Objective To evaluate diagnostic accuracy of calcified coronary artery in different calcification score groups,find out cut-off point in calcification score as predictors for diagnostic accuracy of CTA.Methods 100 patients have been included so far.They underwent both 64 MSCT and coronary angiography.Agatston and volume scores were calculated based on segment;those scores were divided by quartiles into different groups.MSCT datasets were analyzed by software with quantitative coronary artery analysis tool based on segment.In different groups,sensitivity and specificity were calculated, ROC curve were performed to find out cutoff point that could predict diagnostic accuracy.Results MSCT showed sensitivity and specificity of 96.9%and 96.7%when volume score≤79 mm~3(cut-off point),100%and 90.9%when volume scored 80 mm,In coronary segment which Agatston score≤65(cut-off point),the diagnostic accuracy was higher than CA,while in coronary segment which Agaston score 180,the diagnostic accuracy was lower.Conclusion In this study,initial results showed cut-off point of calcification score could predict diagnostic accuracy of calcified arteries.
