目的：评价 MR 磁敏感加权成像(SWI)对新生儿脑实质、脑室、蛛网膜下腔和硬膜下出血的诊断价值。方法收集临床确诊的新生儿缺氧缺血性脑病(HIE)患儿106例，采用3.0T MR 行颅脑常规序列(T1 WI、T2 WI、FLAIR)和 SWI 检查，对比分析SWI 与常规序列对脑实质、脑室、蛛网膜下腔和硬膜下出血检出数目。结果 SWI 检出脑实质出血灶97个，脑室出血灶31个，蛛网膜下腔53个，硬膜下出血12个，常规序列检出脑出血灶41个，脑室出血灶28个，蛛网膜下腔出血38个，硬膜下出血23个。结论 MR SWI 与常规序列联合应用能够提高新生儿颅内出血的诊断。

Objective To evaluate the diagnostic value of susceptibility-weighted imaging (SWI)for the hemorrhage in the brain parenchyma ,brain ventricles ,subarachnoid space ,and subdural cavity in neonate .Methods In this study ,106 cases of hypoxic ischemic encephalopathy (HIE)were collected.All of the patients were scanned with conventional MRI (T1 WI,T2 WI and FLAIR)and SWI. SWI sequence was compared with the conventional MRI sequences in detecting the number of lesions.Results Total of 97 hemor-rhage lesions in brain parenchyma were detected by SWI,31 lesions in brain ventricles,53 lesions in subarachnoid space,and 12 le-sions in subdural cavity.Only 41,28,38 and 23 hemorrhage lesions were found by conventional MRI sequences,respectively. There was statistical significance in the number of hemorrhage lesions between with conventional MR sequences and with SWI.Con-clusion The combination of SWI and conventional MRI may improve the diagnostic accuracy of intracranial hemorrhage in neonate.
