CAC scoring from CT scans proves to be powerful tool for physicians

Arlington, VA (June 23, 2022) – The Radiological Society of North America (RSNA) reports that Coronary Artery Calcium (CAC) scoring with use of noncontrast electrocardiographically gated Computed Tomography (CT) is a fast, inexpensive and reproducible examination that effectively-predicts risk for development of cardiovascular diseases and guides preventive therapy in asymptomatic individuals.

In a paper published in the June issue of Radiographics, “Coronary Artery Calcium Scoring: Current Status and Future Directions,” Amit Gupta, MD and colleagues give a comprehensive overview of CAC scoring, including benefits like its ability to yield powerful prognostic data while involving a low radiation dose.

SCCT Education Committee member Sumit Gupta, MBBS, PhD, says the review by Gupta and colleagues provides an algorithmic approach for interpretation of CAC scoring scans and is an invaluable reference of cardiac imagers.

In his invited commentary, Coronary Artery Calcium Scoring—Simple Tool, Big Impact, Gupta explains that the importance of CAC in predicting the risk of coronary heart disease (CHD) is undeniable.

“CAC scoring is extremely useful for early detection and prevention of adverse cardiovascular events, as a decision-aiding tool for initiation of preventative therapy, and as a negative risk factor for excluding cardiovascular risk.”

CAC scores also provide an increased rate of initiation or continuation of lipid-lowering therapies, aspirin, and positive lifestyle changes in patients.

According to Gupta, the future of CAC scoring is promising and may include use of techniques that potentially improve the existing CAC scores as well as advanced artificial intelligence for opportunistic detection of calcified coronary atherosclerosis on CT scans acquired for other purposes.
