The secret of the second trimester: four-dimensional ultrasound, also known as abnormal examination, is an important milestone for every pregnant mother. In the second trimester, the fetus is of moderate size, and there is enough room in the uterine cavity, so doctors can observe every development detail of the fetus more accurately.

golden opportunity

22-24 weeks of pregnancy, no more than 26 weeks, is the best time for four-dimensional ultrasound examination. At this time, the size of the fetus is moderate, and doctors can clearly observe the growth and development of every important organ of the fetus to ensure the health of the baby.

Magic beyond two dimensions

Four-dimensional ultrasound transcends two-dimensional magic: it is not only an upgraded version of two-dimensional ultrasound, but also a dynamic and three-dimensional VCR image. Imagine what a wonderful picture it is to see the baby's little heart beating and his little hands and feet dancing in the dynamic image!

Large-scale anomaly inspection

Large-scale abnormal examination: this is actually a systematic prenatal ultrasound examination in the second trimester. It can systematically screen various organs of the fetus through ultrasound to ensure that there is no major abnormality in the baby's body structure. Such as anencephaly, severe encephalocele and open spina bifida. Can be found by large-scale teratology examination.

The best time for large abnormal resection

20 to 24 weeks pregnant. The choice of this time period is well thought out. The fetus is too small and the organs are underdeveloped, which is not conducive to observation; The fetus is too big and the space for activities is limited, which will also affect the doctor's examination. In addition, finding too many anomalies will increase the difficulty of handling anomalies.
