Apfaltrer G, et al. - Experts sought to examine the diagnostic accuracy and radiation dose of high-pitch CT coronary artery calcium scoring (CACS) with tin filtration (Sn100kVp) vs standard 120kVp high-pitch acquisition. Using high-pitch low-voltage tin-filtered acquisitions, CACS indicated excellent agreement in Agatston score and percentile-based cardiac risk categorization with standard 120kVp high-pitch acquisitions. While maintaining accurate risk prediction, radiation dose was also significantly reduced by 78%.
