Why is there no four-dimensional color Doppler ultrasound in big hospitals?

Many pregnant mothers around me will have a four-dimensional examination when the fetus is around 23 weeks old. The doctor in a local county hospital also told us that the next pregnancy test should have a four-dimensional examination.

It is easy to mislead inexperienced pregnant mothers at this time. Inexperienced pregnant mothers may mistakenly think that this examination item is four-dimensional. In fact, the prenatal examination items on pomelo, pro-baby, baby tree and other apps are all written as basic examination+large ovulation examination. At this time, inexperienced pregnant mothers are still easily misled and will think that doing four dimensions is ovulation. In fact, four-dimensional and large ovulation period are two different contents. If we make an analogy, they will be misled.

Then what is four-dimensional and what is big row deformity?

Four-dimensional ultrasound is actually a kind of B-ultrasound, the full name is four-dimensional ultrasound or four-dimensional color ultrasound. B-ultrasound includes two-dimensional ultrasound, three-dimensional ultrasound and four-dimensional ultrasound.

What's the difference between these three types of B-ultrasound?

Two-dimensional B-ultrasound, the displayed image is a plane image just like our sketch painting. Three-dimensional B-ultrasound, the displayed image is like three-dimensional graphics in CAD software, which is a three-dimensional image. Four-dimensional B-ultrasound, the displayed image is based on three dimensions, and the three-dimensional imaging in a period of time is processed into the form of video through software processing.

Three-dimensional and four-dimensional, in fact, are on the basis of two-dimensional, through program calculation to make the effect.

Large-scale abnormal examination based on B-ultrasound: Large-scale abnormal examination examines fetal development abnormalities, such as brain abnormalities, limb deformities, fetal edema, etc. Pass the b-ultrasound. This inspection is usually completed within 20-24 weeks. After the second trimester, the baby's main organs have been formed and can be clearly displayed in B-ultrasound.

Tip: Hunger caused by fasting will affect the test results. Eat properly before the examination to ensure blood sugar supply. And exercise properly, so that the intrauterine fetus can exercise properly and ensure a fetal position that is conducive to inspection.

So how many dimensional B-ultrasound should be chosen for large row deformity?

In fact, three-dimensional and four-dimensional can be used. General public hospitals use two or three dimensions, and private hospitals use four dimensions. The purpose of using Siwei in private hospitals is because Siwei can attract many pregnant mothers who don't know B-ultrasound to check with them.

that this is not the important question.

The point is to give you a big troubleshooting doctor, his technical level. It can even be said that the most important thing for large-scale exclusion is to have a doctor with good skills to do B-ultrasound examination for himself.

Why do you say that?

The most easily obtained and easily distinguished evidence is that a doctor with average or even poor skills will have relatively more "vague" expressions similar to "so-and-so" in the ultrasonic findings of his B-ultrasound diagnosis report.

This unclear display may be because the doctor's skill in doing B-ultrasound for pregnant mothers is not good enough, or it may be that the doctor found that the fetus did not move much, and later the examination did not let pregnant mothers eat or exercise, but just made do.

In other words, the reliability of this examination is 80%, but the reliability of this examination done by the doctor himself has become 50%.

You know, there is a disclaimer at the bottom of the diagnosis report, and it even indicates that the diagnosis result cannot be used as a legal basis. In other words, you can't blame me for the unreliable diagnosis report, and you can't give me any trouble.

Fetal malformation can be divided into chromosome malformation and B-ultrasound malformation. Chromosome abnormality check, now use Down's screening.

Chromosome abnormalities, also known as Down's screening, are performed at about 15-20 weeks. There are still some high-risk pregnant mothers in Tang sieve, not a few. However, there is a high risk in Tang screening results, so pregnant mothers don't have to worry too much. Through further non-invasive DNA or amniocentesis, it will generally become low risk. The high risk of Tang Screen only reminds us that the possibility of chromosome abnormality is very high, and it is not a definite diagnosis.

My partner and I always thought that four-dimensional color Doppler ultrasound was a large-scale abnormal examination. I went to the provincial hospital to make an appointment for four-dimensional color Doppler ultrasound. The doctor said not to do four-dimensional, and then I opened obstetric ultrasound, cardiac ultrasound and massive blood tests.

Then we were cheated, and I don't know what happened. I thought, how can such a big hospital not have four-dimensional color Doppler ultrasound? Not logical, is it? The doctor only said that our hospital doesn't do four-dimensional, and didn't say anything else, giving people the impression that I am very busy and don't want to explain anything to you. You'd better stop asking, or I'll be angry.

Personally, I think most doctors in big public hospitals are like this because there is no shortage of patients at all. On the contrary, doctors in private hospitals have a particularly good attitude, but private hospitals are likely to charge high fees and may make you do a lot of tests.

For example, we did a big troubleshooting in the provincial hospital, and the cost was 346 yuan, but it was 495 yuan to go to the county-level maternal and child hospital in the next city. Moreover, during the treatment, the doctor pointed out a piece of red paper and said that these tests can be done, and you have to pay another 200 yuan.

We don't know what we are checking, and we can't understand the instructions on the list. Although this kind of hospital is public, its purpose is obvious, which is to make you pay as much as possible, instead of treating people like provincial hospitals. Moreover, this county-level maternal and child hospital will write in the B-ultrasound diagnosis report of pregnant mothers: It is recommended to review the fetal heart rate for free after half a month. Then the doctor will tell you the next pregnancy test: glucose tolerance (oral glucose tolerance test).

Obviously, the hospital uses the so-called free reexamination to attract pregnant mothers to their hospital for the next examination. Moreover, it is even more outrageous to spread outside, saying that this hospital can do fetal heart ultrasound for free by doing four dimensions. Lying in the trough, how many outsiders have been cheated by this strategy to check.

Because we hadn't paid for the checklist prescribed by the doctors in the provincial hospital at that time, because we didn't know what the doctors prescribed, we called two other big hospitals nearby to ask, and the reply was that we didn't do four dimensions, and it was not the same thing for the doctors to reply to four dimensions. Now we are more mysterious.

In the end, I didn't do anything, drove 100 km and went home again. Because people around me say that a county hospital in the next city is doing four-dimensional, and some people around me are doing it there. Then I went the next day.

After returning to China, Baidu began to search for the difference between large row deformity and four-dimensional color Doppler ultrasound. Baidu's still disappointing garbage is unreliable, and the search results have everything. I don't know who to listen to. So, don't use Baidu search if you have any questions. Now I usually use Tik Tok to search, and finally I use Watermelon Video app, which feels that the search results of Watermelon Video are more professional.

Until now, I probably know a little bit about pregnancy test. As Mr Wang Dongyue said, everyone should know some medical knowledge. It really is. ? I write these contents in the hope that pregnant mothers will walk less in the ten-month pregnancy test.

I wish pregnant mothers a successful pregnancy test!
