目的：探讨磁敏感加权成像(SWI)对新生儿缺氧缺血性脑病(HIE)临床分度的评价价值。方法回顾性分析40例经临床诊断为HIE患儿的常规MRI及SWI图像，根据SWI有无出血灶以及出血灶的形态、分布、数目进行分组(A、B、C三组)，并与临床分度(轻度、中度、重度)之间应用Kappa一致性检验。结果 SWI共检出颅内出血灶87处，常规T1WI、T2WI及FLAIR检出出血灶仅分别为31、28和48处。SWI分组与临床分度分组一致性较好(Kappa值=0.77，p<0.01)。结论 SWI较常规磁共振扫描可更敏感检出颅内出血灶，并通过观察出血灶的形态、分布及数目有助于推断HIE患儿病情的轻重。

Objective Investigate the evaluation of clinical grading for newborns with hypoxic-ischemic encephalopathy (HIE) by susceptibility weighted imaging (SWI). Methods Analyze the MRI and SWI findings of 40 cases of HIE which diagnosed by clinical criteria in a retrospective way. These newborns were divided into three groups (A, B, C) according to the existence, morphology, distribution and quantity of hemorrhages detected by SWI. Then Kappa test was performed between groups and clinical grading (light, medium, severe). Results A total of 87 intracranial hemorrhages were detected by SWI. Only 31, 28 and 48 hemorrhages were found by T1WI, T2WI and FLAIR sequences respectively. For groups according to SWI findings and clinical grading, the Kappa value of the consistency test was 0.77, p<0.01. Conclusion SWI has higher sensitivity than conventional MRI sequence in detecting intracranial hemorrhage. We can infer the severity in newborns with HIE according to the morphology, distribution and quantity of hemorrhages detected by SWI.
