Direct Quantification of Breast Dose During Coronary CT Angiography and Evaluation of Dose Reduction StrategiesAmerican Journal of Roentgenology | Feb 1, 2011

These two new reports reveal on the risks of radiation damage to sensitive tissues among women undergoing CT angiography of the heart. The first, a retrospective cohort study of 100 patients, found that the chief hazard of cardiac CTA was lung cancer, and that the risk of radiation damage for women is 2.6 times that for men. The second report specifically analyzes the potential damage from coronary CTA to breast tissue, and describes ways to minimize it.
