Radiological Technology

Radiological Technologyis a broad variety of tests and procedures which covers a number of specialties, including:

  • Plain film, CR cassette or digital detector radiological technology  Ex: x-rays
  • Mammography, used to detect breast cancer
  • Angiography used to view the heart, blood vessels of the body
  • Fluoroscopy Ex: real-time images that show movement
  • Computerized tomography (CT scans), which are cross-sectional images of the body

At the request of a physician, the technologist produces images of a body part or system using equipment that emits x-rays. The radiologist – a doctor who specializes in interpreting x-rays – studies the images and dispenses advice that helps the treating physician make a diagnosis and prescribe an appropriate course of treatment to the patient. As part of their professional duty, technologists:

  • Explain the procedure to patients.
  • Answer questions as fully as possible.
  • Contribute to patient education.
  • Comfort patients and provide emotional support.
  • Position patients and equipment correctly.
  • Ensure that patient, all staff and visitors are protected from radiation.
  • Monitor patients during the procedure.
  • Assist the radiologist for angiographs and interventional procedures.
  • Operate the equipment.

Most radiological procedures are only a short exposure to radiation. Protective coverings can be placed on patients to help minimize their exposure. Technologists wear protective clothing, or stand behind protective barriers, to avoid unnecessary exposure to radiation. Technologists are responsible for the quality of the x-ray images and for providing the correct view of specific body structures or systems, whether on film, a computer monitor, or a television. Some procedures require that barium and/or a dye called contrast medium be given to patients to highlight organs and structures that would not otherwise be seen.
