Abstract:
ObjectiveTo explore the value of low-dose gated dual-source CT(DSCT)in the diagnosis of interrupted aortic.arch.MethodsNine pediatric patients performed DSCT angiography and color Doppler flow imaging(CDFI)in the thoracic aorta and heart.All patients were operated.ResultsDSCT examination was finished in all patients with interrupted aortic arch.Nine patients were associated with ventricular septal defect(VSD),8 patients with patent ductus arteriosus(PDA),2 with bronchus artery dilation and 3 with abnormal origin of the coronary artery.Seven patients were diagnosed as interrupted aortic arch by CDFI,2 patients were diagnosed as truncus arteriosus and coarctation of the aorta respectively.All VSDs and PDAs were detected by CDFI.The diagnostic accuracy of DSCT and CDFI were 94.12%(32/34)and 82.35(28/34)respectively.Conclusion DSCT is a valuable imaging method for the diagnosis of pediatric interrupted aortic arch.
