目的:分析胎儿胼胝体缺如产前超声及磁共振诊断的临床应用价值。方法:选取濮阳市安阳地区医院2015年2月至2017年2月产前筛查怀疑胼胝体缺如的64例孕妇,所有孕妇均进行超声检查,超声检查3 d内行磁共振检查,观察比较两种影像学检查对胎儿胼胝体缺如产前检查检出率、检出部位以及胎儿分娩情况。结果:产前超声检查检出43例胼胝体缺如胎儿,磁共振检查检出59例胼胝体缺如胎儿,差异具有统计学意义(P<0.05),磁共振检查胎儿出现胼胝体体部缺如、胼胝体膝部缺如、胼胝体体压部缺如、胼胝体完全缺如以及胼胝体可以缺如的例数明显优于超声检查,差异具有统计学意义(P<0.05),随访发现胼胝体缺如胎儿存活率低,差异具有统计学意义(P<0.05)。结论:对于产妇行产前磁共振检查,能有效提高对胎儿胼胝体缺如的检出率,降低死胎或者先天性缺陷患儿的出生率。
Objective: To analyze the clinical value of fetal corpus callosum, such as prenatal ultrasound and magnetic resonance imaging. Methods: 64 pregnant women suspected of missing corpus callosum in prenatal screening from February 2015 to February 2017 in Anyang District Hospital of Puyang City were enrolled. All the pregnant women were examined by ultrasound and examined by magnetic resonance imaging (MRI) within 3 days after ultrasound examination. Imaging examination of the fetal corpus callosum, such as prenatal examination, detection of the site and the fetus childbirth. Results: 43 cases of corpus callosum were detected by prenatal ultrasound and 59 cases of corpus callosum were detected by magnetic resonance imaging. The difference was statistically significant (P <0.05). There was no significant difference in corpus callosum The absence of the knee, absence of corpus callosum, absence of the corpus callosum, and absence of the corpus callosum were significantly better than those of the ultrasonography (P <0.05). Follow-up revealed that the corpus callosum had a low fetal survival rate , The difference was statistically significant (P <0.05). Conclusion: Prenatal MRI can improve the detection rate of fetal corpus callosum and reduce the birth rate of stillbirth or children with congenital defects.
