The article discusses the use of a computerized tomography (CT) scanner having a far lower associated radiation dose. It profiles Karl Karlson, a cardiac thoracic surgeon, who had been unwilling to undergo coronary CT angiography (CTA) due to the radiation dose associated with the imaging study. It mentions the enhanced CT technology with issues such as the gold standard for diagnosing heart disease.
