What is AutoCAC and AI-CAC®?

​​

AutoCAC (Automated Agatston 1.0)

AutoCAC is a fully automated implementation of the traditional Agatston coronary artery calcium score, effectively representing Agatston 1.0 at scale. It reproduces the conventional CAC methodology based on a fixed radiologic density threshold (≥130 HU) and minimum lesion size criterion (≥ 2.5 mm).

​

AI-CAC® (Automated Agatston 2.0)

AI-CAC® represents the next generation of CAC quantification Agatston 2.0 by moving beyond fixed thresholds to a continuous, AI-CAC engine. It enables detection of small, low-density, or subthreshold plaque that are key to understanding risk.
