How many weeks of pregnancy is suitable for 4D color Doppler ultrasound

Between 20 and 24 weeks of pregnancy, a four-dimensional color ultrasound examination of the fetus can be performed to determine whether the fetus has organic lesions in the human visceral system. The best time for four-dimensional color ultrasound screening for fetal anomalies is between 22 and 24 weeks of pregnancy. At this stage, the fetus's internal organs are splitting and forming. Through the fetal four-dimensional color Doppler ultrasound, it can be found that the fetus's central nervous system, digestive tract, urogenital system, urinary system, respiratory system, face, and limbs are underdeveloped. Pay attention to regular prenatal check-ups.

Pregnant women undergo four-dimensional color ultrasound examinations, usually around 24-28 weeks of pregnancy. This is because at this stage, each organ of the fetus is basically developed and perfect, and it is an important stage for screening whether the fetus has any malformation. Through four-dimensional ultrasound examination, it can be found whether the fetus has some structural development abnormalities, such as enlarged renal pelvis, increased intestinal echo, and spotted strong echoes in the atria.

If the position of the fetus is not suitable for four-dimensional ultrasound screening during the examination, the pregnant woman can let the baby move around in the uterine cavity through appropriate activities and music, and then conduct another examination. If the four-dimensional ultrasound examination shows that the baby may have malformations, then we should conduct further comprehensive examinations to check for chromosomal abnormalities in the fetus.

Four-dimensional color ultrasound is usually best performed during the 20th to 24th week of pregnancy, when the amniotic fluid flow and fetal size are more suitable. If you are pregnant and plan to reach this gestational week, you usually need to make an appointment within one month in advance, because the inspection in this time period takes longer, the content is more detailed, and the number is also larger. According to the four-dimensional color ultrasound screening, most of the cases are generally not serious problems. You need to have regular pregnancy checkups. According to four-dimensional color ultrasound, you need to start diabetes screening at 24 weeks.
