Three-dimensional ultrasonography and assessment of the first-trimester fetus.
We used transvaginal three-dimensional ultrasonography to assess the first-trimester fetus and compared the findings with contemporaneous two-dimensional ultrasonographic studies. Multiplanar three-dimensional ultrasonography provided good visualization of fetal anatomy and allowed fetal measurement and assessment of nuchal translucency thickness. Three-dimensional ultrasonography required significantly less time to perform and to interpret than two-dimensional ultrasonography. Three-dimensional ultrasonography is an effective means of assessing the first-trimester fetus and offers potential advantages over two-dimensional ultrasonography.
