摘　　要：目的探讨双源CT（DSCT）在诊断成人冠状动脉起源异常（CAOA）的价值。方法回顾性分析2009年1~12月在本院接受DSCT冠状动脉造影检查的3 269例患者资料,对患者图像行最大密度投影（MIP）、容积再现（VR）、多平面重建（MPR）和曲面重建（CPR）后处理,观察冠状动脉起源及走行。结果 3 269例患者中,共检出冠状动脉起源异常37例,检出率为1.13%,其中右冠状动脉起源异常24例（64.86%）,左冠状动脉起源异常13例（35.14%）。所有图像通过不同后处理方法均能显示异常血管的起源及走行。结论 DSCT冠状动脉CT血管造影检查能准确直观地显示冠状动脉的起源及走行,可作为冠状动脉变异的筛查方法。Objective To investigate the values of dual source CT（DSCT） in diagnosis of congenital coronary artery original anomalies.Methods DSCTA data in 3 269 patients were retrospectively analyzed from Jan.to Dec.2009,Maximum intensity projection（MIP）,volume rendering（VR）,multiplanar reformation（MPR）and curved planar reconstruction（CPR）were used to demonstrate the origin and course of the coronary arteries.Results In 3 269 patients,37 patients with congenital coronary artery original anomalies were found,and the detectable rate was 1.13%.There were 24（64.86%）cases of anomalous origin of right coronary artery,13（35.14%）cases of anomalous origin of left coronary artery.Conclusion DSCT coronary angiography is an excellent noninvasive method in the diagnosis of coronary artery anomalies,and it can provide important information for clinical therapy and prognosis.
