| Objective To investigate the influencing factors on the image quality of 64-slice CT coronary angiography, and to discuss the value of ECG edition software of 64-slice CT in coronary artery imaging. Methods The coronary artery imaging data of 981 patients who examined by 64-slice CT were collected from August 2005 to April 2006. The image quality and its influencing factors were analyzed. Results The patient's heart rate, fluctuation of heart rate and breathing movement were negatively related to the image quality. Conclusion Image quality of 64-slice CT coronary angiography affected by the patient's heart rate, fluctuation of heart rate, breathing artifact and reconstruction phase. |
