How does color Doppler ultrasound say pregnancy?

summary

My friend has been pregnant for 24 weeks. A few days ago, I went to have a teratectomy and a cleft lip examination. Maybe the baby is shy and always turns her back, so that the pregnant mother can't see her face clearly after several times of examination. At the end of the week, I went home with my friends to have a check-up. This time, the baby was quite obedient, and finally I could see the baby's face clearly. If the pregnant mother wanted to take a good look at the baby, she printed out the four-dimensional picture of the baby. Once printed, it didn't matter. The mother looked at the baby's "picture" and couldn't laugh or cry! So how does color Doppler ultrasound say pregnancy?.

How does color Doppler ultrasound say pregnancy?

First: Generally speaking, four-dimensional color Doppler ultrasound can be done at any gestational age, but it should be emphasized that there are disputes about doing four-dimensional color Doppler ultrasound at early pregnancy (before 12 weeks of pregnancy), and the development of each organ of the baby is not perfect. Therefore, for the sake of safety, it is suggested that after 20 weeks of gestation, the limbs and main organs of the fetus have all developed, and the amount of amniotic fluid is large, which is suitable for fetal malformation screening. At this time, it is the best time to do four-dimensional color Doppler ultrasound.

Second, compared with other ultrasonic diagnosis processes, four-dimensional color Doppler ultrasound can observe the dynamic movement of human internal organs in real time. Timely detection of fetal abnormalities can provide accurate scientific basis for early diagnosis of fetal congenital surface malformations and congenital heart diseases. In the past, B-ultrasound equipment can only check the physiological indicators of the fetus, while four-dimensional color ultrasound can also check the body surface of the fetus, such as cleft lip, spina bifida, brain, kidney, heart, bone dysplasia and so on, in order to treat as soon as possible.

Third: before the four-dimensional color Doppler ultrasound examination, pregnant women had better put on their coats and trousers separately instead of one-piece clothes, so as to avoid unnecessary trouble.

matters needing attention

In the examination of four-dimensional color Doppler ultrasound, doctors mainly check the fetal facial development, heart, brain, spine and other developmental defects through the examination instrument. If the fetus is found to have abnormal performance in the examination process, the examination time may be relatively long. Pregnant mother must keep a good attitude, the whole examination process will last about 20 minutes, pregnant mother must be patient.
