目的分析比较CT及MRI诊断新 生儿缺血缺氧性脑病(HIE)的价值。方 法 依据临床通用分度和影像学各自分度 标准，回顾性分析60例HIE临床及CT、 MRI资料，临床和影像分度符合率采用卡 方检验，以P<0.05水准为统计学差异具 有显著性。结果 60例均做了CT检查，其 中25例同时行MRI检查。临床分度：轻度 29例(48.3%)，中度21例(35%)，重度10 例(16.7%)；CT分度：正常7(11.7%)例， 轻度24例(40%)，中度20例(33.3%)， 重度9例(15%)，显示颅内出血21例 (35%)。HIE检出率88.3%。以临床分度为 标准，CT诊断吻合率为82.4%，X2 =10， P=0.019<0.05。MRI检查共25例：轻度 12例(48%)，中度9例(36%)，重度4例 (16%)，显示颅内出血6例(24%)。HIE检 出率100%，与临床分度吻合率达93.5%。 复查CT对轻中度HIE显示率分别为6.5%、 45%，MRI分别为25.3%、58.3%。结论 CT 和MRI检查对HIE的早期诊断、分型及预 后评估有重要价值，MRI优于CT；但蛛网 膜下腔出血检出CT优于MRI。

Objective To compare the value of CT and MRI diagnosis of neonatal hypoxic-ischemic encephalopathy (HIE). Methods Based on clinical and radiographic universal indexing standards, a retrospective analysis of 60 cases of HIE clinical and CT, MRI data was analyzed, The clinical and imaging division compliance rate using the chisquare test, with P<0.05 level for statistical learn the difference was significant. Results 60 cases were all underwent CT, while 25 patients underwent MRI. Clinical grading: 29 mild cases (48.3%) , 21 moderate cases (35%), 10 severe cases (16.7%); CT indexing: normal in 7 cases (11.7%), mild in 24 cases (40%), moderate in 20 cases (33.3%), and severe in 9 cases (15%), 21 cases of intracranial hemorrhage (35%). HIE detection rate of 88.3%. According to clinical grading standard, CT diagnostic agreement was 82.4%, X2 =10, P=0.019 <0.05. MRI examination of 25 cases: mild in 12 cases (48%), moderate in 9 cases (36%), severe in 4 cases (16%), intracranial hemorrhage in 6 cases (24%). HIE detection rate of 100%, consistent with the clinical grading by 93.5%. CT scan of mild to moderate HIE display rates were 6.5%, 45%, MRI were 25.3%, 58.3%. Conclusion CT and MRI have significant value in the early diagnosis, classification and prognosis of HIE, MRI is superior to CT; But CT detection of subarachnoid hemorrhage is superior than MRI.
