The purpose of this study is to collect and compare information from cranial ultrasounds, magnetic resonance imaging scans, neurological exam and neuropsychological assessments of children. The investigators hope that the information collected in this study will help with early screening, diagnosis and treatment of brain injury in newborns as well as identify a connection between MR imaging (MRI-magnetic resonance imaging, MRS-magnetic resonance spectroscopy) and neurodevelopmental outcome.
