摘　　要：目的观察二维和三维超声对胎儿颅缝和前囟的显像价值。方法对80名16～35孕周的孕妇进行二维和三维超声检测,观察胎儿颅缝和前囟,比较两种方法的显示率。结果二维与三维超声对胎儿额缝、人字缝、冠状缝、前囟显示率差异无统计学意义,三维超声对矢状缝的显示率明显高于二维超声。三维超声对颅缝和前囟的完全显示率在孕30周之前与二维超声显示率差异有统计学意义,30孕周之后显像率随孕期增加而下降。结论三维超声能直观、形象地显示胎儿颅缝和前囟的立体形态,对矢状缝的显示率优于二维超声,在30孕周前对胎儿颅缝和前囟的完全显像优于二维超声。Objective To evaluate the feasibility of obtaining good quality ultrasound pictures of sutures and anterior fontanelle with three-dimensional and two-dimensional ultrasound.Methods Eighty fetuses at 16-35 weeks of gestation were evaluated with two-dimensional and three-dimensional ultrasound.The sagittal,coronal,lambdoidal and metopic sutures,as well as anterior fontanelle,were inspected.Results The visualization of the sagittal suture of three-dimensional ultrasound was significantly superior to that of two-dimensional ultrasound,while no significant difference in visualization of the metopic,lambdoidal,coronal sutures and anterior fontanelle was found between the two modalities.The visualization of all sutures and anterior fontanelle was significantly superior with three-dimensional ultrasonography to that of two-dimensional ultrasonography before 30 weeks of gestation,whereas no significant difference was found between the two modalities after 30 weeks of gestation.Conclusion Three-dimensional ultrasound can provide more comprehensive information of fetal cranial sutures and anterior fontanelle than two-dimensional ultrasound does.Three-dimensional ultrasound can also supply high visualization of all sutures and anterior fontanelle before 30 weeks of gestation.
