Over the past decade, advances in neuroimaging have given birth to a new field of diagnostic pediatric neurologic assessment that includes magnetic resonance imaging (MRI). This invaluable tool helps medical professionals to resolve many clinical and research questions related to neonatal neurodevelopment that other imaging technology cannot explain. Nurses and others who accompany infants to MRI would benefit from a better understanding of early neurodevelopment and of the neuroimaging procedure. Knowing the advantages and disadvantages of MRI techniques can help nurses be better patient advocates, parent liaisons, and caregivers to infants having MRI scans.
