How to understand four-dimensional color ultrasound

Four-dimensional ultrasound examination can clarify the development of various organs of the fetus, and the specific development will be described in detail on the ultrasound report. After four-dimensional ultrasound examination, in addition to observing the fetal size seen by ordinary ultrasound examination, including the fetal biparietal diameter, abdominal circumference, femur length, fetal movement and amniotic fluid conditions, it can also see whether there are abnormalities in various systems of the fetus, such as nervous system, urinary system, body surface abnormalities or digestive system abnormalities, etc., but also can judge the fetal position and placenta maturity, placenta position and so on. Four-dimensional ultrasound examination is a dynamic stereoscopic observation, so it has unique advantages in examining fetal heart structure and function.
