Study on the fetal cerebellar vermis using three-dimensional ultrasound VCI-C imaging / 中国基层医药

ABSTRACT

Objective To study the application value of three-dimensional transabdominal ultrasound VCI-C imaging in detection of fetal cerebellar vermis.Methods Totally 300 normal fetuses at 18 ～ 36 gestation weeks were examined by three-dimensional ultrasound VCI-C imaging to observe the fetal cerebellar vermis.Results The view of three-dimensional ultrasound VCI-C imaging well evaluated the integrity and size of vermis morphous,identified characteristic signs of vermisthe fourth ventricle apex and vermis crack.The brain stem and vermis were almost parallel in normal fetus.The angle between them was (3.89 ± 1.58)°.There was no significant relation between the gestational age and the angle.The craniocaudal diameter,anteroposte diameter and acreage of the cerebellar vermis were positively correlated with gestational age.Conclusion The three-dimensional ultrasound VCI-C imaging could help evaluate the development of the cerebellar vermis and show the information of cerebellar vermis and its surrounding structure.It offers a new method to evaluate the fetal cerebellar vermis.
