4D ultrasound during pregnancy

The journey of becoming pregnant is thrilling and full of special moments. Seeing your unborn child for the first time via ultrasound is one of the most memorable pregnancy experiences. Although conventional 2D ultrasounds are widely used, 4D ultrasound provides a far sharper and more comprehensive image.

Parents can view their baby in real time with a 4D ultrasound, capturing remarkably detailed facial expressions and movements. It intensifies the bond even before birth by bringing the baby’s features to life. This technology’s unique experience has led to its increasing popularity.

But in addition to its emotional appeal, 4D ultrasound has some useful medical uses. It can assist medical professionals in keeping an eye on the infant’s growth, identifying specific ailments, and reassuring parents of the child’s wellbeing.

What is it?

This kind of examination is also referred to by doctors as "live" ultrasound. With the use of this most recent technique, ultrasound specialists can see a complete three-dimensional image on the ultrasound machine’s monitor rather than a static one. Expectant parents are increasingly choosing this kind of examination every day. When a 4D ultrasound is performed, fathers and mothers view their child on a monitor; the baby typically moves or makes some motions with his arms or legs. Such a study truly delights expectant parents.

It is important to note immediately that their fetus does not feel happy like this at this point.

Initially, this method of examination was not developed as an entertaining or exciting procedure. Scientists have come up with it to identify difficult to diagnose defects of intrauterine development. Also, with the help of 4D research, it is possible to identify various heart defects, as well as disorders in the functioning of the cardiovascular system of the fetus. During the examination, the doctor examines the uterine cavity, with the fetus in it, from a variety of angles. The device processes the information received from the ultrasound sensor and forms a three-dimensional image on the screen. Such an image is not static. Modern devices can simulate the real movements that the fetus makes in the mother"s womb when the ultrasound sensor is directed at it.

It should be mentioned that not all healthcare facilities are able to perform 4D ultrasounds. The ultrasonic apparatus utilized for these types of tests is typically highly costly. Additionally, the right education and a certain amount of clinical experience are needed to work on it.

Even in private medical facilities, scheduling an appointment with a skilled specialist who performs these kinds of studies is typically highly challenging.

When it is prescribed?

Expectant mothers should keep in mind that only specific medical indications should warrant the use of any type of ultrasound examination, including 4D. There is absolutely no reason to conduct such a test during the normal course of pregnancy. A gynecologist has prescribed this study. For women who have concurrent pathologies or specific diseases of the internal genital organs, 4D ultrasound is typically advised. Therefore, this study will be recommended for the expectant mother if she currently has cardiovascular diseases or if there is a high risk that she will develop them in the future.

Physicians determine a number of the most advantageous times to perform this test during pregnancy. These include the intervals between weeks 20 and 24 and between weeks 30 and 34 of the future baby’s intrauterine development. Reviews from moms who participated in these studies during those periods also support this. They report that they handled the procedure fairly well, experiencing no pain or negative side effects.

Under certain circumstances, research on expert-class equipment is required. This is typically required if a pregnant patient has a complicated pathology that is nearly hard to identify with traditional ultrasonography diagnostic tools.

It’s also necessary to conduct a study with top-notch equipment if the expectant mother is carrying multiple babies at once. After-IVF pregnancy may also be a sign that more precise testing techniques are needed. Expert ultrasonography is frequently utilized in surrogacy.

Expectant parents can view a live, moving image of their unborn child with a 4D ultrasound, giving them the ability to see precise movements and facial expressions in real time. In addition to improving the emotional bond between parents and child, this cutting-edge technology can assist medical professionals in better tracking the growth and well-being of their charges.

How it is carried out?

A 4D study’s methodology differs slightly from that of a traditional ultrasound examination. The examination time is the first notable distinction. Typically, a standard ultrasound takes twenty to thirty minutes. The doctor may need approximately one hour to perform a 4D examination. Usually, the patient receiving examinations lies on her back on the couch. When she is further along in her pregnancy, the examining physician might ask her to turn onto her left side.

Because the inferior vena cava puts less pressure on the uterus in this position, the uterus is much easier to see.

To obtain a high-quality image on the monitor, the patient"s abdomen is lubricated with a special gel. This transparent adhesive substance is necessary for better penetration and reflection of sound waves during the examination. You should not be afraid of it. Its chemical composition is absolutely harmless for both the mother and her future baby. After this procedure, the remains of the gel from the abdomen can be removed with a regular paper napkin or handkerchief. During the examination, the doctor changes the position of the ultrasound sensor in different directions. This allows him to achieve a fairly clear visualization of all parts of the spine, skull, and also examine the vital organs of the baby on the monitor screen.

Additionally, specialists can detect symptoms of a variety of chromosomal and genetic disorders with the aid of 4D ultrasound.

Studying fetal blood flow is also an important issue that interests doctors monitoring the development of the future baby in the mother"s womb. With the help of volumetric ultrasound, it is possible to examine the blood vessels that feed the fetus. Also, during the procedure, various pathologies present in the mother"s body can be detected. It is also possible to assess the work of the baby"s heart with the help of this study. The uniqueness of this test is that it is possible to examine all the structures of the heart, its valves, as well as the coronary vessels. Careful examination of such anatomical structures and detection of pathologies helps to identify various heart defects in a timely manner. Usually in this case a repeat ultrasound is performed, which is carried out in the first days after the baby is born.

Doctors note that with the help of 4D research it is also possible to identify various abnormalities in the structure of the skeleton, as well as developing neurological pathologies. Such pathological conditions include hypoplasia, severe malformations of the neural tube of the fetus, as well as signs of skeletal underdevelopment. The image, which is formed as a result of the reflection of sound waves of a certain frequency, appears on a special monitor. During the examination it is seen by both the doctor and the expectant mother. In the third trimester of pregnancy, not only the baby"s active movements are visible, when he sucks his finger or twists his leg, but also his facial expressions.

The child usually grins or frowns when the ultrasonic sensor is aimed at him.

The appearance of various emotions in a baby can be immediately interpreted. So, the expectant mother believes that if the baby frowns, then he is not well. This is not true at all. Manifestation of emotions in the intrauterine period of development – just a behavioral factor. A pregnant woman should not panic if she sees a grimace of displeasure or pain on the face of her future child. The real emotional background will form in the baby after its birth. A significant advantage of this procedure is the ability to record the image on various electronic media. Future parents can get a video or photo of their baby on a special disk. The photo can also be printed directly in the ultrasound room. Usually, such a first photo of the baby causes tears of joy and genuine delight in future parents.

Regretfully, there are instances when obtaining a high-quality picture or video is not feasible. This frequently happens when a pregnant woman exhibits severe obesity symptoms. A significant quantity of subcutaneous fat obstructs the ultrasound waves’ ability to conduct, which can distort the outcome. It might also be impossible to get a picture of the fetus because of prior uterine surgeries that left scars on the organ.

Another clinical factor that will make it impossible to record the baby’s first "intrauterine" video is the placenta’s high standing.

If the pregnancy proceeds with oligohydramnios, then in this case errors are also possible when trying to capture an image. In such a situation, the picture becomes less clear, the contours of the child acquire blurry outlines. With the help of 4D research, you can also determine the sex of the child. High resolution of expert-class devices allows you to get the most accurate result. Errors in this case are almost never encountered. In case of a twin pregnancy, this method can be used to determine the sex of each baby. Modern devices allow to determine the expected weight, as well as the size of the fetus. Technical errors in such situations practically do not arise. Experienced ultrasound diagnostic specialists can determine the weight of the fetus with an accuracy of a couple of grams. Such a determination is very important, since it indicates how well the future baby is developing in the womb.

Many moms are unsure about which ultrasound technique to use. In this instance, I would like to suggest that you make this decision in consultation with your attending physician rather than on your own. A knowledgeable physician would never recommend a study if it could endanger the unborn child. Expectant mothers should never forget that a basic ultrasound is sufficient to screen for a variety of pregnancy-related pathologies. Studies conducted in 3D or 4D do not substantially differ from one another. Their only distinction is the ability to produce a spatial image.

Parents can see their baby in real time with a 4D ultrasound, which is a unique opportunity that makes for a memorable experience. A unique bond is formed even before the baby is born thanks to the detailed photos, which make it easier to see the baby’s gestures and facial expressions.

Even though 4D ultrasound isn’t always required for medical purposes, it can be a helpful tool for tracking a baby’s development and diagnosing specific conditions. It’s crucial to approach this technology thoughtfully, though, as regular checks can usually be completed with standard ultrasounds.

The decision to undergo a 4D ultrasound is ultimately a personal one. It’s a great option if you’re curious to see your baby up close or if you want a memento. Just make sure it fits with your pregnancy care plan by speaking with your healthcare provider.
