Abbreviation for four-dimensional color Doppler ultrasound? 4D? That is, four-dimensional imaging technology is based on three-dimensional ultrasound images, plus time dimension parameters. Simply put, pregnant mothers can intuitively see what their babies are doing in their stomachs.

Doctors can also diagnose fetal congenital malformations, such as surface malformations, visceral malformations and head and face malformations.

You can check the baby's deformity and poor development at an early stage, so as to take timely measures to reduce birth defects.

Let's take a look at 5D (five-dimensional) color Doppler ultrasound.

5-D color Doppler ultrasound, which sounds mysterious, is actually 5-D color Doppler ultrasound. It is based on 4-D ultrasound images and spatial dimension parameters to obtain a more stereoscopic and realistic 5-D image.

Compared with four-dimensional color Doppler ultrasound, 5-D color Doppler ultrasound can observe the growth and development of intrauterine fetus in many directions and angles. At the same time of examination, prospective fathers can see the baby in their stomachs just like watching a movie.

In fact, four-dimensional and five-dimensional can vividly show the baby's dynamics. Compared with the previous four-dimensional, the price of natural 5D is definitely slightly higher. As for how much it is higher, it varies according to the city and hospital where the pregnant mother is located.

Tips: As one of the scientific basis for screening fetal diseases, 5D color ultrasound can not provide an absolute diagnosis for fetal diseases.

03 How much do you know about pregnancy with large ovulation and small ovulation?

What is big platoon deformity?

Examination time: 22-24 weeks of pregnancy.

The measurement by B-ultrasound is similar to the general B-ultrasound examination. The pregnant mother has no discomfort and does not need to hold her urine before the examination.

How long will it take to complete the examination: Generally, it will be completed within half an hour, depending on whether the baby cooperates.

Purpose of examination: Through three-dimensional or four-dimensional color Doppler ultrasound, of course, now there is the so-called five-dimensional color Doppler ultrasound technology, which can reflect the development of fetal face and organs through imaging, and can be used to detect and screen fetal malformations, providing accurate scientific basis for early diagnosis of fetal congenital body surface malformations and congenital complex malformations, including screening fetal head, face, spine, heart and other organs.

What is small row deformity?

Examination time: 28-32 weeks of pregnancy is also measured by B-ultrasound.

How long does it take to complete the examination? Generally, it will be completed within half an hour. If the baby cooperates well, it will be completed in about 10 minute.

Purpose of examination: The purpose of examination for small-row malformation is the same as that for large-row malformation. The time of large-scale teratology examination is 20-24 weeks. At this time, there are some subtle changes in the fetus that have not yet been shown. It is a supplement to the large-scale teratogenesis to wait for the fetus to develop for a few weeks, and there is only a time difference between the two.

Preparation before troubleshooting inspection

Some mothers are always very nervous before they go for an abnormality check, because there are indeed pregnant mothers who have failed many times, mainly because the baby does not turn over, always lying down or covering his face with a small hand, and does not cooperate with the check.

Therefore, the doctor can't take the best angle of examination at all, and can't see the baby's face, eyes, nose, mouth, arms, fingers, legs and toes, so he can't check the deformity. I believe this is a situation that doctors and pregnant mothers do not want to see during the abnormality examination.

Get ready for the trouble and get through customs smoothly!

①? Sweet? Give me a little head.

Mothers who have done four-dimensional examination know that the general four-dimensional examination is about in the morning, but some babies are not active in the morning. At this time, mothers can give some to their babies? Sweet? Head, such as eating a chocolate, eating a biscuit, etc.

Eating sweets properly can not only relax the mother's mood, but also make the unborn baby active. Sweet? The head awakens the sleeping baby.

Tips: Pregnant mothers with gestational diabetes should eat sweets carefully.

② Select the baby's active period for examination.

There are certain rules when the baby is active, but there are also individual differences. Generally speaking, babies are more active at around 0: 00 am 10 o'clock, just after eating at noon, and around 4: 00 pm.

Combined with the expert time and the appointment time, pregnant mothers can have a four-dimensional color ultrasound examination at 9- 10 in the morning. I believe most babies will cooperate.

③ The examination process is suspended, and the pregnant mother can chat with the baby.

Fetal TAs have hearing, so this is also the origin of prenatal education. If the baby is sleeping or in a bad mood during the abnormality check-up, the doctor will ask the mother to go out and have a rest before doing the check-up.

Mom may wish to chat with TA, wake up the sleeping baby, and cheer herself and her baby up.

④ Climb stairs properly.

Experienced mothers all know that sometimes they can't pass an abnormality check, and the doctor will let the pregnant mother go out to climb the stairs or take a walk, so as to increase the amount of exercise and make the baby active quickly.

Tips: It is ok to climb the stairs, but pay attention to safety. It is best to let the prospective father accompany you.

What if the big row is abnormal?

There are many times of ovulation during pregnancy, including 1 1 week+~13 weeks of NT examination, Down's screening, 22-24 weeks of large ovulation and 28-32 weeks of small ovulation. If the large ovulation examination fails, the general doctor will inform the pregnant mother of the risks, whether to terminate the pregnancy or continue further investigation, and the pregnant mother and her family will work together.

Tips for 05 large row abnormality inspection

There is no need for an empty stomach, so pregnant mothers can go to the hospital for examination after eating, so that the fetus is more active and conducive to examination.

② Go to the hospital at least ten minutes in advance, sit quietly for a while first, talk with the baby in the belly and then have an examination, so as to wake up the sleeping baby and ensure that the examination can be completed at one time and avoid the examination? Stop halfway? The situation appeared.

(3) Remember to wear clothes that are separated up and down on the day of inspection, and never wear jumpsuits, bibs and other clothes.

4 There is no need to urinate. There is a mother around who thinks that she wants to urinate, and she didn't say hello to the doctor in advance. She has been urinating to the hospital since she got up in the morning. Before the examination, the doctor told her not to urinate. Isn't this a crime of being wronged?

⑤ It's best to be accompanied by family members, so that pregnant mothers don't have to run in person to help with bags and go upstairs and downstairs to check out.
