How to check the fetal weight from the ultrasound report?

During the entire process of pregnancy, mothers are very sure whether the fetus is normal. In order to understand the condition of the fetus in time, the most important method is to go to the hospital for a pregnancy check-up. B-ultrasound is an important way to understand the condition of the fetus. Every time you go to the hospital for a B-ultrasound, there will be many results on the B-ultrasound report, such as the B-ultrasound week number. The B-ultrasound week number is calculated based on the size of the fetus. So how do you know the weight of the fetus through the B-ultrasound report?

How to check the fetal weight from the ultrasound report?

The weight of the fetus is an important basis for assessing the growth of the fetus. In the late pregnancy, the doctor will arrange for the expectant mother to undergo an ultrasound examination to assess the weight of the fetus, whether it is suitable for natural delivery, etc. But the fetus is still in the mother's belly. How does the doctor calculate the fetal weight based on the data from the B-ultrasound report? How to calculate the fetal weight based on the ultrasound report?

How to calculate the fetal weight based on the B-ultrasound report

Since there is a large error in measuring the length of the fetus, for example, the curled posture of the fetus and the size of the skeleton may cause misjudgment of the results. Therefore, in medicine, weight rather than height is used as the basis for assessing fetal growth.

Measurement formula collection:

1. Fetal weight (g) = 1.07 × BPD × BPD × BPD + 0.3 × AC × AC × FL (unit: cm)

2. Fetal weight (g) = 260.69 × HC-4973.72 (unit: cm)

3. Fetal weight (g) = 171.48 × AC-2686.60 (unit: cm)

4. Fetal weight (g) = 747.42 × FL-2232.56 (unit: cm)

Kind tips:

These are several formulas that can be used to calculate fetal weight using B-ultrasound data. However, due to the individual differences between each expectant mother, there will definitely be certain errors in the fetal weight calculated using B-ultrasound data. Expectant mothers can only use this as a reference. It is best to consult a doctor about the development of the fetus.

B-ultrasound data to see the gender

1. Check the B-ultrasound test for gender in early pregnancy

1. Look at the B-ultrasound data: If the length and width of the gestational sac differ by more than twice, the baby is likely to be a boy. The length and width of the gestational sac are equal, so it is likely to be a girl.

2. Look at the shape of the gestational sac: if it is eggplant-shaped or long, it is likely to be a boy; if it is round, it is likely to be a girl.

It is said that the size and shape of the gestational sac can be used to determine the gender of the fetus by looking at the ultrasound report of 40-50 days of pregnancy. If the gestational sac is oval or round, it is a girl, and if it is elongated, it is a boy.

2. Check the B-ultrasound test for gender in late pregnancy

According to folk saying: the biparietal diameter is the transverse diameter of the fetus's head, and the femur length is the length of the fetus's thigh bone. The older generation says that a boy has a longer head and shorter thighs, that is, biparietal diameter - femur length > 2, and a girl has a smaller difference between her head and legs.
