When is the best time to do gynecological B-ultrasound?

Pregnant women belong to a relatively special group of people. There are many issues that need to be paid attention to at this time. If you are not careful, some problems will arise. If the fetus is deformed, it will be very troublesome. To determine whether the fetus is healthy, we need to use B-ultrasound examination to judge. However, there are certain time restrictions for B-ultrasound, so we have to choose the best time. So when is the best time to do a gynecological B-ultrasound?

The best time to take a four-dimensional color ultrasound is between 24 and 28 weeks of pregnancy, because the fetus's brain is developing rapidly around 24 weeks. The fetal structure has been formed at this time, the fetus is of moderate size and amniotic fluid, there is more space for movement in the uterus, the fetal bone echo is less affected, and the image is clearer.

The best time to do four-dimensional color ultrasound varies from person to person, and the results will be different depending on the needs of the four-dimensional color ultrasound. Generally speaking, pregnancy can be divided into three stages: early pregnancy (January-March), mid-pregnancy (March-June), and late pregnancy (June-September). The four-dimensional color ultrasound results taken in these three periods are also different. Due to individual differences among pregnant women, please contact your doctor for the specific time and set the time according to the doctor's instructions.

1. To take a full-body picture of the fetus: You can choose to do a four-dimensional color ultrasound in the early stages of pregnancy. At this time, the fetus is still small and the whole body can be photographed through the instrument, but it is not recommended to do a four-dimensional color ultrasound in the early stages of pregnancy to avoid adverse effects on the fetus.

2. To check for external defects of the fetus: At this time, you can choose to do a four-dimensional color ultrasound in the second or third trimester. At this time, the fetus's body has developed to a certain extent, and it is impossible to take a whole-body picture, but you can observe the morphology of a certain part of the fetus.

The above is an introduction to the best time to do a gynecological B-ultrasound. Regular B-ultrasound examination can allow us to clearly grasp the health of the fetus. However, the B-ultrasound should not be done too early. You can do it in the middle of pregnancy. This will allow you to see more clearly and judge the development of the fetus more accurately.
