Indication of Use
ClearRead CT CAC is image processing software designed to aid physicians in assessing coronary artery calcification on non-gated, non-contrast, standard, or low-dose chest CT scans of adult patients 30 years of age or older. The primary output of ClearRead CT CAC is the Agatston score. ClearRead CT CAC locates calcified coronary lesions and assigns them to one of several coronary arteries: the right coronary artery (RCA), the left main artery (LM), the left anterior descending artery (LAD), and the left circumflex artery (LCX). The software calculates the Agatston score as the sum for each artery while also providing the total across all coronary arteries. The total Agatston score is calibrated to 3.0mm slice thickness and is used to derive a CAC category and the arterial age. The provided segmentations are for illustrative purposes only and are not intended for diagnostic use. ClearRead CT CAC provides adjunctive information and is not intended to be used without clinical expert review.
