Our objective is to present our experience of normal embryonic development and fetal anatomy and fetal anomalies reconstructed employing the three-dimensional (3D) and four-dimensional (4D) HDlive rendering mode.
A total of 18 normal embryos and fetuses and 21 abnormal fetuses (one case each of thoracic meningocele, thickened nuchal translucency, multicystic dysplastic kidney, gastroschisis, omphalocele, and ovarian cyst, five of hydrops fetalis, three of skeletal abnormality, three of chromosome abnormality, two of cystic hygroma, and two of amniotic band syndrome) at 7-36 weeks' gestation were studied using the 3D/4D HDlive rendering mode.
In normal fetuses, marked embryonic development with advancing gestation was clearly shown in the first trimester of pregnancy, and various realistic facial expressions were noted in the second and third trimesters. In abnormal fetuses, anatomically realistic features such as gross specimens were obtained. In particular, 3D/4D HDlive provides new, realistic sensations for the diagnosis of amniotic band syndrome, skeletal abnormalities, and facial abnormalities.
3D/4D HDlive rendering images seem to be more readily discernible than those obtained by conventional 3D/4D sonography. 3D/4D HDlive may be an important modality in future embryonic research, fetal neurobehavioral assessment, and the evaluation of fetal anomalies.
我们的目的是介绍我们在三维（3D）和四维（4D）HDlive 渲染模式下重建正常胚胎发育、胎儿解剖结构和胎儿畸形的经验。
共研究了 18 例正常胚胎和胎儿以及 21 例异常胎儿（1 例胸脑膜膨出、颈项透明层增厚、多囊性发育不良肾、腹裂、脐膨出和卵巢囊肿，5 例胎儿水肿，3 例骨骼异常，3 例染色体异常，2 例囊状水瘤，2 例羊膜带综合征），这些胎儿在 7-36 周妊娠时采用 3D/4D HDlive 渲染模式进行研究。
在正常胎儿中，妊娠早期胚胎发育明显，妊娠中期和晚期可观察到各种逼真的面部表情。在异常胎儿中，可获得大体标本等逼真的解剖学特征。特别是 3D/4D HDlive 为羊膜带综合征、骨骼异常和面部异常的诊断提供了新的逼真感觉。
3D/4D HDlive 渲染图像似乎比传统的 3D/4D 超声更易于识别。3D/4D HDlive 可能是未来胚胎研究、胎儿神经行为评估和胎儿畸形评估的重要模式。
