What Is Ultrasound, How Does It Work, What Are The Types?

What is ultrasound?

Original name ultrasonography This device examines the changes and developments in our body that we cannot see with our eyes. The working principle of ultrasound is based on using sound waves that cannot be heard by the human ear and by allowing them to move between tissues. The image obtained while the ultrasound device is working is real-time, it can be viewed with a monitor.

The ultrasound device consists of 2 parts. One is the probe that is in contact with the skin, the other is the central processing unit that converts sound waves into images.

Why is an ultrasound done?

It is not possible to fully understand what the problem is without seeing the problems, changes and developments taking place in our body. With the ultrasound invented to eliminate this situation, problems especially in the abdomen and breast area can be easily detected. Most of the ultrasound is:

It is used to monitor baby development during pregnancy, to detect problems in internal organs, to observe problems in soft tissues.First, let’s answer the questions such as “ Can you drink water before ultrasound? “, “ Open ultrasound? “. This issue depends on the reason for the ultrasound procedure. Your doctor will tell you what to do.

Before starting the shoot, your doctor uses a transparent ultrasound gel to provide a better view of the internal organs and to provide lubrication between the device and the skin. This gel does not have any harm and is easily cleared from the body as it is water-based.

After this process, the probe is moved around the area that needs to be monitored. Your doctor may sometimes press the device to get a better view. This move has no harm. After the process is finished, a printout is taken from the device. From here, the image is interpreted and processed into the report.

Is ultrasound harmful?

Especially expectant mothers have reservations about this issue. They wonder the answer to the question “ Does ultrasound harm the baby? “. Contrary to popular belief, ultrasound does not contain radiation. Therefore, it does not harm neither the baby nor the expectant mothers.

What are the ultrasound types?

2-dimensional (obsetric ) ultrasound

This is the standard ultrasound type.

Since very efficient images cannot be obtained in the first months, experts recommend starting from the 16th week. In the first months, it is usually applied to see the baby’s sac and hear the heartbeat. The development of the baby can also be monitored in the future. Gender determination can also be done thanks to 2D ultrasound.

Detailed (detailed) ultrasound

Detailed ultrasound is often available for pregnant women. is a method used. More information about the baby’s organs and health status can be obtained with this type of ultrasound.

The purpose of a detailed ultrasound is usually to determine whether the baby has any abnormalities. In this way, most congenital problems can be detected, but alone is not enough. If your doctor detects such a problem, he / she will immediately direct you for other examinations.

What is looked at in a detailed ultrasound? ” Let’s say it one by one.

The brain, skull development, spine, heart, stomach, kidney, baby’s placenta, intestines, thoracic organs are thoroughly examined in detailed ultrasound.For this process, usually 19.-23. weeks are preferred. Because during this period, the amniotic fluid is denser and a clearer image can be obtained.

3/4 dimensional ultrasound

These ultrasound types are completely optional. It does not detect serious anomalies that develop in the baby, but may reveal surface problems such as cleft palate. The purpose of 3 or 4 dimensional ultrasound is to examine the baby’s movements, hands and arms. These ultrasounds are performed at regular intervals with the guidance of the doctor, and the family can see their baby. In this system, which provides a much clearer image than 2-dimensional ultrasound, it is even possible to see the baby’s smile.

Also, it is much easier to determine the gender of your baby thanks to this ultrasound type! But as we said, 4-dimensional ultrasound is not a necessity, it can be done as long as you request. Let’s just say it may be a bit more expensive than other types of ultrasound.

Color ultrasound

The purpose of this type of examination, whose real name is color doppler ultrasound, is not to see the baby in color and detail; to examine blood flow velocity and placental status.

These colors are formed in the computer environment. As the blood flow approaches and moves away from the probe, red and blue colors are seen, and the status of the flow is detected.

Color Doppler ultrasound is usually used for expectant mothers who have a risky pregnancy. Your doctor will direct you to have this type of ultrasound done if you need it.

Vaginal (transvaginal) ultrasound

This method, popularly known as “ bottom ultrasound “, provides more detailed information about the baby in the first months of pregnancy and uterine fibroids in the womb. Used to detect if there is any problem such as. This method is preferred because clear information cannot be obtained with abdominal ultrasound during these months.

Transvaginal ultrasound does not cause a problem such as miscarriage or bleeding, it is very harmless. Because there is no effect on the uterus during the ultrasound. The environment he examines is only the cervix and its environment.
