摘　　要：目的通过观察新生儿颅内出血在磁敏感加权成像(SWI)与超声检查中的表现,探讨SWI ESWAN序列与超声在新生儿颅内出血中的诊断价值。方法采用ESWAN序列、常规MRI序列及超声对150例新生儿进行检查,比较三者对新生儿颅内出血的检出率、分布区域及病灶检出个数之间的差异。结果 ESWAN、常规MRI序列及超声对新生儿颅内出血的检出率分别为32.7%、25.3%和22.0%,且均以室管膜下-脑室内(SEH/IVH)出血发生率最高。三者对新生儿颅内出血的检出率的差异具有统计学意义(P<0.05),ESWAN序列对病灶的检出率明显高于超声;对于出血灶检出个数ESWAN序列明显高于常规MRI序列。结论 ESWAN序列对新生儿颅内出血的检出率明显高于超声检查,可作为新生儿颅内出血诊断的必要补充。Objective Through the observation of magnetic susceptibility weighted imaging （ESWAN）and ultrasound in intracranial hemorrhage in the newborn,and objective to discuss the diagnostic value of ESWAN and B ultrasound in intraeranial hemorrhage in the newborn.Methods One hundred fifty cases of neonatal intracranial hemorrhage cases were detected by using ESWAN sequence,conventional MRI sequence and B-mode ultrasonography.The detecting rate,distribution and number of intracranial hemorrhage were compared among those three methods.Results The detection rates of intracranial hemorrhage ESWAN,conventional MRI sequence and ultrasound were 32.7％,22％,25.3％ respectively.Subependymal intraventricular hemorrhage was the most common hemorrhage（SEH/IVH）,there was statistical difference（P ＜ 0.05）.The detection rate of ESWAN sequence was significantly higher than that of B ultrasound and the detection rate of ESWAN sequence was higher than that of conventional MRI sequence for the bleeding lesions.Conclusion Compared with ultrasound,ESWAN has obvious advantages in the diagnosis of neonatal intracranial hemorrhage,it can be used as an essential supplementary examination in the diagnosis of intracranial hemorrhage of the newborn.
