WFPI and Child Imaging Safety

Click on the logo to reach the Image Gently/Alliance website



For the purposes of child imaging safety, WFPI aims to secure communication and collaboration between pediatric imaging practitioners via organizations advocating for appropriate practices and resource allocation for children.

To this end, WFPI is a partner of the Alliance for Radiation Safety in Pediatric Imaging and an active participant in the Image Gently campaign, helping to build a framework for addressing international child imaging safety needs. This partnership serves to underscore the synergies of the Image Gently Alliance, WFPI and their wider networks, define individual organizational roles, and promote efficient and effective use of resources for improved imaging healthcare for children. 

WFPI therefore seeks to:

  • support and enhance the Image Gently Alliance and the work of other societies and agencies throughout the world in the goal of promoting radiation protection for children worldwide
  • ensure WFPI's international reach extends to the Alliance and secure the Alliance's input into WFPI focus areas such as radiation safety and region-specific recommendations on radiation protection for children.
Communicating radiation risks in paediatric imaging

Worldwide, an estimated 3.6 billion diagnostic medical examinations, such as X-rays, are performed every year. This number continues to grow as more people access medical care. About 350 million of these are performed on children under 15 years of age.

Using radiation in medical imaging can save lives and prevent the need for more invasive procedures, but inappropriate use may lead to unnecessary and unintended radiation doses for patients. Because children are smaller and have a longer lifespan than adults their risk of developing radiation-induced effects is greater.

“If patients and families are not properly informed about the risks and benefits of an imaging procedure, they may make choices that are more harmful rather than beneficial to their health, such as refusing a CT that is needed or demanding a CT that is not justified,” says Dr Maria del Rosario Perez, a scientist with WHO’s Department of Public Health.

To improve safety WHO launched a Global Initiative on Radiation Safety in Health Care Settings in 2008 with the aim to mobilize the health sector towards safe and effective use of radiation in medicine. One key priority is to improve the communication of radiation risk in paediatric imaging to ensure an effective and balanced benefit-risk dialogue between health care providers, families and patients.

A new WHO publication, “Communicating radiation risks in paediatric imaging: Information to support health care discussions about benefit and risk”, aims to help health-care providers communicate known or potential radiation risks associated with paediatric imaging procedures. The document provides several approaches to help medical professionals answer questions, like “How much radiation will my child receive?” and “How much medical radiation is too much?”

ACR - Child-sizing CT dose

From the American College of Radiology (ACR)

Expand your knowledge of pediatric CT with this FREE interactive case module

Developed and offered by the ACR, the Child-sizing CT Dose: Optimizing Patient Care through Quality Improvement case provides a 360° overview of the latest concepts and practices in radiation dose monitoring for child CT scans.  Whether you are a general or pediatric radiologist, radiologic technologist or medical physicist, this case-based learning activity will provide you with an inside look at concepts related to radiation risk and the relationship of image quality to patient dose.  And as an added benefit, participants will earn continuing education credits – free of charge.

Important Note:  While there is no charge to participate in this educational activity, for CE credit tracking and reporting purposes you will be redirected to the ACR website to log in (or create a login) and add the free module to your shopping cart for immediate access.

Image Gently in Dentistry

Along with dental professionals who wish to optimize the radiation dose used in dental imaging exams performed on children, the campaign message is simple: When performing dental exams on children: 

• Select X-rays for individual needs, not as a routine. Use X-rays only when essential for diagnosis and treatment — based on a review of the patient and their dental history. 
• Use the fastest image receptor available. When film X-ray is used, select “E”- or “F”-speed. Set exposure parameters as low as possible for diagnostic digital imaging.
• Use cone-beam CT (CBCT) only when necessary. CBCT should be restricted in children to cases in which it is essential for diagnosis and treatment planning.
• Collimate beam to area of interest. For intraoral X-rays, collimation should be rectangular to match recording area of detector. For extraoral X-rays, including cone-beam CT, restrict beam to the area needed for diagnosis.
• Always use thyroid shield. The thyroid gland in children is particularly sensitive to radiation. Use of a properly positioned shield significantly reduces the dose to the thyroid. 

• Child-size the exposure time. Less exposure time needed for children as oral structures are smaller than in adults. 


The Image Gently Web site ( always contains the latest research and educational materials to help imaging providers determine the appropriate radiation techniques to use in the imaging of children, as well as helpful protocols for you to follow at your facility.
