摘要
目的 探讨磁共振成像早期诊断早产儿脑损伤的价值及早产儿脑损伤类型.方法 对我院住院早产儿364例,在生后3~7 d行头颅磁共振检查.结果 早产儿脑损伤以缺血性病灶为多见（占76.09%）,最常见是脑白质损伤.出血性损伤以生发基质和脑室内出血为主.弥散加权成像（DWI）对缺血灶的检出率高于常规扫描,比常规MRI能更早地显示早产儿脑白质损伤.结论 磁共振成像对早产儿脑损伤的早期诊断提供了准确的影像学依据.
Objective To observe the value of magnetic resonance imaging （MR1） in diagnosing premature infants with cerebral damage and the type of cerebral damage. Methods MR technology was used in skull examination of 364 cases of premature infants on 3 ~ 7 days after birth in our hospital. Results Ischemia focus was the common symptom in cerebral damage of premature infant, which accoun- ted for 76.09%, and cerebral white matter damage was the most common. Germinal matrix and intraventricular hemorrhage were the main hemorrhagic damage. The detection rate of ischemia focus using diffusion - weighted imaging （DWI） was higher than using conventional scans, and DWI could show cerebral white matter damage of premature infants much earlier than conventional MRI could. Conclusion MRI technology can provide a forceful imaging basis for the early diagnosis of premature infants with cerebral damage.
