Volumetric MRI and MRS and early motor development of infants born preterm.

Purpose: To investigate the relationship between volumetric magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) in infants born less than 30 weeks gestation and early motor development at 6 months adjusted age.

Methods: Twenty infants born preterm and 4 born at term (control) underwent MRI with volumetric analysis and MRS prior to neonatal intensive care unit discharge. Infants were assessed using the Bayley Scale of Infant Development at 6 months adjusted age.
