What’s 4D Color Dopplor Ultrasound?
4D ultrasound also called four-dimensional color Dopplor ultrasound diagnostic apparatus, which is the world's top color ultrasound equipment. It possesses surface image to high solution screening of deformity of fetal limbs, meningeal bulging, cleft lip and palate, spina bifida and other congenital malformations, which help to detect and take solutions earlier.

Ultrasound scan is an important mean of detecting fetal malformations. If any malformation is detected, the gestation can be terminated in time. Usually 4D anomaly scan is arranged during 22-26 weeks, by then organs are developed and formed.
Color ultrasound can measure amniotic fluid volume accurately. It is critical to the fetal development as for too much or too little water would cause fetal malformation. However, ultrasound can show clearly the position of placenta, placenta hemangiomas, and its maturity etc., meanwhile, it can also diagnose of placenta previa and placental abruption as well.
