Can I still do four dimensional deformity at 26 weeks of pregnancy?

It is also possible to do four-dimensional deformity, but the best time should be 16 to 20 weeks, and it is better to perform large deformity at this time.

Generally, four-dimensional screening has a fixed time period, and if the month is small, the baby's development is not complete, so it is difficult to see the baby's indicators, so it can generally be postponed but not in advance.

It is best to do it around 24 weeks of pregnancy, and do not do it more than 28 weeks at the latest, and you can still do four-dimensional deformity at 26 weeks.

No. Because the four-dimensional deformity is done at 20-24 weeks. If the gestational age is too large, the results will be inaccurate.

Pregnant women do four-dimensional deformity at 20 to 24 weeks, because at this time, the baby's organs are fully developed, and the amniotic fluid volume is also more suitable for four-dimensional deformity. Some hospitals can still do it up to 26 weeks, but if you have time, try to do it in advance.

OK. However, it is best to choose about 20 weeks to 24 weeks of pregnancy, during which the four-dimensional color ultrasound examination is done, the fetal development is suitable, the amniotic fluid is large, and the fetal mobility is good, so ultrasound can detect most of the fetal development malformations.

Generally speaking, you can do four-dimensional deformity at 26 weeks of pregnancy, and you can do four-dimensional deformity at 23 or 26 weeks under normal circumstances.

The best time for four-dimensional deformity examination is between 20-24 weeks of pregnancy, and ultrasound is an ultrasound examination that must be performed during pregnancy, and women should undergo relevant examinations according to the doctor's instructions.

The examination of large deformities should be done between 20 and 24 weeks of the fetus, preferably no more than 28 weeks, and the whole body structure of the fetus should be systematically examined by B-ultrasound to rule out prenatal malformations. Generally, at 20-24 weeks of pregnancy, the fetus has developed completely, and the space in the uterine cavity is relatively large, at this time, if the ultrasound examination is performed, the observation of the fetus is clearer, and if the fetus is abnormal, it is better to deal with it in this week. Usually at 20-24 weeks of pregnancy, a large deformity ultrasound examination is arranged to determine whether the fetus has congenital diseases, such as anencephaly, severe heart diseases, etc.

Patients do not need to have an empty stomach and hold urine, and they can eat and drink some water half an hour before doing the deformity ultrasound, which can increase fetal movement. Before going for the examination, it is best for the expectant mother to wear separate clothes from the upper and lower clothes, so that it is convenient for the examination, and it is necessary to relax appropriately and relieve tension.

The first examination should be done at 3-4 months of pregnancy, and the gestational age should be 11-14 weeks.

During this period, the baby's development and activity status can be observed as a whole, potential chromosomal indicators such as fetal NT value can be screened, and some serious fetal structural malformations can be diagnosed.

The second examination should be done at 4-5 months of pregnancy, and the gestational week should be 17-20 weeks.

During this period, the hands and feet of the intrauterine fetal version have been preliminarily formed, and the extension and development of the fetal hands and feet can be observed, and the fetal hand and foot malformations can be more clearly diagnosed.

The third examination, the best time for deformity, 5-6 months of pregnancy is appropriate, and the gestational week is 20-26 weeks.

This period is very important for the baby, the four-dimensional color ultrasound system can completely detect the baby's development, screening and diagnosis of fetal structural malformations, hereditary diseases, etc., which is the best period for deformity.

Pregnant mothers are extra attentive and worried about the baby in their womb, especially during the prenatal check-up. Nowadays, in addition to black rulers and white color ultrasound, there is also a four-dimensional color ultrasound, and many pregnant mothers will choose to do four-dimensional color ultrasound, so that they can see the fetus more clearly.

After a woman becomes pregnant, the general pregnancy period reaches 24-28 weeks, and the various organs of the fetus gradually develop and mature. 22 weeks can also do four-dimensional color ultrasound, but it is a bit early, and the results are not very accurate. The doctor will also decide whether Lingshou is suitable for four-dimensional color ultrasound according to the pregnant woman's own condition, and you can listen to the doctor's opinion.

Four-dimensional color ultrasound is mainly used to check the growth and development of the fetus, and the results are relatively accurate. It can know in advance whether the fetus has congenital diseases, such as congenital heart disease or congenital malformations, so that parents can prepare psychologically in advance. Therefore, for pregnant mothers, four-dimensional color ultrasound is very necessary.

The ** of four-dimensional color ultrasound is generally about 300 yuan-400 yuan, and the ** of four-dimensional color ultrasound will be different in different regions and hospitals. In addition, the technology of four-dimensional color ultrasound is relatively advanced, so it is recommended that pregnant mothers should choose a formal institution for examination if they want to do four-dimensional color ultrasound, so as to avoid unnecessary things.

Large discharge anomalies are performed at 24-28 weeks of gestation, and fetal anomalies are ruled out by a high-resolution color Doppler flow imaging machine.

Conventional items: fetal position, double parietal diameter, occipital frontal diameter, abdominal diameter, femoral length, axle length, amniotic fluid, fetal movement, fetal heartbeat, fetal heart rate, placental position, placental thickness, placental grade, lower edge of placenta.

Nine screenings for large row deformities: cerebellum, upper lip, gastric vesicles, four chambers of the heart, both kidneys, bladder, tibia, fibula, ulna, radius, spine, abdominal wall.

At present, most of the hospitals are three-dimensional and four-dimensional color ultrasound. It is not necessary to use four-dimensional color ultrasound for large-scale deformity examination, but three-dimensional color ultrasound and two-dimensional color ultrasound can also be detected.

However, at present, four-dimensional color ultrasound is the most advanced color ultrasound equipment in the world. "4D" is an abbreviation for "Four Dimensions". The fourth dimension refers to the vector of time, so it is also called real-time three-dimensional.

It provides multi-faceted applications in a wide range of fields, including abdominal, vascular, small organ, obstetric, **, urology, neonatal and pediatric. It can intuitively and three-dimensionally display the real-time dynamic image of the fetus and understand the fetal movement process in the uterus. Dynamic recording of the fetus's intrauterine status can also be kept as a permanent memorial.

Therefore, most pregnant mothers will choose four-dimensional color ultrasound during the major deformity examination.

Can you do four-dimensional color ultrasound at 26 weeks pregnant?Regarding this problem, relevant people said that under normal circumstances, no matter when a woman has a four-dimensional color ultrasound examination, she needs to discuss with the doctor according to the situation, and wait for the doctor to confirm that the four-dimensional color ultrasound examination should be carried out, and it cannot be carried out at will.

Can you do four-dimensional color ultrasound at 26 weeks of pregnancy 24-28 weeks of pregnancy is the best time to take four-dimensional color ultrasound, because the fetus is about 24 weeks is the period of rapid development of the brain, the fetal structure has been formed during this period, the size of the fetus and the amniotic fluid are moderate, the activity space in the uterus is larger, the fetal bone echo is less affected, and the image is relatively clear.

The best time to do 4D color ultrasound varies from person to person, and the results obtained from different needs of 4D color ultrasound will be different. Generally speaking, pregnancy can be divided into three stages: pre-pregnancy (January-March), second pregnancy (March-June), and third trimester (June-September).

1. In order to shoot the whole body of the fetus: at this time, you can choose to do four-dimensional color ultrasound in the first trimester, the fetus is still small when the orange is sold, and the whole body can be illuminated through the instrument, but it is not recommended to do four-dimensional color ultrasound in the first trimester, so as not to have adverse effects on the fetus.

2. In order to check the external defects of the fetus: at this time, you can choose to do four-dimensional color ultrasound in the second or third trimester of pregnancy, at this time the fetal body has developed to a certain extent, and it is impossible to take care of the whole body, but you can observe the shape of a certain part of the fetus.

What is four-dimensional color ultrasound Four-dimensional color ultrasound is a kind of ultrasound examination, in addition to the function of general color ultrasound, it can also carry out three-dimensional imaging of the fetal head and face, which can clearly display the eyes, nose, mouth, jaw and other states, and can assist doctors to directly diagnose fetal congenital malformations, including surface malformations, visceral malformations and head and face malformations, and can determine the precise position of the fetus in the uterus. In addition, the four-dimensional color ultrasound of the confession group also adds time dimension parameters on the basis of these functions, which can observe the dynamic living image of the fetus in real time.

Generally speaking, four-dimensional color ultrasound can see large fetal malformations, such as neonatal congenital heart disease, cleft lip and palate, edema fetus, polydactyly (toe) and external ear malformations. However, four-dimensional color ultrasound is not a panacea, for example, neonatal deafness, cataracts, etc. cannot be detected.

Pregnant women should understand the importance of four-dimensional color ultrasound screening and perform four-dimensional color ultrasound examination according to the time prescribed by the doctor.
