Cardiac computed tomography (CT) examinations are performed in nearly 30% (1) of the CT sites in the United States. As of 2016, nearly 3 million cardiac CT examinations, such as calcium scoring and coronary computed tomography angiography (CTA), were performed in United States alone. Even though this is a small portion of the 82 million CT procedures performed in the United States, the growing evidence of cardiac CT’s role in triaging patients with cardiovascular diseases (CVDs) indicates that there will be a steep rise in cardiac CT examinations in the near future. One of the main concerns with medical x-ray imaging studies including cardiac CT is the associated radiation dose.
