3D reconstruction of birthcanal and fetus was obtained from imaging performed with 1T open field MRI before and during childbirth on 10 patients. Fetal head molding and birthcanal changes are fully described in 3D vectorial meshes.  

10 womenwere enrolled in this study in a level I maternity center. Inclusion criteria were normal pregnancy and course of labor in healthy volunteers. A T1 gradient echo sequence was performed, lying on the back, before labor and during childbirth. A Philips 1T Panorama Open field MRI was used. 3D reconstruction was performed with a SIMULACC plateform (babyprogress SAS, France).  

All fetal head molding changes are described, including skull bones movements, meningeal role and brain biomecanical constraints. The birthcanal showed great deformity during the second stage of labor and highlights the biomcecanical process that preludes to human birth.

Obstetrical mechanics are better understood with 3D reconstruction imaging, and this technology opens access to virtual trial of labor in the near future.

Feasibility study of new diagnosis tools using imaging and 3D simulation to help a better management of human birth
