Original title: How long is the pregnancy for B-ultrasound? The role of b-ultrasound in pregnancy

How long does it take to do a b-ultrasound after pregnancy? As we all know, a b-ultrasound is an indispensable pregnancy test. Some expectant mothers want to get a quicker General imaging of fetal development and will do a b-ultrasound. This is incorrect. The time of b-ultrasound during pregnancy is very delicate, let's find out.

How long is pregnant for B-ultrasound

Because if you do too much B-ultrasound within 2 months of pregnancy, embryonic cell division and human brain formation may be affected. Excessive b-ultrasound will affect fetal development, because fetal organ development is not perfect at 4, 5, and 6 months of pregnancy. of course there are exceptions. The time of B-ultrasound examination is generally best after 5-6 months of pregnancy. The older the baby's gestational age, the smaller the impact of ultrasound on the fetus. It is generally believed that the fetus within 18 weeks of pregnancy is best not to do b-ultrasound, especially in the early stages of pregnancy. Of course, except for special circumstances such as vaginal bleeding, a B-ultrasound examination is required to determine whether the fetus is alive, whether the pregnancy continues, whether there is an abnormal pregnancy or mole.

In addition, what is the role of b-ultrasound during pregnancy?

The role of B-ultrasound during pregnancy

B-ultrasound diagnosis is an ideal examination method in the field of obstetrics. In the first half of pregnancy, b-ultrasound can diagnose fetal malformations such as pregnancy, stillbirth, mole, ectopic pregnancy, pregnancy with tumors, uterine malformations, hydrocephalus, and anencephaly. In the second half of pregnancy, the use of b-ultrasound can diagnose fetal position, twins or multiple pregnancies, excessive or oligohydramnios, fetal malformations, fetal gender, and placental location to determine the cause of bleeding in late pregnancy, fetal head diameter measurement, fetal intrauterine situation, and prediction Fetal maturity-judging fetal maturity and predicting gestational age through placental grading, amniotic fluid volume, fetal biparietal diameter, etc.

Amniotic fluid volume is very important for the growth and development of the fetus. Too much or too little amniotic fluid may indicate abnormal fetal development. Therefore, the b-ultrasound examination is very important to guarantee prenatal and postnatal care. Observe the physiological activities of the fetus: b-ultrasound can directly observe the activities of the fetus in the mother's body, such as breathing, fetal movement, body movement, limb movement, etc.

After the 13th week of pregnancy, B-ultrasound can clearly show the fetus’s head, trunk, heart, lungs, liver, spleen, stomach, kidney, bladder and other organs and limbs and bones. Through the measured data, it is estimated that the fetus The development status can also determine the fetal position and placental position, evaluate the placental function, and choose the delivery method.

It is necessary to have an accurate time for the b-ultrasound examination during pregnancy. Don't do too much.
