Title: 16 slice CT Evaluation of Anomalous Origin of the Coronary Artery from the Pulmonary Artery
Abstract: Objective To evaluate the value of 16 slice spiral CT in diagnosis of anomalous origin of the coronary artery from the pulmonary artery.Materials and Methods 8 children (mean age 4.12 years,age range 5 month to 10 years) with anomalous origin of the coronary artery from the pulmonary artery were studied by 16 slice CT.Multi slice CT (MSCT) with or without ECG gating was performed in 4 cases respectively.Parameters included:gantry time 0.5s,collimation 0.625~1.25mm,thickness 0.625~1.25mm,pitch 0.562,and reconstruction interval 0.31~0.625mm.Results The percentage of visibility was 100% for the left main coronary artery,proximal segment of the left descending and left circumflex coronary artery,and origin and proximal segment of the right coronary artery.There were 7 cases with anomalous origin of the left coronary artery from the pulmonary artery,1 case with right coronary artery arising from the main pulmonary artery.Of the 8 cases,1 case was associated with partial anomalous pulmonary venous return,1 case with high takeoff of the right coronary artery.Conclusion Anomalous origin of the coronary artery from the pulmonary artery is a rare congenital heart disease,MSCT can be considered as a non-invasive and reliable imaging technique for diagnosis of congenital coronary artery anomaly.
