Three-dimensional magnetic resonance imaging of fetal head molding and brain shape changes during the second stage of labor
Fig 5
Three-dimensional fetal brain MRI reconstruction before labor (shown in purple in A, C, E) and during the second stage of labor (shown in orange in B, D, F). In all patients, the fetal brain was observed to change in shape in the second stage of labor. This change in fetal brain shape mirrored the shifting of fetal skull bones observed during the second phase of labor.
