[Abstract] Objective: This study aims to study the neonatal hypoxic ischemic brain damage (HIBD) MRI features.Materials and Methods: 40 HIBD cases were collected. Premature neonates 20 cases and 20 cases full-term neonates, all of them were adept T1WI, T2WI, FLAIR, DWI and SWI multiple sequence scanning in postnatal 10 days. Image analysis and distinguish the major injury type of each HIBD case. The statistical software SPSS 13.0 was used to analysis the impact of gestational age and asphyxia degrees on the injury types.Results: The basal ganglia areas injury 15 cases (preterm neonate 8\full-term neonate 7) is seen in premature and full-term severe HIBD neonates. The pure periventricular white matter ischemic injury 9 cases (preterm neonate 7\full-term neonate 2) is seen in premature and full-term mild to moderate and severe HIBD neonates. The periventricular white matter hemorrhagic injury 5 cases (preterm neonate 5\full-term neonate 0) is most commonly seen in premature mild to moderate and severe HIBD neonates. The cortex and watershed white matter areas injury 7 cases (preterm neonate 0\full-term neonate 7) is seen in full-term mild to moderate HIBD neonates. 4 cases of diffuse brain injury (preterm neonate0\full-term neonate 4) is seen in full-term severe HIBD neonates. The corpus callosum injury 15 cases (preterm neonate 7\full-term neonate 8) is seen in premature and full-term mild to moderate and severe HIBD neonates.Brainstem, cerebellum and hippocampal damage sum to 7 cases (preterm neonate 3\full-term neonate 4) is seen in severe HIBD neonates.Conclusions: HIBD MR imaging has characteristic injury types differences that vary according to the neonates gestational ages and the degree of the severity of the asphyxia.
