Abstract：Objective To estimate the value of spatio-temporal image correlation for evaluation of double outlet right ventricle .Methods Nine hundred and forty-two pregnant women were tested with spatio-temporal im-age correlation from October 2011 to August 2013 , at the First People′s Hospital in Shangqiu city .The GE voluson 730 expert series color Doppler ultrasound and the volume of the probe were used in the clinical examination of fe -tus in 18-38 weeks of gestation age .The four/five heart′s cavity or blood vessels and long axis plane were observed with some emphasis;the volume data were later treated with GE 4D-viewer 6.2 software.The diagnosis of double outlets of right ventricle was observed according to the standard .Results Totally 28 cases did not attain satisfac-tory volume data due to relatively insufficient amniotic fluid and so on .The volume data of a series of three-dimen-sional imaging in 914 fetus achieved satisfied volume data of perpendicular three-dimensional graphic images through STIC technology ,and the rate of satisfaction was 97.0%, with double outlet right ventricle of six patients , one case with downward displacement of tricuspid valve and one case accompanying with tetralogy of fallot .The correct rate of color Doppler ultrasound in diagnosis of DORV was 100.0%.All the cases had operation .Ventricu-lar septal defect compared with artificial blood vessels slice were used in three cases;arterial switch operation +ventricular septal defect repair were used in two cases and one case had rastelli operation .Conclusion Compared with routine two-dimensional fetal echocardiography , spatio-temporal image correlation can more clearly show the minute anatomy of heart malformation and display the double outlet right ventricle .
