Abstract- In this study, we found the Agatston score to be highly reproducible between observers. Agatston score correlated with both volume score and visual scales, with the advantage of containing more information than mere volumetric or qualitative analysis. VBA Agatston scores, which can be automatically segmented in 95% subjects, is good at reflecting total IAC Agatston score.Finding shows the relationship between IAC Agatston score and above quantitative variables was described by a multiple linear regression model (F=1870, P<0.001, R2=0.978), with standardized coefficient values of 0.982 for calciumvolume and 0.033 for density weighted value. In last, IAC Agatston score is highly reproducible and contains more information than mere volumetric or qualitative analysis. IAC Agatston score, especially the relatively more easily measured VBA Agatston score, may bepotentialĀ  target for futurestudies.
