摘要
目的:探讨螺旋CT在新生儿缺氧缺血性脑病中的临床价值。方法:2013年2月-2014年2月收治新生儿缺氧缺血性脑病患儿32例,应用64层螺旋进行CT扫描检查。结果:本组32例新生儿缺氧缺血性脑病患儿CT表现为脑质灰白质分界不清,密度降低。CT轻度主要表现为脑白质低密度影,面积≤2个脑叶的脑白质,CT值(18.22±2.56);CT中度主要表现为灰白质界限模糊,少数患儿有颅内出血,面积>2个脑叶,但不累及全部大脑半球,CT值(14.14±2.24);CT重度主要表现灰白质界限消失,多数患儿伴有颅内出血,大脑半球呈广泛性低密度影,CT值(12.56±2.17)。结论:螺旋CT在诊断新生儿缺氧缺血性脑病具有可重复性强、操作简单等优点,值得临床推广。
Objective:To explore the clinical value of spiral CT in neonates with hypoxic ischemic encephalopathy.Methods:32cases of neonates with hypoxic ischemic encephalopathy were selected from February 2013 to February 2014.They all received 64 slice spiral CT scanning.Results:In 32 cases of neonates with hypoxic ischemic encephalopathy,CT showed that brain gray matter boundary was not clear and the density was lower.Light CT mainly showed that the cerebral white matter was low density,the area was not more than brain white matter of two lobes of the brain,CT value was(18.22±2.56).Moderate CT mainly showed that gray matter boundary was fuzzy,a small number of children had intracranial hemorrhage,the area was more than two lobes of the brain,but was not involving the entire hemisphere,CT value was(14.14±2.24).Severe CT mainly showed that gray and white matter boundary was disappearing,the majority of children had intracranial hemorrhage,cerebral hemisphere was widely low density,CT value was(12.56 ± 2.17).Conclusion:In the diagnosis of neonatal hypoxic ischemic encephalopathy,spiral CT has the characteristics of strong repeatability,simple operation and so on.So it is worthy of clinical promotion.
