摘要
目的 采用Philips 3.0T超导型磁共振扫描仪、美国GE Logiq7超声彩色多普勒诊断仪对HIE患儿进行影像检查及图像分析,探讨颅脑多模态磁共振成像(常规MRI序列联合扩散加权成像DWI及磁敏感加权成像SWI)、颅脑超声在新生儿缺氧缺血性脑病(HIE)诊断中的应用价值及对比研究.方法 回顾性研究分析临床诊断为HIE的患儿56例,分别进行颅脑多模态磁共振成像、超声检查,对比两者发现的病灶例数.结果 颅脑多模态磁共振成像发现蛛网膜下腔/硬膜下出血、脑实质出血、脑梗死/神经元坏死的病例数较超声多,差异有统计学意义(P＜0.05);颅脑多模态磁共振成像发现室管膜下/脑室内出血的病例数较超声少,差异有统计学意义(P＜0.05);颅脑多模态磁共振成像发现脑室周围白质软化/囊变的病例数与超声无明显差异.结论 在HIE诊断中颅脑多模态磁共振成像较超声有一定优势,两者存在互补性.
Abstract
Objective Exploring the application value of conventional magnetic resonance imaging sequences combined with diffusion-weighted imaging(DWI)and magnetic sensitivity weighted imaging(SWI)in the diagnosis of neonatal hypoxic-ischemic encephalopathy,and comparing them with ultrasound diagnosis of neonatal hypoxic-ischemic encephalopathy.Methods A retrospectively analyse was conducted on 56 children clinically diagnosed with HIE,and Number of detected lesions by multimodal magnetic resonance imaging and ultrasound examination of the brain were compared with each other.Results The number of cases of subarachnoidal/subdural hemorrhage,parenchymal hemorrhage,and cerebral infarction/neuronal necrosis was more than that of ultrasound,and the difference has significant statistical significance(P＜0.05).The number of cases of subependymal/intraventricular hemorrhage was less than that of ultrasound by multimodal magnetic resonance imaging of the brain,and the difference has significant statistical significance(P＜0.05).There was no significant difference in the number of cases of periventricular leukomalacia/cystic degeneration on multimodal magnetic resonance imaging of the brain compared with ultrasound.Conclusion Cranial multimodal magnetic resonance imaging has certain advantages over ultrasound in the diagnosis of HIE,and the two are complementary.
