EurekAlert! -- A new low-dose coronary computed tomography angiography (CTA) technique called adaptive statistical iterative reconstruction (ASIR) can reduce the radiation dose associated with coronary CTA by 27 percent, according to a study in the September issue of the American Journal of Roentgenology (www.ajronline.org). Coronary CTA is a common heart imaging test that helps determine if fatty or calcium deposits have narrowed a patient's coronary arteries.
