Background: Coronary artery disease (CAD) is the most common type of heart disease and is the leading cause of death globally. It is the disease affecting the coronary arteries which supply the myocardium with oxygen and nutrients. In about 50% of patients with Coronary artery disease, the first manifestation is either sudden death or acute myocardial infarction. Objectives: To estimate and compare the coronary age (vascular age) by sequential and helical scanning methods using syngovia workstation. Methodology: Study Design: Longitudinal study. Study Settings: Department of Radio-diagnosis and imaging, Billroth Hospitals, Chennai. Study Duration: The study was conducted from May 2014 to November 2014. Study Population: Sixty five patients underwent 64-slice dual source CT coronary artery calcium scoring followed by CT coronary angiography. Results: Wilcoxon Signed Ranks Test was applied to compare sequential and helical calcium score measures. The result showed that there is no significant difference between these methods (P = 0.820) except left circumflex and right coronary artery.
