Abstract: Objectives To investigate the diagnostic value of neonatal behavioral neurological assessment (NBNA) and magnetic resonance image (MRI) in the newborns' brain injury with severe hyperbilirubinemia. Methods 20 cases of newborns with severe hyperbilirubinemia brain injury were admitted between Sep.2013 and Sep.2015 as the research objects.MRI result was further analysised after using NBNA score and MRI.The control group (n=20) who were normal newborns accepted the examination of NBNA.Subsequently,the NBNA scores of the two groups was analysised.The infants with MRI signal abnormality were rechecked at the age of 6 months. Results The NBNA scores of research objects were significantly lower than that of control group.In the 20 cases,9 cases with MRI signal abnormality and 11 cases without any pallidum signal changing.The NBNA scores of the abnormal MRI group were lower than that of the normal group.And there were no abnormal signals when recheck in their 6 month. Conclusions MRI scans is particularly important during the diagnosis of the newborns' brain injury.The NBNA score and head MRI can be used as the index of early diagnosis for brain injury in newborns.
