Researchers at UC Davis have developed a new method that can reduce the radiation dose delivered
to a child during computed tomography (CT) imaging by as much as 80 percent. The new technique, reported
in the journal Radiology, allows radiologists to tailor the dose based upon a child's size.
"If the radiology community used the techniques recommended in this article, there would be a substantial
reduction in pediatric CT dose nationwide," said lead author John M. Boone, professor of radiology and
bioengineering at the UC Davis School of Medicine and Medical Center.
"The purpose of our research was to provide the technologists who run CT scanners with a precise recipe
for lowering the radiation dose levels for pediatric patients by matching radiation to body size, while
still delivering a high-quality CT scan. There is a well-established need for this type of formula for
dose reduction in pediatric CT."
