MRI Section of General Hospital of Benxi Iron and Steel Company of Benxi, Liaoning 117000 = Abstract Objective:To study the role of MR imaging in diagnosing neonatal hypoxic-ischemic encephalopathy( HIE) and the correlation w ith clinic.Methods:Sixty-tw o cases of asphyxial perinatal neonates, who were diagnosed HIE by clinic and performed MR imaging, were collected. Results: T -weighted images and T -weighted images w ith fluid-attenuated inversion re- 1 covery ( FLAIR) sequence were significantly superior in T -weighted images with SE sequence in the detection of H IE ( P 0. 05) . HIE w as mostly located in periventricular w hite matter, subependymal, basal ganglia areas in prematures. In full term neonate, however, HIE mostly lay in cerebral cortex and temporal and parietal lobe. There was a partial correlation betw een Ap- gar scores and grading of brain damage on MR images in early HIE and sequela, but not completely correlative each other.And it is also correlative with ages
