Cancer risks increase with complex heart tests

Summary:
Complex heart imaging can increase cancer risks for children throughout their lifetime, according to a new study that is the first to quantify cumulative radiation doses in pediatric heart patients and predicted lifetime cancer risks based on the types of exposures. Researchers found that radiation from standard X-rays don't significantly raise cancer risks for young children, in general, but children undergoing more complex procedures with higher radiation -- like cardiac catherizations and computed tomography (CT) scans have higher risks.

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.

In the study, Johnson and fellow researchers found that radiation from standard X-rays don't significantly raise cancer risks for young children, in general, but children undergoing more complex procedures with higher radiation -- like cardiac catherizations and computed tomography (CT) scans have higher risks.

"Cancer risk overall is relatively low, but we hope that this awareness will encourage providers to limit radiation exposure in children, when alternative procedures can offer the same benefit with less radiation," Johnson said.

Researchers reviewed medical records to find the most common imaging procedures, calculated how much radiation organs absorb during each procedure, then used a National Academy of Sciences report to analyze lifetime cancer risks based on the amounts of each procedure's exposure. Lifetime cancer risk increases ranged from 0.002 percent for chest X-rays to 0.4 percent for complex CT scans and cardiac catheterizations.

Johnson is an assistant professor at the University of Tennessee Health Science Center and specializes in congenital heart disease and advanced cardiovascular imaging. He helped complete the research at Duke University Medical Center, where he completed his pediatric cardiology and advance imaging fellowships.
