摘　　要：为了分析64层螺旋CT（64-MDCT）对成年人冠状动脉变异的表现特征，我们回顾性收集64-MDCT冠状动脉变异患者34例，男性26例，女性8例，平均年龄53．4岁（30～72岁）。对原始数据分别采用多平面重建（MPR）法，最大密度投影（MIP）法，表面阴影遮盖（SSD）法，容积再现（VRT）法进行图像重建。34例冠状动脉变异均清晰显示，右冠状动脉开口于左冠状窦4例，副右冠状窦8例，左前降支和左回旋支分别独立开口于左冠状窦3例，左冠状动脉开口于肺动脉与左冠状动脉高位各1例，心肌桥10例（左前降支9例，左回旋支1例）。右冠状动脉-右心房瘘1例，左冠状动脉-右心室瘘1例，过优势型左冠状动脉3例，冠状动脉瘤2例。因而，04-MDCT可以清晰地、直观地显示变异冠状动脉起源、路径及腔内情况，是一种很好的冠状动脉检查方法。To analyze the adults＇ coronary artery anomalies revealed by 64-MDCT, we retrospectively analyzed 34 eases of coronary artery anomalies （26 males and 8 females, averagely aged 53.4 years with a range from 30 to 72 years）. Multi-plannar reconstruction（MPR）, maximum intensity projection （MIP）, surface shadow display （SSD） and volume rendering（VR） were used to demonstrate the anomalous coronary artery. We found 4 eases of RCA from the left coronary sinus, 8 cases with secondary RCA, 1 case with high locations of left main （LM） segments from left sinus of valves, 1 case with LAD originated from main pulmonary artery, 3 cases with separate origin of LAD and LCX. Ten cases with myocardial bridge were shown （9 cases in LAD, 1 case in LCX） ; coronary fistula was seen in 2 cases （one was RCA-RA fistula, another was LAD-RV fistula）, coronary aneurysm was found in 2 eases. Three eases in RCA were short and small. In conclusion, 64-MDCT is a good choice for diagnosing the anomalous coronary artery.
