Evaluation of the brain volumes development of fetuses with isolated non-severe ventriculomegaly using MRI

The objective of our study to perform the development of brain volume in fetus with the isolated non-severe ventriculomegaly (INSVM). Then the MRI images of 36 INSVM fetuses and 22 normal fetuses were retrospectively collected, and were manually delineated to obtain quantitative data of brain regions. The gestational age ranged from 26 to 35 weeks. Our study found that the volume development of the basal ganglia, thalamus, and partial white matter in the INSVM fetuses were different from those in the normal fetuses. These differences in the volume development of brain regions need to be determined by expanding the sample.
