NEW YORK (Reuters Health) - Educating parents about the radiation exposure associated with computed tomography (CT) does not lead them to cancel CT studies recommended by their doctor, according to findings of a survey of 100 parents given an educational pamphlet of the procedure.
Dr. David B. Larson from University of Colorado Health Sciences Center in Denver associates investigated whether a brief informational handout regarding CT-associated radiation dose and risk improves parental understanding or reverses their consent for their children to undergo CT examinations.
Reading the handout significantly increased the fraction of parents who realized CT uses radiation (from 66 percent to 99 percent) as well as the percentage that believed CT increases the lifetime risk of cancer (13 percent versus 86 percent), the authors report.
Most respondents (59 percent) reported that the information presented was new to them or clarified their understanding.
