The two-dimensional illustration as extended by one dimension for example through the use of ultrasound examinations as part of the prenatal diagnostics during the pregnancy is called a 3-D ultrasound, and also a 3-D sonography.
The three-dimensional imaging enables a spatial illustration of the unborn child, or of individual organs and body parts. The 3-D ultrasound is a special method of ultrasound examination. For the pregnant woman, however, it is no different than other ultrasound examinations. How well the unborn child or its individual organs and body parts can be seen, and whether the sex can also be recognized, depends on special factors such as for example the position of the unborn child, the location of the placenta, the amount of amniotic fluid (in case of smaller amounts of amniotic fluid, the sound is conducted more poorly), the week of pregnancy, and the strength of the maternal abdominal wall.
Determined or suspected bodily peculiarities such as potential heart deficiencies, facial clefts, as well as forms of neural tube deformations, can most often be more precisely analyzed with the 3-D ultrasound.
We combine the 3-D ultrasound images with a measurement of the transparency of the nape of the neck of the unborn child, and the so-called NT screening. In this process, unnecessary amniotic fluid examinations to determine any possible chromosomal disorders are avoided.
