摘　　要：目的 评价多层螺旋CT血管成像（MSCTA）及重组技术在冠状动脉起源异常（AOCA）诊断中的价值.方法 回顾性分析3856例行MSCTA患者的资料,并对患者原始图像结果进行容积再现（VR）、多平面重组（MPR）、曲面重组（CPR）和最大密度投影（MIP）,观察冠状动脉起源和走行情况.结果 在3856例患者中共检出AOCA患者42例,检出率为1.09%,男女患者检出率分别为1.17% 和0.98%.42例患者中,左AOCA占30.95%（13/42）,其中左回旋支变异9例（69.23%,9/13）;右AOCA占66.67%（28/42）,其中右冠状动脉起源于左冠状动脉窦的患者占35.71%（17/28）.结论 MSCTA及其重建技术能够对 AOCA患者实现无创、快速、准确、直观的诊断.Objective To evaluate the value of multi-slice spiral computed tomography angiography（MSCTA）scanning and reconstruction technology in detecting anomalous origin of coronary artery（AOCA）.Methods Retrospective analysis was done in 3 856 patients who accepted MSCTA.Volume rendering（VR）,multi-planar reformation（MPR）,curved planar reformation（CPR）and maximum intensity projection（MIP）were used to observe the origin and course of coronary artery.Results 42 patients with AOCA were detected among 3 856 objects,and the detection rate was 1.09%.The detection rates had no statistically significant difference between male（1.17%）and female（0.98%）.The rate of patients with anomalous origin of left coronary artery was 30.95%（13/42）, and 9 objects（69.23%,9/13）of them had the anomalous origin of left circumflex.The rate of patients with anomalous origin of right coronary was 66.67%（28/42）,and 35.71% of them（17/28）were found to have the anomalous origin of right coronary artery from the left sinus of valsalva.Conclusion MSCTA scanning and reconstruction technology is noninvasive,rapid,accurate and intuitive.
