- W2348885839 abstract "Objective To discuss the influential factors of image quality of 64-slice spiral CT coronary angiography(CTCA).Methods The imaging data of 514 patients with coronary artery disease were retrospectively analyzed.Results According to image evaluation method,the results were excellent in 321 patients(62.5%),good in 138(26.8%),and poor and regarded as failures in 55(10.7%).127 patients underwent prospective electrocardiographic(ECG) gating,but failed in 21 patients(16.5%);387 patients underwent retrospective ECG gating,and failed in 34 patients(8.8%).313 patients had heart rate fluctuation ≤5 beats per minute(BPM),among whom,7(2.2%) failed in examination;175 patients had heart rate from 6 BPM to 10 BPM,among whom,23(13.1%) failed in examination;26 patients had heart rate from 10 BPM to 20 BPM,among whom,25 failed in examination;37 patients had poor breathholding,among whom,32(86.5%)failed in examination.3 failed in examination due to incontrollable bucking and hiccup during the scanning process,3 failed due to obesity and 1 failed due to lower scanning parameter.Conclusion A thorough understanding of influential factors of image quality of 64-slice CTCA and full cooperation from the patients may contribute to better image quaity and higher diagnostic accuracy." @default.
