Pregnant women have many prenatal tests during pregnancy, and as the pregnancy progresses, the items to be checked at each stage are also different. Each project also has its best inspection period. Pregnant women will also undergo prenatal check ups according to the doctor's arrangements. When is the general four-dimensional ultrasound examination conducted? Maybe the expectant mother doesn't know much about it. So, let's learn about it together.
When is the general four-dimensional color ultrasound examination
Generally speaking, 24-28 weeks of pregnancy is the best time to take a 4D ultrasound because around 24 weeks of pregnancy is the period of rapid brain development. During this period, the fetal structure has already formed, the size of the fetus and the amniotic fluid are moderate, and there is more space for fetal movement in the uterus. The impact of fetal bone echoes is relatively small, and the images are relatively clear.
Choosing the best time for a four-dimensional ultrasound examination not only provides valuable imaging records for children, but also plays a more important role in screening abnormalities. Four dimensional ultrasound examination can be performed during all stages of pregnancy, but the optimal time is between 20-26 weeks of pregnancy, when the major organs of the fetus have developed, the amount of amniotic fluid is appropriate, and the fetus has entered the abdominal cavity, making it easier to screen for fetal abnormalities.
How long can I have an ultrasound during pregnancy
Under normal circumstances, pregnant women should undergo a B-ultrasound examination in the early stages of pregnancy (around 12 weeks). Early or repeated B-ultrasound should be avoided. Performing ultrasound too early may cause the fragile and newly formed embryo to shake, which is not conducive to embryo development. Early pregnancy ultrasound is performed to determine whether pregnancy has occurred and the duration of pregnancy, provide reliable evidence for determining the due date, and promptly detect any abnormalities in embryonic development.
The optimal time for 4D ultrasound examination is between 24-28 weeks. If expectant mothers want to undergo the examination, it is best to do so during this period. This will result in more accurate and effective examination results, and can also better understand the growth status of the fetus. Expectant mothers may work hard during pregnancy, but I believe that as long as the baby grows up healthy, every expectant mother's efforts will yield good results.
