Abstract

Background: Coronary artery calcium (CAC) score is a prevention tool scarcely used, in part due to its high cost which should not be higher than that of chest computed tomography (CT). Conventional chest CT scan has a predictive value similar to that of gated CT to evaluate CAC using visual or semi-quantitative scales.

Methods: In this retrospective and observational study we included patients (n = 35) undergoing low dose radiation non-gated chest CT and gated CT with evaluation of CAC score within the same hospital stay.

Results: We identified good agreement between the methods for both the qualitative and quantitative assessment, with a mean of 3.86 ± 0.7 segments with coronary artery calcifications identified by gated chest CT, and 3.79 ± 0.6 segments using low radiation dose non-gated chest CT (concordance correlation coefficient 0.98 [95% CI 0.95-0.99]); CAC score assessed by Agatston units was underestimated by 9.8%.

Conclusion: In this study, we demonstrated that low radiation dose CT could accurately provide qualitative and quantitative assess
ment of CAC score.
