4D ultrasound is a type of ultrasound you get a sequence of three-dimensional images in 3D. The characteristic is that these images are in motion and in real time, allowing better assess fetal activity. Therefore, the 4D ultrasound is widely used by specialists in gynecology and obstetrics .
4D ultrasound: when to do it?
The 4D ultrasound may be done at any stage in the gestational period comprising from 12 weeks and until well into the third quarter. However, you should perform this type of ultrasound between weeks 24 and 32, and ideally between 26 and 28 weeks.
If the ultrasound is done after 32 weeks, it is likely that the fetus is below the largest diameter of the maternal pelvis and therefore very difficult to obtain images in 3D and 4D.
The patient must go to be tested having anything to eat, that is, avoiding fasting. It is important to avoid skin creams, because they create an interface with the gel used for the ultrasound and this could reduce the quality images.
Advantages of the 4D ultrasound
To perform a 4D ultrasound the same physical principle to perform conventional ultrasound, which is a harmless method for both mother and fetus is used.
The main advantage is that 4D ultrasound allows a very high image quality, which involves assessing possible way of diligent fetal morphology and dynamics as well as the parameters of fetal biophysical profile.
This test accurately visualize large volumes facilitating the detection fetal malformations and assess all the structures surrounding the fetus such as amniotic fluid, umbilical cord and placenta.
All images obtained following the 4D ultrasound are recorded for later to be reproduced to family and friends. Furthermore, it is also useful for other specialists looking images and assess fetal morphological study in order to resolve any doubts.
Perform 4D ultrasound during pregnancy, it does not replace the traditional 2D ultrasound that ised during the first quarter of aneuploid cells for screening. Sustiuye either the 2D ultrasound 20-22 week fetal used for morphological study.
An additional advantage is that it is a lot easier to understand ultrasound for parents, which can signify a plus in the tranquility of both when assessing the integrity and welfare of your child / a, meaning somewhat positive psychological and emotional impact.
