CT Angiography and Cancer Risk

"As the number of cardiovascular CT angiography scans continues to grow, researchers are attempting to gauge the potential effects of radiation exposure during the procedure. Although extensive epidemiologic studies are not yet available, new research suggests a measurable risk. A study presented at the American Heart Association meeting by Andrew J. Einstein of the Mount Sinai School of Medicine in New York City found that a single cardiovascular CTA study produced a non-negligible lifetime attributable risk (LAR) of cancer in patients. The risk was greatly influenced by factors such as the patient's age and gender, as well at the scan protocols used."
