Research Article: Calcium Concentration of Individual Coronary Calcified Plaques as Measured by Multidetector Row Computed Tomography

Abstract

---

Background— Characteristics of individual calcified plaques, especially calcium concentration (CC), may provide incremental value to global calcium scores in the assessment of plaque burden and risk of coronary events and evaluation of therapeutic intervention. In this study, therefore, we assessed the characteristics of individual calcified plaques and their relationship to other parameters derived from CT analysis of coronary calcium in a community-based cross-sectional cohort.
