Pediatric Patients
WARNING
AVERTISSEMENT
 Health care professionals and hospital administrators take special care in
reducing radiation exposure to pediatric patients by following these steps:
 Discuss the rationale for the examination with the patient and/or parent to
ensure a clear understanding of benefits and risks.
 Reduce the number of inappropriate referrals (i.e., justify X-ray imaging exams)
by:
 determining if the examination is needed to answer a clinical question,
 considering alternate exams that use less or no radiation exposure, such as
ultrasound or MRI, if appropriate, and
 checking the patient's medical imaging history to avoid duplicate exams.
 Use the pediatric protocols or technique charts included as following table:
