Fig 1.
CAC scoring methodology and example image.
CAC scoring methodology is depicted on the left. The Agatston (CAC) score is what is used in clinical practice. On the right is an example of a single slice (image) from a CAC scan that demonstrates calcification in the left anterior descending and right coronary arteries. CAC, coronary artery calcium; CT, computed tomography.
