    Radiologic Technologist

    A radiologic technologist, also may be known as medical radiation technologist and as radiographer, performs imaging of the human body for diagnosing or treating medical problems. Radiologic technologists work in hospitals, clinics, medical laboratories, government agencies, industry and private practices. Radiologic technologists use their expertise and knowledge of patient handling , physics ,anatomy, physiology, pathology and radiology to assess patients, develop optimal radiologic techniques or plans and evaluate resulting radiographic images.

    What is the ARRT?

    The ARRT is a national organization that seeks to set high standards for Radiologic Technologists by creating examination procedures, ethical standards, and continuing education requirements. Many states take ARRT exam scores into consideration when determining whether or not to license an individual. Being certified and registered with the ARRT is also an indicator to prospective employers that you have met nationally recognized standards and that you are fit to be employed in a radiology position.

    Certification Types Offered through ARRT

    The ARRT offers the following primary and continuing education certifications:

    Primary ARRT Certification Categories

    • Radiography
    • Nuclear Medicine
    • Radiation Therapy
    • Sonography
    • MRI - Magnetic Resonance Imaging

    Continuing Education ARRT Certifications

    • Mammography
    • Computed Tomography
    • MRI
    • Quality Management
    • Bone Densitometry
    • Cardiac Interventional Radiography
    • Vascular Interventional Radiography
    • Vascular Sonography
    • Breast Sonography
    • R.A. (Radiologist Assistant)

    Prerequisites for the ARRT Exam

    Before you can take the ARRT exam, you must have received formal training from an accredited radiology school. Use our radiology school directory to find an accredited radiology school or search for radiology schools in your state.

    About the ARRT Exam

    The general radiographer exam consists of five sections on positioning terminology and technique, radiographic procedures, image production and evaluation, equipment operation and quality control, radiation protection, as well as patient care and education. The following chart gives you a snapshot of how the test is broken down:

    Radiographer Test Categories% of Test# of Questions
    Radiation Protection 20% 40
    Equipment Operation & Quality Control 12% 24

    Radiography professionals fill a vital role in the detection and diagnosis of diseases, cancers and other patient injuries, and can help treat illnesses as well. Radiographers can also assist surgeons and other physicians to minimize the risks of surgery by providing detailed, internal images of the patient's body during the surgery.

    Radiography opportunities are available for people with a wide variety of skill sets and education levels. Radiography careers often include working with one the following:

    1. X-ray machines
    2. Large diagnostic machines
    3. Intravenous radioactive medicine
    4. Radiation in the form of therapy

    The field of radiography spans a variety of different occupations, including the following:

    • X-ray technicians/Radiologic technologists: The term "X-ray technician" is outdated but still persists, although these professionals are now called radiologic technologists or radiographers. These technologists use X-ray machines for purposes such as locating broken bones, isolating tumors in the lungs, observing the GI tract or identifying possible problems with a patient's vascular system. In the 1970s, magnetic resonance imaging (MRI) and computed tomography (CT) scanners were created as a replacement for the common radiograph to give detailed three-dimensional views of a patient's body. The MRI machine uses magnetic fields and radio waves to create the images, while CT scanners produce hundreds of thin X-ray "slices" as the patient moves through the machine.
    • Nuclear medicine technologists: Sometimes, a diagnostic scan does not reveal the issue, or the cause of the issue. In some cases, a radioactive substance needs to be administered during a scan. In these instances, nuclear medicine technologists prepare radioactive mixtures for the patient to assist with the diagnostic imaging.
    • Radiation therapists: These professionals use radiation to treat cancer or other diseases. The radiation-emitting machines can be based on X-rays or a radioactive isotope of cobalt. Medical linear accelerators use high-energy X-rays, according to the Bureau of Labor Statistics (, 2012). Radiation therapists are also a member of an oncology team, which help treat cancer in patients.

    While some radiographic technologist positions are available for individuals without a degree, many positions may require an associate or a bachelor's degree in addition to the completion of a certification program. Some states require operating radiographers to be licensed, the BLS reports. Check with your state to determine your licensure requirements, as regulations vary by state.
