Keywords: Fetal, Fetus
Motivation: The subcortical nuclei have important brain connectivity, which are rarely studied in fetal brain development.
Goal(s): The aim of this study is to analyze the developmental characteristics of fetal subcortical nuclei and their relationship with gestational age and cortical development.
Approach: The subcortical nuclei and cortical volumes were manually segmented from the three-dimensional (3D) volume parameters of tomosynthesis to volume reconstruction (SVR) images
Results: We found a good linear relationship between subcortical nuclei and gestational age, with agreement on the left and right sides. In addition, we found good coupling between the subcortical nuclei and right cerebral cortex development.
Impact: 3D Volumetric MR to assess the developmental characteristics of fetal subcortical nuclei and their relationship with gestational age. The normative values of fetal intracranial structures across a range of gestations could e used as a reference tool in prenatal counseling.
