In
this work we present our methodology to segment central (basal ganglia) and
cortical gray mater of brain in magnetic resonance fetal imaging. This is a
key step in the study of early human brain development. The results for basal
ganglia segmentation are quantitatively validated in 4 cases from 29 to 32
gestational weeks. Cortical brain surface is evaluated qualitatively in a
case study. Our efforts are now in testing such approach on a wider range of
gestational ages that we will include in the final version of this work and
studying as well its generalization to different scanners and different type
of MRI sequences.
