MRI images must be interpreted by a qualified physician.
Radiologic technicians and technologists are medical imaging techs who may be trained in a variety of imaging procedures, including X-rays, diagnostic sonography, computer assisted tomography, magnetic resonance imaging or MRI and fluoroscopy. Licensing of medical imaging techs is the responsibility of individual states, and educational and experience requirements may vary. Medical imaging techs who are certified in a variety of technologies, including MRI and fluoroscopy, may have the best chances for employment or advancement, according to the U.S. Department of Labor's Bureau of Labor Statistics.
MRI
Magnetic resonance imaging uses the resonant frequency properties of atoms inside a magnetic field to create an image of internal body parts. Medical imaging technologists who are trained to operate MRI equipment are responsible for generating images of areas of the body ranging from soft tissue to bones or internal organs. Trained surgeons and physicians are responsible for interpreting the images. MRI-qualified techs typically work in hospitals or imaging clinics. Most states require MRI technologists to be licensed. Certification in the field is voluntary.
Fluoroscopy
Fluoroscopy is a medical imaging technology that allows the physician to observe a continuous X-ray image on a monitor. Physicians may introduce a contrast media into the patient and track its movement via fluoroscope when performing procedures involving the vascular system. Surgeons may use fluoroscopy to track the movement of instruments during a surgical procedure. Fluoroscopy training is required for radiologic technologists who wish to become certified by the American Registry of Radiologic Technologists. The California Department of Public Health requires radiologic technologists to have a fluoroscopy permit prior to operating fluoroscopy equipment in the state.
Other Imaging Technologies
X-ray is one of the oldest medical imaging technologies still in use. Excess exposure to the radiation generated by X-ray machines can result in health problems, so medical imaging techs must take added precautions when performing X-ray examinations. Ultrasound has gained in popularity as a diagnostic technique because it does not produce any harmful radiation. Ultrasound, also referred to as sonography, is frequently used with pregnant women to observe fetal development. Techs who are trained in computed tomography are able to generate 3D images using cross-sectional X-rays.
Employment Considerations
Educational and training requirements for medical imaging technicians and technologists vary based on the state where they work and the imaging discipline they are trained in. Programs may be found in vocational schools, technical institutes, community colleges or traditional four-year colleges and universities. These programs may result in a certificate, diploma, associate degree or bachelor's degree. Certification in MRI and fluoroscopy is typically voluntary but may lead to greater employment and advancement opportunities. The American Registry of Radiologic Technologists notes that as of July 2015, candidates for radiography, nuclear medicine technology, radiation therapy and MRI certification must hold at least an associate degree.
