Objective To assess the application of automated four-dimensional (4D) volume color Doppler ultrasonography in normal fetal heart screening. Methods Four-dimensional volume color Doppler was acquired at the level of four chamber view level in 120 fetuses from 18 to 23 weeks of gestation. Three diagnostic planes including color Doppler information were retrieved by automated multiplanar imaging from the 4D volumes. The left ventricular outflow view (cardiac plane 1), the right ventricular outflow view (cardiac plane 2) and ductal arch view (cardiac plane 3) were acquired. Tomographic ultrasound imaging (TUI) was added to display all the three diagnostic planes. The data were then analyzed to determine whether cardiac planes 1-3 were displayed correctly in each volume. Results Automated 4D volume color Doppler ultrasonography displaying rate of cardiac plane 1, cardiac plane 2, cardiac plane 3 were 100%, 96.67% and 91.67%, respectively. Cardiac plane 1 was displayed at least three TUI plane, cardiac plane 2 was displayed at least two TUI plane, and cardiac plane 3 was displayed at least two TUI plane. Conclusion It is possible to acquire important planes of the fetal heart with automated 4D volume color Doppler ultrasonography and the visualization rate of the three diagnostic planes is fine.

Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ~2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P＜0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography.
