Many expectant mothers, for the sake of the health of their unborn child, will go to the hospital for various examinations. Some expectant mothers are not familiar with the various functions of different examinations, such as B-ultrasound and 4D ultrasound. What are the differences between them? Let's learn more about it together with the editor!
The difference between super large screening and four-dimensional ultrasound
Four dimensional ultrasound is actually a slightly more advanced ultrasound examination than ultrasound, and there is no significant difference between the two. Big screening is an important examination, just like Tang screening for glucose tolerance, which is very important. It is usually done around six months in mid pregnancy, but the method to complete the examination is four-dimensional ultrasound!
Precautions for B-ultrasound examination
The duration of B-ultrasound should not be too long
Pregnant women should pay attention to the time of ultrasound examination, generally not exceeding 20 minutes, especially in the case of illness and fever. The ultrasound examination time should be faster and shorter, otherwise it will affect the health of mother and baby.
Ultrasound operation must be standardized
Pregnant women should pay attention to whether the operation of B-ultrasound examination is regular, and the scanning probe should not stay in the same position for a long time.
Before B-ultrasound examination, it is necessary to understand
Before undergoing ultrasound examination, pregnant women should have relevant knowledge, including whether they need to hold their urine and other precautions, in order to avoid delaying the examination time and increasing the number of examinations in the hospital, which may affect the fetus.
In fact, there is not much difference between ultrasound and four-dimensional ultrasound in detecting abnormalities. The two are interrelated but not the same. In addition, this article lists various precautions for pregnant women when undergoing ultrasound examinations. We hope that expectant mothers will not be careless when undergoing ultrasound examinations and will have a detailed understanding before proceeding.
