How to make an appointment for 4D color Doppler ultrasound

Four-dimensional color ultrasound is a B-ultrasound for screening fetal anomalies. It must be done during pregnancy. The best time to check is when you are 25-28 weeks pregnant, when you can clearly see the growth and development of each organ of the fetus. Generally speaking, hospital outpatient appointments can be made online, so what is the booking process for four-dimensional color ultrasound? Let’s learn about it below.

How to book 4D color Doppler ultrasound

It is best to do a four-dimensional color ultrasound during the 6th to 8th month of pregnancy. At this time, the baby's development is basically complete, and the four-dimensional color ultrasound can be used to clearly see the growth and development of the baby's head, face, and limbs, and to check whether there are any deformities. When booking a four-dimensional color ultrasound, you can communicate with the doctor after the prenatal check-up and book the four-dimensional color ultrasound immediately. When the promised time comes, the doctor will actively call to inform you. When scheduling a four-dimensional color ultrasound, try to choose a time when the fetal movement is relatively frequent, so as to increase the comprehensiveness of the observation of the fetus. Therefore, pregnant women can observe the time and frequency of fetal movements in advance, and do not need to be fasting or hold urine for four-dimensional color ultrasound.

Four-dimensional color ultrasound is performed at 22-26 weeks of pregnancy. At this stage, the fetus is relatively small and can move freely in the uterus. The fetal skin is also relatively plump, which is very suitable for four-dimensional ultrasound imaging examination. If you do a four-dimensional color ultrasound too early, the fetus may not have taken shape yet, which makes the examination meaningless.

When doing a four-dimensional color ultrasound examination, pregnant women do not need to be on an empty stomach, but should eat more, so that the fetus has the strength to exercise, thus making the examination more effective. In order to facilitate the inspection, pregnant women are advised not to wear one-piece clothes, such as overalls, but to wear the jacket and jeans separately, which can make the inspection more complete. And you should walk more before doing the four-dimensional scan, so that you can take a picture of the back of the fetus more quickly.
