians' offices and in outpatient imaging centers. Employment in these healthcare settings is expected to increase because of the shift toward outpatient care whenever possible. Outpatient care is encouraged by third-party payers as a cost-saving measure and is made possible by technological advances, such as less expensive equipment, that allow for more procedures to be done outside of hospitals.

Job Prospects

Technologists with multiple certifications will have the best job prospects.
