The difference between system color Doppler ultrasound and four-dimensional color Doppler ultrasound

The difference between system ultrasound and thinking ultrasound is very big. The instrument used by system ultrasound is Doppler imaging instrument, which can check the whole body of fetus, such as head and abdomen, heart and spine. System color ultrasound includes two-dimensional color ultrasound and four-dimensional color ultrasound. Four-dimensional color ultrasound can check the development status of fetus in a three-dimensional and dynamic way. Fetal cardiovascular abnormalities can also be examined, so fetal abnormalities can be ruled out as early as possible.
