During the normal course of pregnancy, ultrasonography (ultrasound) is performed at different periods and the baby is evaluated in terms of development and possible risks. This is called a perinatological evaluation. It is done by trained obstetricians and perinatologists. The ultrasound devices used in these evaluations are quite advanced and provide more detailed and guiding information about the fetus. Detailed ultrasound warns of the presence of disability and/or chromosomal abnormality while the fetus is in the womb. If there is a suspicion of risk, further investigations such as amniocentesis and chorionic villus biopsy can be decided. The condition of the fetus can be clarified while in the womb.
In Which Periods of Pregnancy Is Detailed Ultrasound Performed?
The first of the detailed ultrasound evaluations is done between the 6th and 11th weeks of pregnancy and is called "early pregnancy ultrasound". . In this review, the "actual week" of pregnancy and the "development status of the baby" are examined. In this first detailed ultrasound imaging;
- Number of fetuses (whether the pregnancy is a singleton or multiple pregnancy)
- The presence of internal (ectopic) pregnancy is investigated.
- Feet measurements are made. It is determined whether it develops in accordance with the gestational week.
- Structures in regions such as the heart, brain, great vessel structures, bladder, spine (whether it is closed or not), nuchal thickness (thickness increased in some chromosomal diseases), kidneys, abdominal wall,
- Nasal bone, facial structures and their locations are monitored.
- The placement of the baby's partner (placenta), whether there is enough water, and the suitability of the mother's genital system for pregnancy are evaluated.
For whom is Early Pregnancy Ultrasound Especially Beneficial?
This ultrasound is performed from the 6th to the 11th week of pregnancy and shows the "real week" of pregnancy and the "development status of the baby". It is possible to confirm an ectopic pregnancy. It is useful for pregnant women who have had pelvic pain or bleeding.
What Does Third Level Ultrasound Mean?
The detailed ultrasound examination, known as the second level, is called 3rd level ultrasound with the addition of fetal heart examination. .
Third level ultrasound of pregnancy between 18-23. and the entire body of the baby, such as the brain, face, spine, heart, stomach, intestines, kidneys, hands, arms and legs, is examined from an anatomical point of view.
In most cases, families can be relieved to learn that their babies are developing normally. In addition, high-risk pregnant women and an abnormality that may occur in the baby can be diagnosed beforehand and early treatment can be started.
Why is Four-Dimensional Ultrasonography Performed During Pregnancy?
In this process, sound waves are sent to the tissue with the help of a probe and the sound waves reflected from the tissues are displayed on a screen. that is, the 3D movie image can be viewed in real time, that is, at the time of ultrasound. This is a very exciting technology for families. Studies conducted so far have not found any harmful effects of 2-3-4 dimensional ultrasound on the unborn baby or the mother.
What are the Benefits of Three- and Four-Dimensional Ultrasound?
The baby's movement styles in the mother's womb and It is thought that their behavior may be a symptom of some mental abnormalities that may occur in the womb.
The baby's movements and behaviors can be evaluated with three- and four-dimensional ultrasonography. For example, all these movements such as bringing the baby's hands to its face, tilting its head forward or throwing it back, turning it to the right and left, stretching or gathering its feet, fetal facial movements, namely the smile of the baby in the womb, opening and closing his eyes, sticking out his tongue, chewing, yawning, grimacing. It is possible to closely monitor with four-dimensional ultrasonography.
If there is an anomaly detected in the baby, it is examined in more detail with three- and four-dimensional ultrasonography. In some cases, for example, depending on the baby's position or if the water is low, a good image may not be taken. It is thought that the ability of each family member to see the four-dimensional ultrasound images of the baby, to follow its movements, and to see and imagine what it looks like, increases the bond between the parent and the baby. As can be expected, these moments are quite exciting for families. The baby's three- and four-dimensional ultrasound images can be stored digitally and families can watch it on their own video or computer.
