The epidemiologic study of premature infant brain injury diagnosed by magnetic resonance imaging

Backgound: Perinatal brain development undergoes dramatically changing in human life. Multiple insults in perinatal period such as hypoxia or and ischemia, infection and inflammation often cause different severity and patterns of brain injury such as ischemic injury or hemorrahgic injury. To explore the epidemiological rule and correlated risk factors of premature infant with brain injury we used MRI findings to define the diagnosis of brain injury. Methods: The study was prospectively performed on 358 preterm infants from 2008 to 2011at the neonatal intensive care unit of Shengjing Hospital of China Medical Uni…
