Ultrasound diagnostics during pregnancy is the main method of monitoring fetal development. High-frequency sounds are reflected from tissues and form an image on the screen. Modern 3D and 4D ultrasound technologies provide much more information than a standard examination. They make it possible not only to assess the fetal anatomy with high accuracy, but also to see a three-dimensional image of the baby in real time.
For expectant parents, 4D and 3D ultrasound is a combination of diagnostics and emotional experience that helps them get to know their child even better.
3D and 4D ultrasound: what is the difference between the methods
Standard 2D ultrasound is a basic method of examination during pregnancy that shows a two-dimensional (flat) image of internal structures. It is used to assess the development of the fetus, determine the gestational age, the position of the child, and identify possible defects.
3D ultrasound generates a three-dimensional image that allows you to examine in more detail the external features of the fetus – face, limbs, body contours. This examination method is important both for clarifying certain anatomical features and for a more visual representation of the child’s appearance.
4D ultrasound is actually the same 3D image of the baby, but in real time. That is, you can see the fetus’s movements: how it moves its arms and legs, changes its facial expressions, opens its mouth, or reacts to touch.
The main difference between these types of ultrasound is:
- 2D flat image for basic diagnostics;
- 3D – a three-dimensional picture (static image);
- 4D – three-dimensional image in motion (real-time video).
3D and 4D ultrasound complement the standard examination, providing more visual information and emotional contact with the unborn baby before it is born.
When is it better to have a 3D and 4D ultrasound during pregnancy?
Ultrasound examination is a safe diagnostic method, so it can be performed any number of times during pregnancy for medical reasons. At the same time, according to the medical protocols of pregnancy management, there are recommended timing of screening examinations:
- The first ultrasound. It allows you to confirm the fact of pregnancy, set the due date and check the implantation of the fetal egg in the uterus.
- First prenatal screening (11-13 weeks +6 days). It is carried out to confirm the viability of pregnancy, determine the exact due date, and assess the main anatomical structures of the fetus. Indicators are measured (for example, cervical space) to help assess the risk of chromosomal abnormalities, and the condition of the amniotic fluid and placenta is assessed.
- Prenatal screening of the second trimester (18-21 weeks). During the second trimester of pregnancy, a detailed examination of the fetal anatomy is performed: internal organs and systems (heart, brain, spine, internal organs) are assessed, and congenital malformations are excluded. The sex of the child can also be determined at this stage.
- III trimester (30-32 weeks). The doctor is interested in the growth and development of the fetus, its position, the amount of amniotic fluid, the condition of the placenta and blood flow, which is important for planning the delivery tactics.
- The last ultrasound examination. It is performed at 37-42 weeks, when the pregnancy is considered full-term and the doctor needs to clarify the position and weight of the fetus, the condition of the placenta, and the volume of amniotic fluid to plan the delivery.
4D and 3D ultrasound during pregnancy can be performed as part of these examinations or additionally, depending on the purpose. When it comes to medical diagnosis, the doctor determines the optimal period individually.
Please note! If the goal is to get a clear image and emotional contact with the baby, the best time to do it is between 24 and 32 weeks of pregnancy. At this time, the fetus is already sufficiently formed, but still has enough room for movement to obtain clear three-dimensional images during the ultrasound.
Indications for 3D and 4D diagnostics
3D and 4D ultrasound are used not only for emotional acquaintance with the baby, but also have clear medical indications. These examination methods allow for a more detailed assessment of the fetal anatomy and refinement of standard ultrasound diagnostics.
Main indications:
- Suspicion of congenital malformations (especially of the face, limbs, spine);
- the need for detailed visualization of fetal anatomical structures;
- clarification of 2D ultrasound results in case of doubtful or uninformative data;
- assessment of the fetal condition in case of complicated pregnancy;
- preparation for or monitoring of assisted reproductive technologies (including IVF protocol );
- the psychological need of parents for closer emotional contact with their child.
In each case, the expediency of 3D or 4D ultrasound is determined by the doctor, taking into account the course of pregnancy and individual characteristics.
Diagnosis and the first ultrasound image of the child
The first clear picture of the baby is a moment that will be remembered forever. Thanks to 3D ultrasound, you can see three-dimensional facial features, body contours, small hands and feet even before the birth of the long-awaited baby.
In the 4D ultrasound mode, the ultrasound image of the baby comes to life: you can observe how it moves, smiles, opens its mouth, touches its face or reacts to external stimuli. This format allows you not only to assess the condition of the fetus, but also to feel the real emotional connection between mother and child during gestation.
What is better to choose: conventional or 4D ultrasound?
The choice depends on the purpose of the examination. Conventional 2D diagnostics is a routine procedure during pregnancy. It provides the doctor with basic information about fetal development, heartbeat, condition of organs, placenta, and the course of pregnancy in general.
4D ultrasound does not replace the standard examination, but complements it. It allows you to see a three-dimensional image of the child in motion, better assess the external structures and get a more visual idea of the baby’s appearance. If you have any doubts, an IVMED gynecologist will tell you in detail about the features of the methods during the consultation and help you make the best choice in your particular case.
How does the 4D examination take place at the IVMED clinic
4D ultrasound is performed in a comfortable environment and does not differ in sensations from a standard ultrasound examination. The examination at the IVMED clinic is performed by a qualified doctor using modern equipment, which allows you to get a clear three-dimensional image of the fetus in real time.
Sequence of ultrasound diagnostics:
- A pregnant woman is sitting on a couch;
- a special gel is applied to the abdomen for better contact of the sensor;
- the doctor performs the scan, assessing the condition of the fetus and simultaneously displaying a 3D or 4D image on the screen;
- when using the 4D method, the patient can observe the child’s movements in real time;
- based on the results of the diagnosis, a conclusion and a photo or video of the baby are provided.
4D examination is based on the same ultrasound waves as standard ultrasound, so it is safe for mother and child. The method is not accompanied by radiation exposure and is widely used around the world to monitor the course of pregnancy.
