【摘要】：目的评价超声与磁共振成像(MRI)检查在新生儿胼胝体发育不全诊断中的准确性及应用价值。方法 2012年1月至2014年6月新生儿重症监护室治疗的8 086例新生儿常规颅脑超声筛查,检出胼胝体发育不全确诊及可疑病例31例,对比其MRI检查结果,评价超声诊断准确性。结果 31例新生儿中,超声检查胼胝体完全缺如14例,MRI显示13例一致,1例为部分缺如;超声检查部分缺如16例,脑MRI显示15例一致,1例为无胼胝体;另有1例超声检查为胼胝体异常,MRI显示为部分缺如。MRI显示31例新生儿中合并其他颅脑畸形者14例。结论超声与MRI检查对诊断新生儿胼胝体发育不全具有高度一致性,故前者可作为新生儿胼胝体发育不全的常规筛查手段,后者则能作为新生儿胼胝体发育不良及准确分类的确诊手段,结合二者对临床早期诊断及评估具有指导意义。
[Abstract]:Objective to evaluate the accuracy and value of ultrasonography and magnetic resonance imaging (MRI) in the diagnosis of neonatal corpus callosum dysplasia. Methods from January 2012 to June 2014, 8 086 neonates were screened by routine craniocerebral ultrasound. 31 cases of corpus callosum hypoplasia and suspected cases were detected. The results of MRI were compared and the diagnostic accuracy of ultrasound was evaluated. Results among the 31 newborns, 14 cases were completely absent in corpus callosum, 13 cases were consistent in MRI, 1 case was partially absent, 16 cases were partially absent, 15 cases were consistent in brain MRI, and 1 case was without corpus callosum. The other one was abnormal corpus callosum, and the MRI showed partial absence of corpus callosum. MRI showed 14 of 31 neonates with other craniocerebral malformations. Conclusion Ultrasound and MRI are highly consistent in the diagnosis of neonatal corpus callosum dysplasia, so the former can be used as a routine screening method for neonatal corpus callosum dysplasia. The latter can be used as a diagnostic method of callosal dysplasia and accurate classification of neonatal corpus callosum. The combination of the two methods has guiding significance for early diagnosis and evaluation of neonatal corpus callosum.
