Conventional (2D) ultrasound allows you to see a two-dimensional image on the monitor: in transverse and longitudinal lines. On its basis, the computer calculates the volume of a given organ or lesions on it (e.g. tumor, polyp).
The latest technological solutions allow you to create an image using 3D technology – thanks to which gives data on 3 dimensions: length, width and observed depth of an object. In this case, the computer compiles the data, recreating the three-dimensional image of the measured structure, making it possible to examine it as thoroughly as possible.
4D ultrasound is an even more advanced technology – a camera, thanks to a computer, recreates the image obtained with the 3D technique in a dynamic way – thanks to which a moving image is obtained, resembling a video record. This type of examination is performed on pregnant women so that they can see the fetus in motion on the monitor screen.
The test record – which the patient receives – can be recreated and analyzed many times by the doctors In addition, it enables a precise assessment of individual anatomical structures. For a woman, however it is also an attractive souvenir – a record of her baby’s first movements. In turn, made with the 3D technique photos usually end up in family albums and are a source of great emotions.
3D and 4D ultrasound examinations are recommended especially in the case of multiple pregnancy – due to the ability to accurately visualize all fetuses, their location in relation to each other, assessment of the placenta and amniotic. These are also tests that most effectively detect potential fetal defects – allowing you to obtain an infinite number of sections and the most accurate images.
If there are no contraindications, 3D and / or 4D ultrasound is recommended for every future mother between 18 and 22 weeks of pregnancy.
