Abstract：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.
