摘 要 目的 ：以胎儿头颅断层解剖为基础,研究颅脑声像图特征。方法 ：对6例妊娠20～30周胎儿引产后作颅脑断层解剖与产前声像图对照分析。结果 ：(1)声像图颅内远场:“无回声区”并非脑脊液积聚所致;(2)蛛网膜下腔宽度与双顶径之比(SD/BPD)随孕龄增加而缩小。结论 :研究胎儿颅脑断层解剖是提高超声诊断的理论依据。

ABSTRACT Objective: Tostudy the characteristics of ultrasonography of fetal brain and cavum subarchnoid spacebased on the slice anatomy of fetal heads.Methods： Theechoencephalograms of 6 induced labor fetuses at 20-30 weeks gestation and the sliceanatomy of fetal brains were studied.Results: (1)Anechoic area of the farfield of the fetal head is not liquor cerebrospinalis actually; (2)Subarachnoid ratioactual distance /biparietal diameter is reduced as pregnant weeks rise.Conclusion: Theslice anatomy of fetal brain is the theoretical basis for ultrasonographic diagnosisimprovement.
