Quantitative study on the volume of lateral cerebral ventricle in neonates with three-dimensional ultrasonography / 中华超声影像学杂志

ABSTRACT

Objective To study the volume of lateral cerebral ventricle in neonates with threedimensional ultrasonography(3F-US),and to investigate the influence of sex,body weight(BW),head circumference(HC)and gestational age(GA) on it. Methods A total of 255 healthy neonates (GA 28~40 weeks) were examined with 3D cranial ultrasound. The ultrasonography was performed with anterior fontanel as the acoustic window,and the data were aquired at the deck of third ventricle on coronal section.The 3D image on the screen was constructed automatically and the volume of lateral cerebral ventricle was (P=0.809),and there was negative correlation between the volume of lateral cerebral ventricle and GA(r=-0.971). The correlation between the volume of lateral cerebral ventricle and HC was positive(r≥According to the relationships among HC(X 1),GA(X 2)and volume of lateral cerebral ventricle(Y),a linear regression equation Y=2.298-0.011 X1-0.04 X2 was obtained(the determinate coefficient R2 was accurately,which would be helpful to the evaluation on the cerebral maturity and the diagnosis of cerebral desease in neonates without wound.
