| 目的 探讨儿童缺血缺氧性脑病后遗症脑实质的MRI表现。方法 搜集临床诊断为缺血缺氧性脑病的儿童患者79 例,对其行MRI扫描。结果 根据儿童缺血缺氧性脑病后遗症的MRI影像特点,将其分为：(1)脑白质损伤为主：47 例；①脑室周围脑白质脱髓鞘、软化：23 例；②基底节豆状核、视丘神经元选择性损害：9 例；③胼胝体受损变薄：15 例；(2)脑灰质损害为主：18 例；(3)局部或多处脑软化：9 例；(4)广泛脑损害：5 例。结论 MRI对儿童缺血缺氧性脑病损伤具有高度敏感性,是儿童缺血缺氧性脑病后遗症的最佳诊断工具。 |

| Purpose To explore the MRI manifestation of hypoxic-ischemic encephalopath sequela in children.Methods To collect children who were diagnosed hypoxic-ischemic encephalopath by clinic in 79 cases for MRI scanning.Results According the MRI characteristric of hypoxic-ischemic encephalopath sequela:(1)The most common findings were white matter injury in 47 cases: ①Periventricular leukomalacia in 23 cases;②Selective cerebral neuronal necrosis of basilar node lentiform nucleus and optic colliculus in 9 cases;③Corpus callosum damaged in 15 cases;(2)The most damaged of grey matter in 18 cases;(3)Focal or multifocal ischemic crerbral intenerate in 9 cases;(4)Diffuse crerbral injury in 5 cases. Conclusion MRI is highly sensitive for hypoxic-ischemic encephalopath sequela, and it is the most diagnosis tools of hypoxic-ischemic encephalopath sequela. |
