Feasibility and accuracy of fetal echocardiography using four-dimensional spatiotemporal image correlation technology before 16 weeks' gestation

New Insight from Using Spatiotemporal Image Correlation in Prenatal Screening of Fetal Conotruncal Defects

Three- and four-dimensional fetal echocardiography.

The rapid continuing development of 3-dimensional ultrasound imaging technologies has extended capabilities of fetal cardiac scanning beyond 2-dimensional imaging technologies and now provides a wide array of analytic possibilities. The acquisition of the 3D volume information is based on initial application of 2-dimensional imaging techniques including grey scale, Doppler, Power Doppler and B-...

Feasibility Study on Prenatal Cardiac Screening Using Four-Dimensional Ultrasound with Spatiotemporal Image Correlation: A Multicenter Study

OBJECTIVE This study aimed at investigating the feasibility of using the spatiotemporal image correlation (STIC) technology for prenatal cardiac screening, finding factors that influence the offline evaluation of reconstructed fetal heart, and establishing an optimal acquisition scheme. METHODS The study included 452 gravidae presenting for routine screening at 3 maternity centers at 20-38 ge...

Evaluation of normal fetal ductus venosus using B-flow imaging with spatiotemporal image correlation and traditional color Doppler echocardiography.

OBJECTIVE To explore the feasibility of using four-dimensional echocardiography with B-flow and spatiotemporal image correlation (4DBF-STIC) imaging technology to detect fetal ductus venosus (DV), and establish the normal reference range for the ductus venosus diameter at 18-40 weeks gestation. METHODS This was a prospective observational study to detect the DV in 354 normal fetuses at 18-40 ...
