3d And 4d Ultrasound During Pregnancy

3D -4D- the study of the fetus is an additional research method, which is carried out only simultaneously with an ultrasound of the fetus at different stages of pregnancy!

THE PROCEDURE FOR CONDUCTING THREE-DIMENSIONAL AND FOUR-DIMENSIONAL ULTRASOUND OF THE FETUS

Ultrasound of the fetus in 3D and 4D modes can be performed at any time during pregnancy.

If a specialist in ultrasound diagnostics during the ultrasound of the fetus suspects any deviations in its development, then it is imperative to conduct such an additional construction of a three-dimensional image of one or another part of the fetus of interest.

At the request of future parents, the doctor can build an image of the embryo or the face of the fetus in 3D-4D modes.

Future parents need to know that the most favorable time for successful research in 3D-4D modes is 17-18 weeks, i.e. II trimester (13-24 weeks). Success in building a three-dimensional (four-dimensional) image of the fetus depends on the amount of amniotic fluid and the position of the fetus. In the II trimester, the fetus has not yet reached its maximum size, as in the III trimester; the amount of amniotic fluid is enough to build an image.

Amniotic fluid is the acoustic window for successful imaging, and the desired position of the fetus allows you to get the most complete picture. Not always during the entire study, the fetus takes the right position to build a three-dimensional (four-dimensional) image. In this case, during the next screening, you can try to build the image in 3D-4D modes.

An expert study includes an ultrasound during pregnancy of the appropriate period, in the third trimester with the mandatory Doppler study (blood flow in the mother-placenta-fetus system) with the creation of a 3D image of the fetus in 3D and 4d ultrasound test.

Ultrasound findings include:

Ultrasound diagnosis,

Images of the fetus and a disc with the recording of images and mini-video clips that the expectant mother receives on the day the ultrasound is performed.

FEATURES OF 3D AND 4D ULTRASOUND OF THE FETUS

Three- and four-dimensional ultrasound of the fetus is one of the latest ultrasound diagnostic methods that have emerged using modern computer technology. These studies have expanded the possibilities of an objective assessment of the intrauterine development of the fetus and allow it to obtain a three-dimensional image of the baby on the screen of an ultrasound scanner.

For example, with the usual two-dimensional ultrasound, only a specialist can evaluate the “picture” on the monitor screen, while three-dimensional ultrasound allows parents to see the real “photo” of the baby for the first time.

A four-dimensional study is different in that in addition to the volumetric image acquisition of the child (height, width, and depth of the picture), fetal movements can be seen in real-time. That is, a fourth dimension is added to 3D ultrasound - time, which allows you to observe the intrauterine life of your baby.

Recommended dates

An obligatory screening ultrasound examination during pregnancy is carried out three times: at 11 - 14, 18 - 24 and 32 - 36 weeks. An additional study is prescribed if there is evidence and if there are suspicions of possible abnormalities in the development of the fetus and placenta, amniotic fluid pathology and pregnancy. 3d ultrasound and four-dimensional ultrasound is recommended at 17-18 weeks.

Ultrasound Diagnosis During Pregnancy: How Much “D” Is Needed?

Ultrasound has firmly entered our lives. Today, no thorough examination of the body is complete without this type of diagnosis. Ultrasound diagnosis is of particular importance in monitoring pregnancy. It should be at least three times in 9 months for all, without exception, expectant mothers: in the first trimester (11-13 weeks), in the second trimester (19-21 weeks) and the third trimester (30-32 weeks).

But there are already so many ultrasound research formats - 2D, 3D, and even 4D! And all of them are an integral complement to a full and high-quality examination of pregnant women.

When cannot do without 3D?

The research has stated that it is necessary to conduct a 3d ultrasound of the fetal brain for all pregnant women when screening for the first trimester - at 12 weeks. This type of study on changes in the brain allows you to identify severe defects in the spinal cord, namely, Spina Bifida (open spinal cord). At such early times, only 2D scanning may be insufficient, so 3D is an important addition.

In the II-III trimesters, one cannot do without a 3D scan of the fetal brain if it is suspected of defects in its individual structures, such as partial or complete agenesis (absence) of the corpus callosum, transparent septum cavity, and cerebellar worm.

In what cases cannot do without 4D?

4D ultrasound is also an integral part of the examination of the fetus in the II-III trimesters of pregnancy, especially for the diagnosis of facial defects, namely the eyes (the presence of eyeballs in the orbits), cleft lips and palate, the presence or absence of auricles, defects of the nose, extremities, and fingers.

What diagnostic problems can occur during 3D and 4D ultrasound?

The problems with using 3D and 4D for diagnostics are only in the correctness of obtaining 2D slices. This is influenced by many factors: the position of the fetus, the presence of amniotic fluid in the study area, the thickness and density of adipose tissue of the anterior abdominal wall of the uterus, and the qualification of the doctor.

What are the benefits of 4D over 3D ultrasound?

4D allows you to observe the fetus in real-time, to see its movements and even emotions, smile - and this is its main advantage over 3D.

Is 4D ultrasound enough for a doctor to be informative, or is it necessary to do without 2D indicators?

Of course, 2D ultrasound is an integral part of all ultrasound examinations of pregnant women. All other methods only complement it and significantly improve the quality of the study. One of the most powerful ultrasound schools in obstetrics in the world - the Fetal Medicine Foundation - conducts all of its training and certification for doctors based on 2D images and videos.

Are there any contraindications for an ultrasound?

There is no study on the negative effects of pregnancy ultrasound on the human body or fetus. Therefore, there are no contraindications to ultrasound for pregnant women. There are also no restrictions on the number of such studies - they are carried out as much as necessary in each case.

Recommendations Before Doing a 4D or 5D Ultrasound

Are you going to get a 4D or 5D ultrasound and you do not know how to prepare yourself to be perfect? In that case, take note of the recommendations we give you in this post!

Avoid giving you moisturizer 48/72 hours before your ultrasound 4D or 5D

We know that during pregnancy the use of this product in your tummy is essential to take care of the skin. However, you should know that body creams have a fatty film that produces interference in the ultrasound. This influences the quality of the image, making it difficult to visualize your baby. Therefore, this is one of our main recommendations before your 4D or 5D ultrasound.

Try to drink 2 liters of water every day- 3 or 4 days before

Drink plenty of water the days before your 4d ultrasound test will help make the amniotic fluid clearer. Thanks to this, the ultrasound will provide sharper images.

Bring some sweet or exciting drink on the day of the session

Sometimes babies are on their backs or asleep. In order to get them to move and see their faces better, one of our recommendations before your 4D or 5D ultrasound is to take an ounce of chocolate or coffee, as long as the professional advises.

Take 1.5 liters on the day of your 4D or 5D ultrasound and avoid urinating 15 minutes before

In the same way that it is essential to consume fluids before performing a 4D or 5D ultrasound, it is the same day of the session. Also, it would be preferable if your bladder was half full. Therefore, it is advisable to avoid going to the bathroom at least 15 minutes before the 4D or 5D ultrasound. In this way, you are favoring the visualization of the baby.

Wear comfortable clothes and relax

On the day of your 4D or 5D ultrasound, choose items of clothing that you feel comfortable with during the session. A pair of pants that you can undo and a wide blouse with your tummy to the air would be two great options. Remember that the duration of your 4D or 5D ultrasound will be approximately 30 minutes. Therefore, from Forty Weeks we advise you to relax and enjoy this unique experience!

The importance of knowing when to have a 4D or 5D ultrasound

Finally, one of the best recommendations before your 4D or 5D ultrasound is that you choose when to perform it. The week of pregnancy in which you decide to enjoy this experience will be crucial to get the best viewing of your baby. We remind you that as the pregnancy progresses, your baby is located in the pelvic area, which can hinder the visibility of some parts of your body.

Follow our recommendations and enjoy this day

From Forty Weeks we want you to feel comfortable and be able to see your baby as clearly as possible, so it is essential that you follow these recommendations before your 4d ultrasound test. In case it is not possible to see it, do not worry. Our professionals will teach you different exercises to facilitate the movement of the baby, or we will repeat the session without additional cost. Are you ready to live an extraordinary experience?
