Until recently, coronary artery calcification (CAC) scoring has not been a standard component of chest CT reporting. Using data from the National Lung Cancer Screening Trial cohort, Chiles et al  showed that there is strong correlation between visual assessment of CAC on nongated chest CT scans and Agatston scores on electrocardiographic-gated CT scans. CAC on CT (whether nongated or electrocardiographic-gated) is a useful risk stratification tool, as it has been associated with patient mortality 1 ; 2. Heart disease is the leading cause of death in the United States, above cancer. Nearly half of these deaths are the result of coronary artery disease . According to the American College of Cardiology, reporting of the presence of coronary artery calcium on nongated chest CTs provides an opportunity for risk assessment and management for referring providers .
