摘　　要：目的:分析二维颅脑横切面法联合Omniview技术在超声筛查胎儿胼胝体中的诊断价值。方法:回顾性分析2023年2月—2024年3月在临沂市妇幼保健院检查的116例孕妇的临床资料,所有孕妇均行二维颅脑横切面法联合Omniview技术筛查胎儿胼胝体,分析相关数据。结果:116例胎儿中,孕周20~25周38例,孕周26~30周33例,孕周31~35周25例,孕周36~40周20例;通过直线回归和线性相关分析,发现胎儿胼胝体各径线值与枕额径呈线性正相关关系。具体相关系数如下:胼胝体膝部0.840、胼胝体前体部0.600、胼胝体前中体部0.640、胼胝体后中体部0.670、胼胝体峡部0.700、胼胝体压部0.810、胼胝体前后径0.950;116例胎儿中,超声显示55名为男胎,61名为女胎。通过对比分析七组不同部位的径线值,结果显示男胎组和女胎组之间在胼胝体厚度及前后径线值方面差异无统计学意义(P>0.05),即胼胝体的厚度和前后径线值与性别无关。结论:二维颅脑横切面法联合Omniview技术是一种简单快速地筛查胎儿胼胝体的方法,在提高诊断效能的同时,能更有效地进行胎儿神经系统的评估和诊断,为胎儿神经系统异常的早期发现提供了有益的信息。Objective To analyze the diagnostic value of two-dimensional cross-sectional combined with Omniview technology in ultrasound screening of fetal corpus callosum.Methods The clinical data of 116 pregnant women examined in Linyi Maternal and Child Health Hospital from February 2023 to March 2024 were retrospectively analyzed.All pregnant women were screened fetal corpus callosum by two-dimensional cross-sectional combined with Omniview technology,and the relevant data were analyzed.Results Among 116 fetuses,38 fetuses were 20-25 weeks,33 fetuses were 26-30 weeks,25 fetuses were 31-35 weeks and 20 fetuses were 36-40 weeks.Linear regression and linear correlation analysis showed that the diameters of corpus callosum were positively correlated with occipitofrontal diameters.The specific correlation coefficients were as follows:knee of the corpus callosum 0.840,precursor of the corpus callosum 0.600,anterior midbody of the corpus callosum 0.640,posterior midbody of the corpus callosum 0.670,isthmus of the corpus callosum 0.700,compressive part of the corpus callosum 0.810,anterior and posterior diameter of the corpus callosum 0.950.Of the 116 fetuses,ultrasound showed 55 were male and 61 were female.Through comparative analysis of the diametral values of different parts of the seven groups,the results showed that there were no significant differences in corpus callosum thickness and anterior and posterior diametral values between the male and female fetal groups(P>0.05),that is,the thickness and anterior and posterior diametral values of the male fetal group and the female fetal group were not correlated with gender.Conclusion Two-dimensional cross-sectional combined with Omniview technique is a simple and rapid method for screening fetal corpus callosum,which can improve the diagnostic efficiency and evaluate and diagnose the fetal nervous system more effectively,providing useful information for the early detection of fetal nervous system abnormalities.
