ABSTRACT
The prognostic significance of cerebral myelination was evaluated with magnetic resonance imaging (MRI) in very low birth weight infants. Myelination was graded in two specified sites, optic radiation and corpus callosum, based on the stages of normal term babies and healthy premature infants. The subjects were 30 preterm infants weighing less than 1,500 gm at birth. MRI was performed at 4 to 7 months (corrected age). The normal myelination stage was seen in 18 cases, while a delayed stage was noticed in 12 cases. In the normal myelination group, only 1 case (6%) had handicaps. In the delayed myelination group, 8 cases (67%) had handicaps. Our results showed that delayed myelination was closely related to a poor prognosis. We believe that MRI would be a very good imaging modality for predicting the outcome of very low birth weight infants, particularly in terms of evaluation of myelination.
