Accuracy between two groups was calculated byχ~2 test.Calculate the average effective radiation dose of the 30 patients.Results In group A,seventeen patients underwent both DSCT coronary angiography and SCAG,among 255 segments of 17 patients,105 lesion sites of 70 segments were diagnosed stenosis or obstruction,of them,95 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 90.48%.The agreement of two methods have a high agreement(Kappa =0.853).In group B,13 patients underwent both DSCT coronary angiography and SCAG,among 195 segments of 13 patients,73 lesion sites of 57 segments were diagnosed stenosis or obstruction, of them,65 lesion sites were confirmed by SCAG.The accuracy of DSCTCA was 89.04%.The agreement of two methods have a high agreement(Kappa =0.835). There was no significant difference(χ~2=0.098,p＞0.05) between the accuracy of two groups.The effective radiation dose of 30 patients was 3.67±0.43 mSv.Conclusion Compared with SCAG,prospectively ECG-gated transverse DSCT is a valuable examination to detect and diagnose coronary artery disease with a low dose coronary angiography.The accuracy of the DSCT is approximate to the SCAG.There was no significant difference between the accuracy of two groups.
