What is a 3D ultrasound?A 3D ultrasound is a method in which internal organs are visualized three-dimensionally by an ultrasound. The examination itself does not differ in the procedure from a conventional ultrasound examination.
3D ultrasound refers to an ultrasound examination in pregnant women, which visualizes the unborn child three-dimensionally. The recording can be done as a picture or as a video and is often solely the fulfillment of the desire of a pregnant woman for a recognizable ultrasound image or video of the child. The examination itself does not differ in the procedure from a conventional ultrasound examination.
For souvenir pictures and videos, 3D ultrasound is usually made from about the 30th week, as the features and facial features of the child are then easily recognizable. However, the 3D ultrasound procedure can also be used diagnostically much earlier to detect, for example, congenital malformations - the visualization simplifies the diagnosis compared to classical ultrasound. The first 3D images of the child can be made from the 12th week of pregnancy until about the 16th week, if the background is of a diagnostic nature.
For memories offers the investigation from the 25th week on, with some children at this time are not yet well displayed on 3D images. By about the 33rd week, the 3D ultrasound should be performed in any case, since otherwise the unborn child could be too large to be fully displayed on a picture. An image of his face is also possible without further ado.
Function, effect & goals
The main application of 3D ultrasound is the production of easily recognizable memories of the unborn child. If there is no suspicion of malformations, the pregnant woman will be offered the procedure from the 25th week of pregnancy at the monthly check-up. At the 12th to 16th week, the attending physician can detect the child's physical deformities using 3D ultrasound. Heart defects, spina bifida or neural tube defects can be detected at this stage, but chromosomal abnormalities can not be detected with 3D ultrasound.
These must be diagnosed earlier by other procedures. If such an examination has not been made, it is only possible to infer the possible cause of the 3D ultrasound at the basis of physical abnormalities of the child. The result can thus provide clues and arguments for a continued investigation. The internal organs and bones of the unborn child can be visualized.
The application method does not differ from conventional ultrasound. The pregnant woman is applied on the belly lubricant, then the ultrasound device is moved to the right place to recognize the child well. Depending on how it is, it may not be properly recorded for examination - in this case, a new appointment would be made because the doctor can not influence it.
The pregnant woman can determine in good position, which pictures are taken. This is also possible if the doctor carries out a diagnostic evaluation. In this case, the examination may take a little longer until the suspected physical abnormality is well visualized. In addition to diagnostic goals, the doctor may also intend to arouse joy in the child. The tracking of the movements in the abdomen on the 3D ultrasound are displayed in real time and in the second trimester the child is already visible with clear facial features.
Risks, side effects & dangers
Risks are very low with ultrasound examinations. While there is no need to schedule an ultrasound scan more often than recommended in a healthy and normal pregnancy, a 3D ultrasound does not harm the unborn child. The doctor does not exert unnecessary pressure on the pregnant woman's stomach and takes into account the position of the child. If it can not be visualized because it is unfavorable, it will wait until the next examination - its position does not have to change. 3D ultrasound can even make other, much more uncomfortable and riskier examinations unnecessary.
If it is found that the child is physically unremarkable and normal, for example, no samples must be taken or further investigations to be initiated. There are also no side effects, as the ultrasound examination is carried out without physical stress on the pregnant woman and the child and is non-invasive. A special feature compared to the normal ultrasound examination is the dependence on the position of the child. In order to create beautiful memories, the child must face the ultrasound device or at least lie sideways to it. Only for a diagnostic 3D ultrasound, the situation of the child may be less important because the doctor could detect physical abnormalities, even if the child is a little unfavorable.
Unfortunately, one can not influence it, so that in the worst case, a further examination appointment has to be arranged for souvenir pictures. 3D ultrasound not only helps to clarify physical abnormalities or to create souvenir pictures, but can strengthen the early attachment of the parents to their unborn child. Especially in the case of very young parents or difficult pregnancies, doctors are happy to offer a 3D ultrasound that can show parents their children in motion and with recognizable facial features. This can strengthen the awareness of the living being and the growing life in the mother's womb and make parents look forward to their child.
