How to check fetal weight by color Doppler ultrasound

After becoming pregnant, women need to have regular prenatal checkups. Through prenatal checkups, they can understand the development of the fetus in a timely manner, and at the same time, they can also find some existing problems in a timely manner. There are many items in prenatal checkups, such as color Doppler ultrasound, etc. Some pregnant women will use color Doppler ultrasound to understand the weight of the fetus. If the weight is found to be too low, the fetus will be supplemented with nutrition. So how does color Doppler ultrasound check the weight of the fetus?

First, how to determine the fetal weight using color Doppler ultrasound? Fetal weight (EFBW) = 1.07*BPD*BPD*BPD+0.3*AC*AC*FL BPD. The units of biparietal diameter, AC, abdominal circumference and FL femur length are all centimeters, and the calculated weight is in grams. : : : : : : : : : : : : : : : The purpose of predicting fetal weight is to detect problems in fetal development as early as possible. Generally speaking, there will be a plus or minus 10-15% error between the actual birth weight and the predicted weight. For example, if the birth weight is 4000 grams, the error range will be 400 grams. In other words, the heavier the baby, the greater the margin of error.

Second, color ultrasound. There are many types of color ultrasound, including ordinary color ultrasound, three-dimensional color ultrasound, and four-dimensional color ultrasound. Color Doppler ultrasound is based on B-ultrasound. The main advantage of color Doppler ultrasound is that it can clearly understand the detailed situation of the fetus in the mother's womb.

How to check the fetal weight by color ultrasound? The above content introduces the ultrasound used by color ultrasound. Ultrasound is a physical mechanical wave, not radiation. The intensity of medical ultrasound is very low, and normal examinations will not affect pregnant women and your fetus at all. Color Doppler ultrasound can show the blood flow and development of the fetus. Color ultrasound only scans the human body for a short time and has no adverse effects on pregnant women and fetuses.
