目的:研究早产儿脑病的磁共振(MR)影像学表现及危险因素。方法:选取2014年2月-2015年2月在本院分娩的早产儿脑病患儿36例作为观察组,另选取同期早产无脑病患儿36例作为对照组,研究早产儿脑病患儿的MR影像学表现及危险因素。结果:经头颅MR检查,对照组36例早产儿结果正常,观察组36例患儿中,单纯的早产儿脑病患儿占91.7%,其他类型的脑损伤患儿占8.33%。早产儿脑病发病以非囊性为主占77.8%,囊性病例占13.9%,脑室周围白质存在损伤患儿占41.7%,脑叶白质发生病变患儿占58.3%。导致患儿发病的危险因素为阴道助产、用氧时间、多胎之大、体重、真菌败血症,与早产正常儿比较,差异具有统计学意义(P<0.05)。结论:对早产儿脑病患儿实施MR影像学检查,能够明确病因,找出危险因素,便于患儿能够及时得到诊断和治疗
PURPOSE: To study magnetic resonance (MR) imaging findings and risk factors for encephalopathy in preterm infants. Methods: Thirty-six children with encephalopathy at delivery in our hospital from February 2014 to February 2015 were selected as the observation group. Another 36 children with encephalopathy without premature ejaculation were selected as the control group. Imaging findings and risk factors. Results: In the 36 cases of preterm infants in the control group, the result of the MR examination in the control group was normal. Among the 36 children in the observation group, 91.7% of the children were diagnosed as having premature encephalopathy alone and 8.33% of the other types of brain injury. The prevalence of encephalopathy in preterm infants was 77.8% with non-cystic disease, 13.9% with cystic disease, 41.7% with periventricular white matter damage, and 58.3% with cerebral white matter lesions. The risk factors leading to the incidence of children were vaginal delivery, oxygen time, multiple births, weight, fungal sepsis, compared with normal premature children, the difference was statistically significant (P <0.05). Conclusion: MR imaging examination of children with encephalopathy in preterm infants, can clear the cause, identify risk factors, to facilitate the timely diagnosis and treatment of children
