Study measures radiation exposure for children with heart disease

Complex heart imaging can increase cancer risks for children throughout their lifetime, according to a new study co-authored by Le Bonheur Cardiologist Jason Johnson, MD, MHS. The study, which appears in the June 9, 2014 issue of the American Heart Association's journal Circulation, is the first in which researchers quantified cumulative radiation doses in pediatric heart patients and predicted lifetime cancer risks based on the types of exposures.
