摘要：

In 120 patients, the mean interscan variability of coronary calcium quantification by electron beam tomography was 19.9% (median 7.8%) for the traditional calcium score, and 16.2% (median 5.7%) for Volumetric scoring. Although this difference was not significant, there: was a significant influence of the total amount of calcium, number of acquired images, and image noise on interscan reproducibility.
