Three-dimensional Reconstruction of Membranous Umbilical Vessels from MR Imaging Assists Delivery Planning

Abstract

We describe 4 pregnancies in which segmentation-based 3D reconstruction was derived from 2D MRI datasets using SYNAPSE VINCENT, which improved spatial understanding of vessel pathways and facilitated identification of vasa previa subtypes during preoperative planning. The reconstructed models qualitatively corresponded with the intraoperative and post-delivery macroscopic findings and assisted in planning uterine incision sites and delivery routes. 3D MRI reconstruction may be clinically useful as an adjunct visual planning tool for selected high-risk pregnancies.
