OBJECTIVE
To describe the three-dimensional (3D) sonographic features of nuchal edema in the early second trimester of pregnancy.
METHODS
From 16 to 22 weeks of gestation 5 cases with nuchal edema were studied using transabdominal 3D sonography.
RESULTS
Nuchal edema could be easily imaged with both two-dimensional and 3D sonography; however, visualization of the continuity and curvature of structures was more easily accomplished with 3D sonography. Before 20 weeks of gestation, the skin has a transparent structure, so the bony structures are clearly identified. 3D sonography allowed visualization of nuchal edema in all three dimensions at the same time, providing an improved overview and a more clearly defined demonstration of the adjusted anatomical planes.
CONCLUSION
These results suggest that 3D sonography provides a novel means of visualizing nuchal edema in utero.
目的
描述妊娠中期早期颈部水肿的三维（3D）超声特征。
方法
对妊娠16至22周的5例颈部水肿患者采用经腹三维超声检查。
结果
二维和三维超声均可轻松显示颈部水肿；然而，三维超声更易于观察结构的连续性和曲率。妊娠20周前，皮肤结构透明，因此骨骼结构清晰可辨。三维超声可同时在三个维度上显示颈部水肿，能更好地整体观察，并更清晰地显示调整后的解剖平面。
结论
这些结果表明，三维超声为子宫内颈部水肿的可视化提供了一种新方法。
