Objective　To evaluate the diagnosis value of dual source computed tomography on congenital coronary anomalies (CCA) in adults.　Methods　Retrospective analysis was performed on 1824 cases underwent the dual source CT coronary angiography, and the data of patients suffered from CCA were statistically analyzed, for evaluating clinical value of dual source computed tomography.　Results　A total of 43 cases of CCA were found from 1824 cases who undergoing DSCT, giving the detect rate of 2.3% (43/1824), including anomalies of origin of 24 cases (1.3%, 24/1824), myocardial bridge（MB）of 18 cases (0.99%, 18/1824), and abnormal termination of 1 cases.　Conclusions　DSCT can be used to display of anomalous coronary arteries accurately, especially for the diagnosis and prognosis of CCA for outpatients.
