Figure 1:

Segmentation of fetal brain structures. Twenty-eight individual structures were segmented and refined for all fetuses, and for fetuses less than 31 weeks of gestational age, the fetal white matter transient zones were additionally segmented. Image shows two-dimensional axial fetal segmentations for (A) a 25-week-old fetus and (B) a 36-week-old fetus, as well as (C, D) the three-dimensional volumetric segmentations (C corresponds with A, and D with B). A color bar is shown with labels for all structures.
