Ultrasound Ultrasound, Your Guide to Every Pregnancy Scan

How does ultrasound work?
The ultrasound is carried out with an ultrasound transducer (a probe; or a producer of ultrasound waves). Ultrasound ultrasound is usually done using a probe or the same transducer. First, they slip the abdominal surface with a laxative gel (in abdominal ultrasonography) and then move a small device onto the abdomen to display a fetus on the screen. The basics of ultrasound are sound waves. The image of the embryo is the result of sending and returning sound waves.

"If you notice a particular issue or concern during pregnancy, you can do extra ultrasounds and make sure that you have the right balance," said Dean Meridith, an ultrasound technician at Portland Hospital in London.

If you have gestational diabetes, pregnancy difficulty or other complications, you will probably need more ultrasounds. Multiple pregnancies, any fetal abnormality or abnormal position of the fetus can be detected in ultrasound.



Primary ultrasound
If you have a history of abortion, if you have bleeding or severe pain, your first pregnancy ultrasound will be between 6th and 11th weeks. Your doctor may use a vaginal scan probe that may not be able to diagnose your fetus as the usual equipment.

Sonography of the twelfth week
The twelfth week is when you left the third month. You will probably have a pelvic ultrasound, where the transducer is placed on the skin on the pelvis.

NT ultrasound (transparent space behind the neck)
This ultrasound is performed between 10 and 13 weeks, this ultrasound examines the risk of Down syndrome in your baby. In this ultrasound, the size of the head to the end of the embryo's spine and then the amount of fluid behind the neck is measured. Here, the skin appears as a white line and the black subcutaneous fluid.

Anomaly ultrasound
For most pregnant women, this ultrasound is performed between weeks 19 and 20, this is an accurate ultrasound that determines whether your baby is normal or has a problem or anomaly.


After 20 weeks
If you have a history of birth defects, such as heart problems in your family or other problems, it may seem necessary to consult your doctor at this time for an additional sonography.

Advantages of 3D and four-dimensional ultrasound
3D and four-dimensional ultrasound show a more complete and brighter detail of the fetal body than a two-dimensional ultrasound. In these ultrasounds, we can more accurately detect large anomalies.

This type of ultrasound is performed from the fifteenth to the twenty sixth week and is considered a better way to examine the condition of the fetus. In such saunas, the mother can also see the responses and movements of her child more clearly.

اگر عقاید خود را با تفکر و مطالعه به‌دست آورید، کسی نمی‌تواند به آنها توهین کند. اگر کسی چیزی بر خلافشان بگوید عصبانی نمی‌شوید، یا میخندید یا به فکر فرو می‌روید.

If you get your ideas by thinking and study, nobody can insult them. If someone tells you the opposite, you will not get angry, either you laugh or think about it.
