Prenatal prenatal screening is highly valued by every mother and is also a necessary examination. Compared to single births, twins still have certain differences. So the mother of twins felt troubled, how do twins eliminate deformities? What is the difference between prenatal screening and singleton pregnancy?
Due to the particularity of twins, choosing a regular ultrasound examination would be more difficult. Four dimensional ultrasound is a better choice for twin screening. However, what is consistent between twins and singleton fetuses is that the optimal time for both to undergo four-dimensional ultrasound is between 22-28 weeks of pregnancy. However, it cannot be ruled out that some people may have different specific situations, so it is recommended to consult a doctor before undergoing a four-dimensional ultrasound examination.
In addition to choosing the best time, the legitimacy and professionalism of obstetrics and gynecology hospitals can ensure the effectiveness of four-dimensional ultrasound, and only authority can avoid missed or ambiguous errors as much as possible. In addition to the optimal time mentioned above, an ultrasound examination at 20 weeks of pregnancy can already detect abnormalities.
However, more targeted prenatal screening should wait until 20-24 weeks, because at this time, the development of various organs in the fetus's body is basically mature, which makes it more convenient for doctors to observe. If problems are found at this time and pregnancy is terminated in a timely manner, it will not have too much impact on the mother.
