The benefits of four-dimensional color Doppler ultrasound for pregnant women are clear and accurate. Four-dimensional color Doppler ultrasound is different from traditional B-ultrasound. The traditional B-ultrasound image is not clear, and the function of anomaly elimination is not strong. Four-dimensional color Doppler ultrasound not only has the function of high-definition shooting, but also has a powerful function of exception removal. Even the smallest deformity can't escape the "eyes" of four-dimensional color Doppler ultrasound.
Providing accurate scientific basis Four-dimensional color Doppler ultrasound can not only display the real-time situation of the fetus, but also observe the growth and development of the intrauterine fetus from multiple directions and angles, and check the various organs of the fetus one by one to see if the fetus is abnormal, thus providing accurate scientific basis for early diagnosis of fetal congenital body surface malformation and congenital heart disease.
Traditional B-ultrasound can dynamically track the fetus and only obtain static images. It is difficult for doctors to analyze the specific situation of the fetus through static images, while the images of four-dimensional color Doppler ultrasound are dynamic, so doctors can judge the development of the fetus according to the dynamics of the fetus.
Four-dimensional color Doppler ultrasound is ergonomically designed, and there is no radiation such as rays, light waves and electromagnetic waves, which has no impact on human health.
Take precious images of the baby in the belly as a souvenir. Four-dimensional color Doppler ultrasound not only has super teratogenic function, but also has powerful shooting function. When doing four-dimensional color Doppler ultrasound, you can capture every tiny movement of the fetus and make an album, leaving precious photos of the fetus at the age of 0.
The best time for pregnant women to do four-dimensional color Doppler ultrasound can be done in any gestational age, but it should be emphasized that it is controversial to do four-dimensional color Doppler ultrasound in the first trimester (before pregnancy 12 weeks). For the sake of safety, it is recommended to do fetal four-dimensional color Doppler ultrasound after 16 weeks of pregnancy. After 0/6 weeks of pregnancy, the fetal limbs and main organs have developed, and the best examination time is 24 -28 weeks of pregnancy. The amniotic fluid volume is more suitable for fetal malformation screening.
So, what are the precautions for four-dimensional color ultrasound?
Precautions for pregnant women to do four-dimensional color Doppler ultrasound 1. You don't need to hold your urine or have an empty stomach to do four-dimensional color ultrasound. Pregnant women refer to the need to go to the hospital for examination within the specified time.
2. Before the four-dimensional color ultrasound examination, it is best for pregnant women to wear shirts and pants separately. In the examination of four-dimensional color Doppler ultrasound, doctors mainly check the current facial development of the fetus and whether there are developmental defects in the heart, brain and spine. If the fetus is found to have abnormal performance during the examination, the examination time may be longer.
3. Due to the limitation of ultrasound technology, not all fetal malformations can be detected in fetal examination, that is, the coincidence rate of ultrasound diagnosis can not reach 100%.
4. The soft tissues such as ears, sex, genitals and jaw arch in fetal ultrasound examination are not within the scope of ultrasound examination.
5. Fetal limb examination does not include the number of phalanges and phalanges. Fetal four-chamber heart examination can only send 50%-60% of congenital heart diseases.
