摘要
目的 探讨磁敏感加权成像(SWI)在诊断新生儿颅内出血中的应用价值。资料与方法搜集新生儿重症监护病房的97例患儿头颅MRI常规序列(T1WI、T2WI)和SWI序列的扫描资料。结果 97例新生儿SWI共检出46例颅内出血,MRI常规序列仅检出其中的36例;SWI共检出脑内出血灶104个,MRI常规序列仅检出19个。结论 较常规MRI序列,SWI在检出新生儿颅内出血的阳性率、数目、体积大小方面有着明显的优势,是探查新生儿颅内出血一种非常好的MR新技术。
Objective To explore values of SWI in detecting neonatal intracranial hemorrhage（NICH）.Materials and Methods Ninety-seven neonates underwent conventional MRI（T1WI,T2WI）and SWI examination.Results Forty-sixcases were found NICH in SWI,and only 36 of 46 cases were found in conventional MR sequences.Altogether 104 hemorrhagic lesions were detected on SWI images versus 19 lesions revealed on routine MRI images.Conclusion Compared with conventional MRI,SWI is an excellent new MR sequence for the diagnosis of NICH and the detection of hemorrhagic lesions.
