Study cautions against use of coronary CT angiography in children

Cardiac-gated CTA radiation doses can vary and be as high as 28.4 mSv (10 times the annual natural background radiation) in children, according to a recent study conducted by researchers from Duke University Medical Center in Durham, NC and Stanford University Medical Center in Palo Alto, CA.
