Objective:The aim of this study was to assess the diagnostic accuracy of dual-source computed tomography(DSCT) in the evaluation of coronary artery disease(CAD).Methods:Fifty-two patients(44 male,8 female,mean age 70.59) with a high pre-test probability of CAD underwent DSCT coronary angiography and selective coronary angiography(SCA).Two physicians independently assessed the images of all coronary segments.Results:The overall sensitivity,specificity,positive and negative predictive value for evaluating CAD were 92.31%,99.82%,90.57%,and 99.32%,respectively.Conclusion:The result indicates that DSCT coronary angiography provides high diagnostic accuracy for assessment of CAD.And it is a better choice for CAD evaluation.
