Radiation in Medical Imaging

Aug 15, 2012

The use of medical imaging has revolutionized the field of medicine and has significantly advanced the diagnosis, treatment and follow-up care people receive, improving health outcomes.

Imaging equipment has become more widely available and the number of imaging exams performed each year has also increased. Attention to radiation exposure from medical imaging exams has also grown.

There is some concern that radiation from medical x-rays could minimally increase your risk of developing cancer later in life. This potential risk decreases with age, so attention to radiation exposure is most important for children and young adults.

There is no definitive scientific evidence that radiation from medical imaging exams causes cancer. To be safe, the medical community advocates taking reasonable precautions to limit the radiation exposure from medical imaging, including:

    • Image only when there is a clear reason
    • Use the least amount of radiation needed for a quality diagnostic exam
    • Image only the indicated area
    • Limit multiple scans
    • Suggest alternative imaging exams that do not use radiation, such as MRI or ultrasound, when appropriate


Suburban Imaging has procedures in place to ensure that each exam is appropriate by following the American College of Radiology's Appropriateness Criteria. To ensure that we use the lowest radiation dose necessary to obtain good quality images, Suburban Imaging continually evaluates our processes and exam protocols. Read more about Radiation Safety at Suburban Imaging.
