Methods 136 patients with suspected or diagnosed coronary artery disease were studied with 16-slice spiral CT. Choosing left and right coronary artery in the axial enhancement scanning images, previewing 10 images at 0%-100% of the cardiocycle in increments of 10%, We evaluated grade of the image quality and number of the ratable coronary artery in different reconstruction phases. We selected the most clear image of left and right coronary artery, and recorded the phase. Raw data were reconstructed with thin images at the best phase.

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.

The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

Later, under the untypical parasternal four-chamber view which can thoroughly display the ostium of coronary sinus, the catheter was promoted further to the ostium of coronary venous sinus. Then the echocardiography technician adjusted the transducer of TTE in order to thoroughly confirm the position of the catheter tip. After confirming the position of catheter tip in the coronary venous sinus, the operator inserted the catheter into the coronary venous sinus for 3～4 mm farther. It was noted that if resistance was encountered by operator, the operation must be stopped, which was the same as x-ray fluroscopy as image guiding.
