Abstract Objective: To evaluate the role of 64-slice CT in the diagnosis of tetralogy of Fallot and accompanied anomalies. Methods: Twenty-one patients diagnosed as tetralogy of Fallot by 64-slice CT were analysed retrospectively. Toshiba Aquilion 64 was used, slice thickness 0.5mm, overlap 0.3mm. Multi-planar reconstruction(MPR), curved-planar reconstruction(CPR), volume render(VR), maximum intensity projection(MIP) and minimum intensity projection(MinIP) were performed in all patients. Meanwhile, ultrasound echocardiography(UCG) was performed on all patients. Fourteen patients were confirmed by operation, 7 by angiocardiography(ACG). Results: Twenty-one patients were diagnosed by 64-slice CT accurately: pulmonary stenosis, ventricular septal defect, overriding of the aorta and hypertrophy of right ventrical were seen. In the 21 patients, 6 patients had patent ductus arteriosus, 4 right aotic arch, 2 double aortic arch, 7 left superior vena cava, 3 aberrant left brachiocephalic vein, 1 single coronary artery, 3 major aorta-pulmonary collateral arteries. Conclusion: 64-slice CT with 3D reconstruction not only show the anatomical structure of the heart, but also show the coronary and pulmonary arteries. 64-slice CT was an important noninvasive method in the diagnosis of tetralogy of Fallot.
