Relationships between early postnatal cranial ultrasonography linear measures and neurodevelopment at 2 years in infants born at <30 weeks' gestational age without major brain injury.

Early postnatal cUS linear measures of brain tissue were related to cognitive and language development at 2 years in infants born <30 weeks' GA without major brain injury. Relationships between cUS linear measures of fluid spaces in the early postnatal period and later neurodevelopment warrant further exploration.
