Visual Scoring of CAC

(A) Three-dimensional rendering of the whole heart (orange), left main coronary artery (LMCA) (blue), left anterior descending coronary artery (LAD) (yellow), left circumflex coronary artery (LCx) (red), and right coronary artery (RCA) (pink). Coronary artery calcium (CAC) (green) was scored on the basis of visual assessment of vessel involvement. (B) CAC scoring performed by evaluating high-density calcifications throughout the lengths of individual affected vessels. (C) Mild vessel involvement, with small volume CAC (green) involving less than one-third of the LCx (red) was scored 1. Intermediate involvement between 1 and 3 was scored 2, as seen in the LAD in (A). (D) High vessel involvement with full CAC (green) involvement of the LMCA (blue) was scored 3.
