摘要：

目的　探讨双源CT冠状动脉成像检查对冠状动脉正常解剖及变异的诊断价值。方法　收集2009 年5月至2009年10月行双源CT检查的638例冠状动脉影像资料，分析冠状动脉的正常解剖及变异情况。结果　638例中，左优势型占2.8%（18例），右优势型占89.0%（568例），均衡型占8.2%（52例）。冠状动脉变异占9.4%（60 例），其中，心肌桥32例，右冠状动脉高位开口3例，左冠状动脉高位开口8例，副冠状动脉8例，左主干缺如3例，单一冠状动脉2例，左回旋支冠状动脉瘤1例，无冠窦左房瘘1例，左回旋支起源于右冠状动脉1例，右冠状动脉起源于左冠窦1例。结论　双源CT 冠状动脉成像能准确直观地显示冠状动脉解剖及变异，可作为冠状动脉变异的早期筛查手段。

Abstract:

Objective To discuss the diagnostic value of dual-source CT (DSCT) angiography on detecting coronary anatomy and anomalies. Methods　The coronary artery imaging data of 638 patients who underwent DSCT angiography were reviewed from May 2009 to October 2009. Results　For 638 cases, left-side dominance type was about 2.8%（18 cases）, right-side dominance type 89.0%（568 cases）, balanced type 8.2%（52 cases）. The total of coronary anomalies was about 9.4% (60 cases), which included myocardial bridging 32 cases, RCA high takeoff 3 cases, left coronary artery high takeoff 8 cases, accessory coronary artery 8 cases, absence of LM trunk 2 cases, single coronary artery 2 cases, coronary aneurysm of LCX 1 case, coronary fistula between noncoronary sinus and left atrium 1 case, LCX from RCA 1 case, and RCA from left sinus 1 case. Conclusions　The DSCT can be used to observe coronary anatomy and anomalies accurately, which is a valuable skill to screen early coronary anomalies.
