Fig 1.
Magnification of LDCT images in the axial view (at two different anatomical levels) showing calcified left main coronary artery (A) and calcified left anterior descending and circumflex coronary arteries (C). In B and D the automated segmentation performed by the software: left main and left anterior descending coronary arteries colored in purple in B and D respectively, and circumflex coronary artery colored in green (D) for a total Agatston score of 460. It should be noted that the aortic valve calcifications are not segmented by the software.
