Abstract:
ObjectiveTo approach the value of diagnosis with the 256-slice spiral CT in severe tetralogy of Fallot of infant.MethodsFrom January 2008 to December 2010,48 cases (severe tetralogy of Fallot of infant) were examined with 256-slice spiral CT preoperatively.All cases were then analyzed in workspace with maximum intensity projection(MIP),multiplanar reconstruction(MPR) and volume rendering (VR),while compared with transthoracic echocardiography (TTE) and surgical results.Results CT examination found that TTE misdiagnosis 4 cases of patent ductus arteriosus and 6 cases of aortic coarctation.Meanwhile,CT showed 6 aorta pulmonary collateral arteries in 5 cases.In 48 cases,surgical results confirmed 47 cases by 256-shce spiral CT,while 33 cases by TTE.The diagnosis accuracy rate of 256-slice spiral CT and TTE was 97.9％ (47/48) and 68.8％ (33/48) respectively.There was statistically significant difference of the two inspections in diagnostic accuracy (P ＜ 0.05).ConclusionThe inspection of 256-slice spiral CT can benefit the preoperative diagnosis and operation program in severe tetralogy of Fallot of infant.
