【摘要】 目的:通过正常胎儿颅后窝积液即小脑延髓池深度测定,探讨胎儿小脑延髓池深度的正常值范围及与孕周的相关性。方法:在小脑平面对14～42孕周282例胎儿颅后窝积液即小脑延髓池深度进行检测。结果:189例可显示胎儿小脑延髓池深度范围在1～13mm,另93例未充分显示小脑延髓池积液,胎儿小脑延髓池深度与孕周的直线回归方程表明r=0.1174(P>0.05)熏两者无相关性。结论:胎儿小脑延髓池深度与孕周的大小无明显相关性。更多还原

【Abstract】 Objective: To detect the normal value of fetal cerebellomedullary cisternal depth, and its correlation with the gestational age. Method: To detect the depth of cerebellomedullary cistern in posterior cranial fossa at cerebellar plane in 282 gravidas, the range of gestational age was 14～42 weeks. Result: The fetal cerebellomedullary cisternal depths in 189 gravidas were 1～13mm, the fluid in fetal cerebellomedullary cistern was not showed clearly in the other 93 gravidas. The linear regression equation between the fetal cerebellomedullary cisternal depth and the gestational period demonstrated that there was no correlation between them(r=0.1174, P>0.05). Conclusion: There was no correlation between the fetal cerebellomedullary cisternal depth and the gestational age.更多还原
