Four-dimensional four-dimensional ultrasound

Four-dimensional color Doppler ultrasound is the most advanced equipment at this stage, especially in obstetrics, the utilization rate is relatively high, widely used in clinical applications. The use of 3D stereo imaging technology to observe the development of fetal system structure, and whether there is congenital malformation in fetal system structure. Normal in the whole pregnancy process needs to do three four-dimensional color Doppler ultrasound, the first four-dimensional color Doppler ultrasound selected between 11 weeks and 14 weeks of pregnancy, detect the thickness of the fetal neck transparent layer combined with Down screening results to screen the risk rate of Down syndrome. The second examination is to detect the presence of abnormalities in the fetal system structure at 24 to 28 weeks of pregnancy. It can also detect whether the various indicators of the fetus are consistent with the gestational age and the condition of the amniotic fluid and placenta. The image options are very clear to provide a powerful auxiliary diagnosis for the clinic. At 32 weeks of pregnancy, the fetal four-chamber heart and other developmental indicators are detected.
