Congenital abnormalities of the coronary arteries are an uncommon but important cause of chest pain and, in some cases of hemodynamically significant abnormalities, sudden cardiac death. For several decades, premorbid diagnosis of coronary artery anomalies has been made with conventional angiography. However, this imaging technique has limitations due to its projectional and invasive nature. The recent development of electrocardiographically (ECG)-gated multi-detector row computed tomography (CT) allows accurate and noninvasive depiction of coronary artery anomalies of origin, course, and termination. Multi-detector row CT is superior to conventional angiography in delineating the ostial origin and proximal path of an anomalous coronary artery. Familiarity with the CT appearances of various coronary artery anomalies and an understanding of the clinical significance of these anomalies are essential in making a correct diagnosis and planning patient treatment.
先天性冠状动脉异常是胸痛的一个不常见但重要的原因，在某些具有血流动力学显著异常的情况下，还会导致心源性猝死。几十年来，一直通过传统血管造影术对冠状动脉异常进行病前诊断。然而，这种成像技术由于其投影性质和侵入性而存在局限性。最近发展起来的心电图（ECG）门控多排螺旋计算机断层扫描（CT）能够准确、无创地描绘冠状动脉的起源、走行和终止异常。在描绘异常冠状动脉的开口起源和近端路径方面，多排螺旋CT优于传统血管造影术。熟悉各种冠状动脉异常的CT表现并了解这些异常的临床意义，对于做出正确诊断和规划患者治疗至关重要。
