How long does a 4D color Doppler ultrasound examination take?

Compared with the previous two-dimensional and three-dimensional ultrasounds, four-dimensional color ultrasound can grasp the fetal growth and development status more comprehensively and can reduce the occurrence of fetal malformations to the greatest extent. Therefore, four-dimensional color ultrasound is an important method for screening fetal malformations. How long does it take to do a 4D color Doppler ultrasound?

How long does it take to do a 4D color Doppler ultrasound?

The time for four-dimensional color ultrasound generally takes about 30 minutes to 1 hour. The actual time depends on the specific situation of the expectant mother and baby. If the baby cooperates, the normal time will be relatively shorter. As the most accurate and scientific instrument currently used to detect fetal malformations, four-dimensional color ultrasound requires comprehensive and careful examination when conducting four-dimensional fetal malformation screening.

The full name of four-dimensional color ultrasound is four-dimensional color ultrasound examination instrument, which is the world's most advanced color ultrasound equipment. Because four-dimensional color ultrasound can display surface images, developmental malformations such as cleft lip and palate, incomplete limb development, meningeal herniation, spina bifida, and abdominal cleft can be detected more clearly. The diagnostic data of four-dimensional color Doppler ultrasound can also help doctors make judgments. "It is most important to check the growth and development of the fetus and screen for congenital diseases."

The best time for pregnant women to have a four-dimensional color ultrasound examination is between 20 and 28 weeks. Compared with other 3D ultrasound diagnosis processes, 4D ultrasound allows doctors to observe the dynamic movement of internal organs in real time. For example, doctors can judge the growth status of the fetus based on the fetal movement, and the accuracy of ultrasound-guided puncture can be improved by observing the three-dimensional movement of the puncture tube. This enables clinicians and anesthesiologists to test and detect a wide range of abnormalities, from vascular malformations to genetic syndromes.

Preparation before 4D color Doppler ultrasound examination

1. Four-dimensional color ultrasound can be performed at any week of pregnancy, but it should be noted that there are objections to doing four-dimensional color ultrasound during early pregnancy (before 12 weeks of pregnancy). For safety reasons, it is recommended to do fetal four-dimensional color ultrasound after 20 weeks of pregnancy.

2. After the 20th week of pregnancy, the fetus's body and major internal organs have already fully developed. However, during the 22nd to 26th week of pregnancy, because the fetal organs are more fully developed and the amniotic fluid flow is more, it is suitable for fetal malformation screening.

3. Abdominal four-dimensional ultrasound examination is not subject to time restrictions, but is only suitable for patients in mid- and late-term pregnancy.

4. Transvaginal four-dimensional ultrasound examination requires the bladder to be emptied and there is no need to hold urine. The examination can be performed anytime and anywhere, but attention should be paid to disinfection and sterilization to prevent infection during menstruation.
