目的：探讨3.0T MRI 磁敏感加权成像(SWI)对足月新生儿缺氧缺血性脑病(HIE)中出血性病灶的诊断价值。方法对临床拟诊 HIE 的63例足月新生儿,采用德国 Siemens 公司3.0T 超导型 MR 扫描仪,行常规 MRI 及横轴位 SWI 序列扫描,比较2种模式下病灶检查及显示情况,并进行相应的统计学分析。结果63例患儿中,SWI 序列共检出29例伴有不同程度的颅内出血,发现151枚病灶,而常规 MRI 仅检出15例伴有颅内出血,其中 T1 WI 发现78枚、T2 WI 43枚、T2 FLAIR 88枚；在出血灶范围及边界清晰度方面 SWI 均明显优于常规 MRI 序列。结论SWI 序列在出血灶的检出及显示方面均明显优于常规 MRI,为临床诊疗提供有力的影像学依据。

Objective To evaluate the clinical value of susceptibility weighted imaging (SWI)in full-term neonatal hypoxic ische-mic encephalopathy (HIE).Methods Sixty-three neonates with HIE were collected and scanned by Siemens 3.0T superconducting MR scanner.Routine axial conventional MRI scan and axial SWI scan were conducted.Results In 63 neonates,a total of 29 cases with different degree of intracranial hemorrhage were scanned with SWI sequence.A total of 1 5 1 intracranial hemorrhages were found.Conventional MRI sequences were performed in 1 5 cases with different degree of intracranial hemorrhage.Only 78,43 and 88 hemorrhages were found by T1 WI,T2 WI and T2 Flair sequences,respectively.SWI were significantly superior to conventional MRI sequences in displaying the scope and boundary definition of hemorrhage.Conclusion SWI sequence is obviously better than the con-ventional MRI sequences in bleeding detection and displaying hemorrhage stove,and it provides a powerful imaging method for the clinical diagnosis and treatment.
