Color Doppler ultrasound is actually black and white, while 3D and 4D color Doppler ultrasound may be khaki when making 3D and 4D images. It is not that color Doppler ultrasound is color. It is called color Doppler ultrasound because it uses colors to mark indicators such as the heart and blood flow.
1. Hemodynamics
To put it simply, color Doppler is a high-definition black-and-white B-ultrasound coupled with color Doppler, which not only has the advantages of two-dimensional ultrasound structure images, but also provides rich information on hemodynamics, which can accurately reflect the physiological characteristics of various organs. And blood flow characteristics under pathological conditions.
2. More detailed body surface examination
Four-dimensional color Doppler ultrasound can observe the growth and development of the fetus in utero from multiple directions and angles, providing accurate scientific basis for early diagnosis of fetal congenital body surface abnormalities and congenital heart disease. In the past, B-ultrasound equipment could only check the physiological indicators of the fetus, while the four-dimensional color Doppler ultrasound can also check the fetal body surface, such as cleft lip, spina bifida, brain, kidney, heart, skeletal dysplasia, etc., for early treatment.
3. Is the umbilical cord around the neck clearer?
The resolution of color Doppler ultrasound is higher than that of general black and white B. Therefore, when more detailed examinations are needed, more doctors are willing to use color Doppler ultrasound. E.g:
Because color Doppler ultrasound can use color to mark blood flow, when the umbilical cord is wound around the neck, you will see a U-shaped or W-shaped blood flow on your baby's neck. It is clear at a glance whether the umbilical cord goes around the neck.
Ordinary B-ultrasound diagnosis of umbilical cord entanglement depends only on observing the pressure marks formed by the entanglement, but for those who are not obvious, the diagnosis is often missed, so color Doppler ultrasound can better judge.
