To investigate the value of dual-source computed tomography (DSCT) angiography in the examination of congenital coronary artery anomalies.
We retrospectively examined 2530 patients by DSCT angiography between January 2008 and September 2010. Congenital coronary artery anomalies were shown by maximum intensity projection, curved planar reconstruction, and volume rendering.
A total of 284 segments with congenital coronary artery anomalies in 225 patients were displayed. The anomalies included those originated from the main branch of coronary artery (n=121, including 35 segments of right coronary artery with high take-off origin and 24 segments of left coronary artery, 17 segments of right coronary artery dated from left aortic sinus, 4 segments of left coronary artery dated from right aortic sinus, 2 segments of left coronary artery dated from posterior aortic sinus, 2 segments of single coronary artery, and 37 segments of para-coronary artery) , coronary artery dysplasia (n=18) , coronary artery fistula (n=9, including 4 segments of right coronary artery-right ventricle fistula, 2 segments of right coronary artery-pulmonary artery fistula, 2 segments of left coronary artery-left ventricle fistula, and 1 segments of left coronary artery-pulmonary artery fistula) , and myocardial bridge (n=136) . In addition, 818 segments of left sinuatrial nodal artery original anomalies in 1720 patients whose sinuatrial nodal artery were well shown.
DSCT can be helpful in detecting the anomalies of coronary artery.
探讨双源计算机断层扫描（DSCT）血管造影在先天性冠状动脉异常检查中的价值。
回顾性分析2008年1月至2010年9月期间接受DSCT血管造影检查的2530例患者。通过最大密度投影、曲面多平面重建和容积再现显示先天性冠状动脉异常。
共显示225例患者的284段先天性冠状动脉异常。异常包括起源于冠状动脉主支的异常（n=121，包括35段右冠状动脉高位起源、24段左冠状动脉、17段起源于左主动脉窦的右冠状动脉、4段起源于右主动脉窦的左冠状动脉、2段起源于后主动脉窦的左冠状动脉、2段单冠状动脉以及37段冠状动脉旁支）、冠状动脉发育异常（n=18）、冠状动脉瘘（n=9，包括4段右冠状动脉-右心室瘘、2段右冠状动脉-肺动脉瘘、2段左冠状动脉-左心室瘘以及1段左冠状动脉-肺动脉瘘）和心肌桥（n=136）。此外，在1720例窦房结动脉显示良好的患者中，发现818段窦房结动脉原始异常。
DSCT有助于检测冠状动脉异常。
