Mothers-to-be who are pregnant with twins are more fortunate to try to endure as many stresses and complications during pregnancy than those with a single child, but for a pregnant mother to be able to have the two babies she wants at once, then these pains don’t seem unbearable. After all, there are two little ones inside the belly, so naturally they are taken seriously, including the 4D ultrasound exams during pregnancy, which cannot be missed. The high-definition 4-dimensional ultrasound to see the fetal baby, record the initial touch of life! So how to do 4D ultrasound for twins? It should be noted that it is more difficult to do ordinary ultrasound examination for twins, so pregnant women who are pregnant with twins should receive 4D ultrasound examination. The best time to do 4D ultrasound for twins is the same as for singleton, and it is better to do it between 22-28 weeks of pregnancy. However, there are some differences in each individual case, so it is recommended to contact your doctor before having 4D ultrasound so that he or she can analyze the best time for you to have 4D ultrasound. The difference between 4D ultrasound and normal ultrasound is that 4D ultrasound offers multifaceted applications in multiple areas including abdomen, blood vessels, small organs, obstetrics, gynecology, urology, neonatal and pediatrics. The result: the ability to display real-time dynamic moving images of your unborn baby, or other internal organs of the body. Compared to other ultrasound diagnostic procedures, the dynamic movement of the internal organs of the body can be observed in real time. Clinicians and sonographers can detect and find a wide range of abnormalities, from vascular malformations to genetic syndromes. 4D ultrasound can observe the growth and development of the fetus in utero in multiple directions and angles, providing an accurate scientific basis for early diagnosis of fetal congenital body surface abnormalities and congenital heart diseases. In the past, the ultrasound equipment could only check the physiological indicators of the fetus, but 4D ultrasound can also check the fetal body surface, such as cleft lip, spina bifida, brain, kidney, heart and skeletal dysplasia, in order to provide early treatment. It is no longer a fantasy to have a smart and healthy little baby and to make photos or VCDs of the baby’s appearance and movements so that the baby can have the most complete 0-year-old photo album.
