双源CT在冠状动脉起源异常诊断中的应用

目的：探讨双源CT在先天性冠状动脉起源异常诊断中的应用价值。方法：回顾性分析3550例患者冠状动脉双源CT造影（DSCTA）的结果，判断各种冠状动脉起源异常。结果：3550例患者中，检出冠状动脉起源异常89例，检出率2.50%，包括冠状动脉高位起源31例、多个开口14例、单一冠状动脉5例、主干或分支起自对侧或无冠状窦37例、冠状动脉起自肺动脉2例。结论：DSCTA方便、快捷、无创，是诊断先天性冠状动脉起源异常的有效方法。

Application value of dual-source CT in the diagnosis of coronary artery origin anomalies

Objective：To study the application value of dual-source CT（DSCT） in the diagnosis of coronary artery origin anomalies.Methods：Three thousand five hundred and fifty patients undergone dual-source CT coronary artery angiography（DSCTA）,the data were analyzed retrospectively.Results：Eighty-nine cases（2.50%,89/3550） of coronary artery origin anomalies were detected by DSCTA.The origin anomalies consisted of 31 cases of high takeoff,14 cases of multiple ostia,5 cases of single coronary artery,37 cases of coronary artery or branch from the opposite or noncoronary sinus,2 cases of coronary artery from pulmonary artery.Conclusions： The DSCTA is a convenient,fast,and non-invasive method for detecting coronary artery origin anomalies,and it is an important and effective method for the diagnosis of coronary artery origin anomalies.
