Can I do 4D scan when I am eight months pregnant?

Women need to do a four-dimensional color ultrasound during pregnancy. Compared with the color ultrasound we usually do, the four-dimensional color ultrasound will look clearer and can clearly see the appearance of the fetus and the development of the limbs. Generally, the four-dimensional color ultrasound is done when the woman is five or six months pregnant, because during this period the fetus can already fully develop its limbs. So, can the four-dimensional color ultrasound be done when the woman is eight months pregnant?

Can I still do 4D color Doppler ultrasound when I am eight months pregnant?

Experts say that when a woman is eight months pregnant, it is generally not appropriate for her to undergo a four-dimensional color ultrasound examination to exclude fetal abnormalities. However, she can do a four-dimensional color ultrasound to take intrauterine photos at this time. This is mainly because the best time for four-dimensional color ultrasound examination is 20-28 weeks. Because during this period the fetus's limbs and major organs have all developed, and the amniotic fluid is more suitable for fetal malformation screening. However, 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.

For mothers who are eight months pregnant, the effect of four-dimensional color ultrasound fetal abnormality screening is not very good. The main reason is that after doing the four-dimensional color ultrasound fetal fetal abnormality screening at this time, friends cannot do a better job of post-examination treatment, and the bone interference is relatively large at this time, and the fetal fetal abnormality screening effect is not very good. Therefore, friends are not advised to do fetal fetal abnormality screening at this time. However, if friends do four-dimensional color ultrasound and take intrauterine photos at this time, it is still a good idea.

When is the best time to do 4D color Doppler 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 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. However, it is inappropriate 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.
