Chronic hypoxia during the gestation period (hypoxemia) can cause the neuronal death and slow neural migration in the developmental brain. This study aims to investigate the effects of chronic fetal hypoxia on postnatal guinea pigs in the developing brain longitudinally using in vivo MRI of T2 maps, DTI and volume measurements. DTI and T2 measurements suggest delayed axonal myelination and tissue maturation during development of neonatal guinea pigs that experienced chronic fetal hypoxia.
