The Comparative Study on TTE,CVDI and EBT in the Diagnosis of Complex Congenital Heart Diseases / 实用放射学杂志

ABSTRACT

Objective To evaluate their roles of transthoracic echocardiography (TTE), cardiovascular digital imaging (CVDI) and electron beam computed tomography (EBT) in the diagnosis of complex congenital heart dieases (CHD).Methods Twenty-one patients with CHD were studied, including 12 cases of boys and 9 cases of girls. Fourteen cases of them underwent surgery. All of them were examined by two-dimensional echocardiography (2DE) , color Doppler flow imaging (CDFI) and EBT, 11 cases of them were examined by CVDI.Results The rate of coincidence between EBT and CVDI in diagnosing complex CHD was 93.3% (28/30). The accurate rate of TTE and CVDI in diagnosing complex CHD was 77.8% (35/45) and 93.3% (42/45) respectively.Conclusion In diagnosing complex CHD,combination EBT with TTE can replace the technique of CVDI partially.
