A comprehensive and integrated approach to the role of magnetic resonance imaging mri of the brain in neonatology mri is becoming increasingly available to clinicians and has been shown to have major advantages over ultrasound as an aid to diagnosis mri of the neonatal brain mary a rutherford. Noninvasive neuroimaging methods such as mri are essential to establish links between the brain and behavioral changes in newborns and infants. Diffusion mri is another major technique to study the developing brain of newborns and infants as for previous structural approaches it requires optimizing the acquisition parameters and it is exquisitely sensitive to subject motion developmental specificity and methodological challenges. Methods such as mri are essential to establish links between the brain and behavioral changes in newborns and infants
