What is the difference between 4D and B-ultrasound

With the advancement of medical technology, B-ultrasound is now divided into many forms, such as black and white B-ultrasound, color ultrasound, and now four-dimensional color ultrasound. Their diagnostic functions are different. For example, there is a certain difference between four-dimensional color ultrasound and B-ultrasound. Four-dimensional color ultrasound has a sense of space and will form a three-dimensional image. When conducting prenatal examinations, four-dimensional color ultrasound can provide a more intuitive and clear image, which is something that ordinary B-ultrasound cannot do.

What is 4D Color Doppler Ultrasound?

Four-dimensional color ultrasound is also called four-dimensional B-ultrasound. It is a type of B-ultrasound. Its full name is four-dimensional color ultrasound diagnosis. It can display the real-time dynamic activity images of the fetus, which is very clear and intuitive. Therefore, it is increasingly widely used in gynecological prenatal examinations and some other medical examinations.

What is the difference between 4D and B-ultrasound

Simply put, ordinary B-ultrasound shows a plane, while four-dimensional color ultrasound is equivalent to a three-dimensional one. It can see the fetus from front to back, left to right, and top to bottom. Compared with ordinary B-ultrasound, it is more comprehensive, clearer and more realistic. B-ultrasound is now more widely used in cardiology, urology and gastroenterology. However, the impact of four-dimensional color ultrasound on the fetus is greater than that of B-ultrasound. Therefore, it is not recommended to perform a four-dimensional color ultrasound examination in the early stages of pregnancy. It is better to do it in the middle and late stages of pregnancy. In the early stages of pregnancy, you can use ordinary B-ultrasound examinations to perform some prenatal examinations. In the second trimester, when the fetal development is relatively stable, four-dimensional color ultrasound can be used to rule out fetal abnormalities or record the fetal activities. Ordinary B-ultrasound cannot do these things.

Through the editor’s explanation, do all the expectant fathers and mothers have a certain understanding of the relationship and difference between four-dimensional color ultrasound and B-ultrasound? In this way, you will not be confused and understand nothing during prenatal examinations in the future. It will also help you to better cooperate with the doctor's examination plan and fully understand the various conditions of the unborn baby. In this way, you can ensure the birth of a healthy and smart baby.
