In order to prevent fetal developmental abnormalities, it is important to undergo prenatal check ups during pregnancy. There are many examination items that pregnant women do not know what to check, such as gross rejection and four-dimensional examination, which are easily confused. So, what is the difference between gross rejection and four-dimensional examination in pregnant women?
Four dimensional and large anomaly detection belong to two different examinations, with different contents and times of examination. When performing a four-dimensional examination, the fetal eye sockets and eyes are examined, as well as the distance between the fetal lips and eyes. Then, the child's neck is examined to see if there are any lumps present.
The major screening examination is to examine the organs of the fetus, as well as the surface structure of the fetus, so there is a certain difference between these two examinations. Pregnant women do not need to empty their stomachs or hold their urine when undergoing four-dimensional and large screening tests. The visual examination can determine whether the fetus is healthy from around 22 weeks to 28 weeks of pregnancy.
Pregnant women may have certain side effects when undergoing 4D ultrasound examination, and the time for 4D ultrasound examination should not be too long. It can be completed in about 20 minutes. During pregnancy, pregnant women must pay attention to a reasonable diet, maintain a balanced nutrition, and supplement the necessary nutrients for the body. During pregnancy, it is important to rest more and strengthen the body's resistance to prevent illness and discomfort.
