Reference ranges for the volumes of fetal cardiac ventricular walls by three-dimensional ultrasound using spatiotemporal image correlation and virtual organ computer-aided analysis and its validation in fetuses with congenital heart diseases

Abstract

The reference ranges for the volumes of the right and left ventricular walls by 3DUS using STIC and VOCAL between 20w0d and 33w6d of gestation were determinate, and they exhibited good intra-observer concordance.
