Conclusion

MSCT is now the accepted standard of care and has displaced EBCT in the detection and quantification of coronary artery calcifications. MSCT has an improved image quality, which is characterized by higher detail resolution and lower image noise levels than EBCT. In addition, MSCT offers the chance for retrospective data selection using ECG-gating to avoid motion artifacts. However, limited temporal resolution of current MSCT techniques seems still to be a certain restriction for the accuracy and reproducibility of coronary calcium measurements. Quantification of coronary calcifications should be reported as absolute calcium mass for better comparison of measuring results between the different scanner types and scan protocols. If available, strategies for reducing the radiation dose, such as tube current modulation techniques, are recommended.
