Usefulness of Multi-slice CT for Quantification of Coronary Artery Calcium / 医疗卫生装备

ABSTRACT

Objective To introduce the techniques and clinical application of coronary arterial calcification measurements by using the multi-slice CT (MSCT). Methods The recent literature on the coronary artery calcium scoring with MSCT were reviewed. The data acquisition, image reconstruction, quantification methods in assessment of calcium and usefulness of calcium scoring in coronary artery disease were investigated. Results MSCT with nearly isotropic volumetric imaging data, subsecond rotation and retrospective electrocardiographic gating could provide better input data for quantification of coronary arterial calcium volume. Conclusion MSCT allows more precise and repeated measurement of coronary arterial calcification with low interexamination variability.
