There is no need to have any magic trick to make 4D successful at one time, choosing to have 4D ultrasound examination at 22~26 weeks of pregnancy has the highest one-time success rate; most of the 4D ultrasound is successful at one time, and only in the case of discovering suspected abnormalities of the fetus, it may be necessary to carry out a second 4D ultrasound, such as the internal structure of the head as well as suspected abnormalities of the heart structure, and so on.
The main purpose of 4D ultrasound is to screen for fetal malformations, which is aimed at whether there are abnormalities in the development of the internal organs and body limbs of the fetus in the womb, such as observing whether there is cleft lip and palate, limb deformities, cranial and cardiac malformations in the fetus in the womb, etc. If the fetus is found to have unalterable deformities, it is necessary to terminate the pregnancy as soon as possible.
In order to improve the accuracy of 4D ultrasound, it is recommended that 4D ultrasound be performed between the 22nd and 26th weeks of pregnancy, because at this stage, the internal structure of the fetus is displayed more clearly, the internal organs are well developed, and the fetus is more active, etc., and the 4D ultrasound imaging achieves satisfactory images.
To do four-dimensional ultrasound you need to make an appointment at the hospital in advance to avoid the fetus is too big resulting in missing the best time for four-dimensional ultrasound examination, if you have symptoms of physical discomfort, you should go to the hospital in time to consult the physician’s guidance.
