Craniocerebral ultrasonography in evaluation on correlation between brain development with gestational age and birth weight of neonatal brain / 中国医学影像技术

ABSTRACT

Objective To explore the value of craniocerebral ultrasonography in evaluation on neonatal brain development.Methods Totally 135 newborns were collected in neonatal intensive care unit.The sagittal length of the corpus callosum and the sagittal length of the cerebellar vermis were measured on the day of birth.The impact of gestational age and birth weight on the development of the corpus callosum and cerebellar vermis were analyzed.Results The mean sagittal length of corpus callosum at birth in premature infants and term infants was (39.18 ± 2.53) mm and (41.62 ± 3.28) mm,respectively (t =4.87,P＜0.05).The sagittal length of cerebellar vermis in premature infants and term infants was (19.03 ±2.00)mm and (20.91 ±2.29)mm,respectively (t=5.05,P＜0.05).The length of the corpus callosum was positively correlated with gestational age and birth weight (rs =0.45,0.51,both P ＜ 0.05),while the sagittal length of cerebellar vermis was positively correlated with gestational age and birth weight (rs =0.42,0.46,both P＜0.05).The length of the corpus callosum was positively correlated with the length of cerebellar vermis (rs =0.43,P ＜0.05).Conclusion Craniocerebral ultrasonography can be used to dynamically observe the neonatal intracranial structure and the development of corpus callosum and cerebellar vermis,therefore providing reliable references for clinical intervention.
