What's the difference between four-dimensional color ultrasound and three-dimensional color ultrasound?

Four-dimensional color Doppler ultrasound adds another dimension to three-dimensional color Doppler ultrasound. The differences between them are as follows:

1, three-dimensional color Doppler ultrasound is the three-dimensional dynamic display of color Doppler ultrasound, while four-dimensional color Doppler ultrasound is based on three-dimensional color Doppler ultrasound, just like showing a movie, showing the real-time dynamic image of the fetus.

2. Three-dimensional color ultrasound can only check the physiological indexes of the fetus, while four-dimensional color ultrasound can check the body surface of the fetus, such as cleft lip, spina bifida, brain, kidney, heart and bone dysplasia.

3. Four-dimensional color Doppler ultrasound is safer than three-dimensional. The four-dimensional color Doppler diagnostic instrument has no radiation such as rays, light waves and electromagnetic waves, and has no influence on human health.
