Does cardiac 64-MDCT improve interscan variability for CAC scoring compared to EBT scanners?
Cardiac 64-MDCT provides comparable reproducibility to EBT for coronary artery calcium scoring.
For CAC scoring, interscan variability with newer-generation MDCT scanners was similar to but not superior to that with the EBT scanner.
Budoff et al. (2009) studied this question.
