title: [Imaging of congenital coronary artery anomalies by dual-source computed tomography angiography].
abstract: OBJECTIVE
  To investigate the value of dual-source computed tomography (DSCT) angiography in the examination of congenital coronary artery anomalies.
  
  
  METHODS
  We retrospectively examined 2530 patients by DSCT angiography between January 2008 and September 2010. Congenital coronary artery anomalies were shown by maximum intensity projection, curved planar reconstruction, and volume rendering.
  
  
  RESULTS
  A total of 284 segments with congenital coronary artery anomalies in 225 patients were displayed. The anomalies included those originated from the main branch of coronary artery (n=121, including 35 segments of right coronary artery with high take-off origin and 24 segments of left coronary artery, 17 segments of right coronary artery dated from left aortic sinus, 4 segments of left coronary artery dated from right aortic sinus, 2 segments of left coronary artery dated from posterior aortic sinus, 2 segments of single coronary artery, and 37 segments of para-coronary artery) , coronary artery dysplasia (n=18) , coronary artery fistula (n=9, including 4 segments of right coronary artery-right ventricle fistula, 2 segments of right coronary artery-pulmonary artery fistula, 2 segments of left coronary artery-left ventricle fistula, and 1 segments of left coronary artery-pulmonary artery fistula) , and myocardial bridge (n=136) . In addition, 818 segments of left sinuatrial nodal artery original anomalies in 1720 patients whose sinuatrial nodal artery were well shown.
  
  
  CONCLUSIONS
  DSCT can be helpful in detecting the anomalies of coronary artery.
