Abstract：Objective To explore the effects of breathing training on the imaging quality of the dual-source CT coronary angiography (CTCA) .Methods 200 patients with suspected coronary artery disease underwent CT coronary angiography (CTCA) ,and were divided into two groups according to breath hold effect .We evaluated the image quality after the in-spection .Results All patients were successfully completed the examination ,150 cases in group A ,whose breathless effects was good ,the subjective image quality evaluation was respectively grade Ⅰ in 108 cases ,grades Ⅱ in 29 cases and grades Ⅲ in 13 cases ,50 cases in group B ,whose breathless is poor ,the subjective image quality evaluation was respec-tively grade Ⅰ in 5 cases ,grades Ⅱ in 33 cases ,grades Ⅲ in 12 cases ,with statistic significant of differences between the groups ( P <0 .05) .Conclusion Strict breathing training and good breath effect will reduce motion artifacts in CTA ima-ging of coronary artery angiography .
