Magnetic Resonance Imaging-Based Reference Values for Two-Dimensional Quantitative Brain Metrics in a Cohort of Extremely Preterm Infants.

Introduction: Cerebral magnetic resonance imaging (cMRI) is an important diagnostic tool in neonatology. In addition to qualitative analysis, quantitative measurements may help identify infants with impaired brain growth. This study aimed to create reference values for brain metrics of various brain areas in neonates without major brain injuries born before 28 weeks of gestation.

Considerable mortality and morbidity in neonates born below 500 gram.

Data evaluating mortality and morbidity in infants born ≤500 g are scarce and show wide variability. To support counselling and decision-making, we analysed neurodevelopmental outcome in all neonates ≤500 g birth weight. Retrospective analysis including preterm infants with a birth weight ≤500 g and a gestational age >22 weeks born at a single tertiary perinatal centre between 2010 and 2017.
