| 摘 要： | 目的：评价MRI对新生儿缺氧缺血性脑病（HIE）的诊断价值。资料与方法：采用SE序列对61例（65例次）HIE患儿进行了MRI检查，分析MRI表现。结果：56例新生儿期检查中脑水肿42例，内囊后肢信号异常22例，脑出血11例，脑室出血4例，脑室旁白质软化2例。9例婴儿期检查者中表现有脑室扩大7例，脑外间隙增宽9例，髓鞘发育延迟3例。结论：MRI有助于明确HIE的脑损伤情况，对于预后的评估有价值。

| Abstract: | Objective To evaluate MRI in the diagnosis of hypoxic-ischemic encephalopathy (HIE) in the neonates and infants.Materials and Methods Using SE sequences, MRI was performed in 61 cases with HIE. MRI findings were analyzed.Results Of 56 cases during their neonatal period, brain edema was seen in 42, abnormal signal at posterior limb of internal capsule in 22, cerebral hemorrhage in 11, intraventricular hemorrhage in 4, and periventricular leukomalacia in 2. Of 9 cases during their infantile period, dilated ventricle was seen in 7, increased extracerebral space in 9, and delayed myelination in 3.Conclusion MRI is helpful for evaluating brain injury and predicting prognosis in neonates with HIE. |
