摘　　要：目的探讨三维超声在观察胎儿颅缝及囟门结构中的应用价值。方法采用三维超声对100名孕妇(孕龄为16～19+周、20～24+周、25～29+周、30～34+周各25名)进行产前检查,观察胎儿颅缝和囟门结构。结果①矢状缝显示率最低,为53.00%,其他颅缝和囟门的显示率为70.00%～98.00%。②不同孕周胎儿额缝、冠状缝、颞缝、蝶囟、乳突囟显示率差异无统计学意义;而矢状缝、人字缝、前囟、后囟的显示率差异有统计学意义。结论三维超声是观察胎儿颅缝及囟门结构有效的影像学检查手段。Objective To assess the application value of three-dimensional （3D） ultrasound in visualizing fetal cranial sutures and fontanels. Methods One hundred women at different pregnant ages （16—19＋ weeks,20—24＋ weeks,25—29＋weeks,30—34＋weeks,respectively） underwent 3D ultrasound,in order to observe the cranial sutures and fontanels of fetuses. Results ①Most cranial sutures and fontanels （70.00%—98.00%） could be visualized with 3D ultrasound. However,the sagittal suture revealed a lower displaying rate （53.00%） than others. ②At different pregnant ages,there was no significant difference of displaying rate of the metopic,coronal,squamoal sutures and the sphenoid,mastoid fontanels between fetuses and there was significant difference of displaying rate of the anterior and post fontanels,sagittal and lambdoid sutures. Conclusion 3D ultrasound can be used as an effective method for visualizing fetal cranial sutures and fontanels.
