FDA posts pediatric imaging advisory

By AuntMinnie.com staff writers

June 25, 2008 -- Children may be more sensitive to radiation received from medical imaging scans than adults, according to the U.S. Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH).

And because children have more rapidly dividing cells that can be exposed to low-level radiation, and a longer expected lifetime during which radiation exposure can develop into cancer, it's important to use the lowest radiation dose necessary during an imaging exam, the FDA said.

The agency is collaborating with Image Gently, a national initiative of the Alliance for Radiation Safety in Pediatric Imaging that includes the Society for Pediatric Radiology, the American College of Radiology, the American Society of Radiologic Technologists, and the American Association of Physicists in Medicine.

Image Gently's first area of focus is computed tomography. The FDA is advising radiology professionals to base CT settings on patient weight or diameter and the particular body part of interest to reduce dose while maintaining diagnostic image quality, in addition to reducing the number of multiple scans with contrast.
