After becoming pregnant, women need to undergo several ultrasound examinations to detect the specific condition of the fetus. When performing four-dimensional ultrasound, if the fetus is facing the mother, it cannot be examined. Many pregnant women need to go to the hospital several times due to this reason. So, how does a four-dimensional ultrasound pass through in one go?

1. The best time to perform four-dimensional ultrasound is between 24-28 weeks of gestation. During this period, not only is the fetus basically formed, but the amniotic fluid is also abundant. Taking a four-dimensional ultrasound during this time period produces clearer images.
2. Pregnant women usually need blood and urine tests, as well as fetal heart rate and blood pressure measurements for prenatal check ups. When doing a four-dimensional ultrasound, if the fetus does not cooperate, it may not be possible to perform it for the whole day. The most active time for the fetus is usually around 8am, so pregnant women should undergo 4D ultrasound at this time.
3. Before undergoing 4D ultrasound, pregnant women should relax and avoid feeling nervous. When pregnant women are nervous, the fetus can feel it. When the fetal orientation is poor, it is difficult to change, which can prevent pregnant women from undergoing 4D ultrasound at once.
4. When conducting a four-dimensional examination, if the fetus is uncooperative and does not like to move, you can eat some sweets, coffee, or chocolate in moderation to increase the baby's excitement and make them move.
