Abstract：Objective:To investigate the diagnostic value of dual-source CT (DSCT) coronary angiography in coronary artery anomalies (CAA). Methods:Dual-source CT coronary angiography images and multi-planar reconstruction (MPR), volume render (VR), maximum intensity projection (MIP), curved-planar reconstruction (CPR) images of 357 patients with CAA were retrospectively analyzed. Conventional coronary artery angiography (CAG) was performed in 31 patients.Results:357 cases of CAA were detected by DSCT coronary angiography, including 37 cases of anomalous origin of coronary artery(15 with high origin of coronary artery , 13 with coronary artery originated from the opposite sinus, 7 with LCX originated from left coronary sinus, 1 with LCX originated from right coronary sinus, 1 with single coronary artery), 319 cases of abnormal course with 326 lesions of myocardial bridge(MB), 1 case of abnormal termination with coronary artery fistulas . CAG was performed after DSCT coronary angiography in 31 patients. Among the 27 patients with 29 MB on DSCT coronary angiography, only 21 patients with 22 MB were detected on CAG. All the 3 cases of anomalous origin and 1 case of coronary artery fistulas with DSCT coronary angiography performed were detected on CAG.Conclusions:Dual-source CT coronary angiography can clearly display all kinds of CAA, and it can provide important information for prognosis and operation. It should be selected as the reliable method for follow-up survey.
