What is fetal 4D color ultrasound? What is four dimensional color ultrasound?

Four-dimensional color ultrasound can display the real-time dynamic image of the unborn baby in the womb of a pregnant woman, and you can see the development status of the fetus, or the real-time living image of other internal organs. To provide accurate scientific basis for early diagnosis of fetal congenital malformations. The best time to do a 4D examination is at 22 to 26 weeks of pregnancy, when the amniotic fluid is sufficient to facilitate the examination

Generally, the color ultrasound we receive during the prenatal examination in the hospital is two-dimensional ultrasound, and even the ultrasound screening and fetal malformation screening we carry out at 20 to 24 weeks are also two-dimensional ultrasound, because two-dimensional ultrasound is enough in the general screening of fetal structural malformations. On the basis of two-dimensional ultrasound, a three-dimensional reconstruction is done, which we call three-dimensional ultrasound, and the continuous plus a concept of time, there is a first-class video, which may be called four-dimensional ultrasound. Four-dimensional ultrasound is mostly seen in some institutions for fetal testing, and is not required by hospitals to examine the fetus due to medical conditions.

Hello to do this four-dimensional color ultrasound, there is no effect on the fetus, this is to observe what deformities the child has in appearance, under normal circumstances, 24 weeks to 28 weeks of pregnancy can do four-dimensional color ultrasound, I think 22 weeks may be a little too early to do.

Hello: The four-dimensional color ultrasound diagnostic instrument is currently the most advanced color ultrasound equipment in the world, which can intuitively and three-dimensionally display the three-dimensional structure of human organs and dynamically and observe the three-dimensional structure in real time, while the previous two-dimensional imaging technology can only show all aspects of human organs. In obstetrics and gynecology, four-dimensional color ultrasound can perform ultrasound examination on the fetus, which can show the color, face, and development of various organs of the fetus in three dimensions, and even the state of the fetus in the mother's body can also be observed; It can be early diagnosis of fetal malformations, such as cleft lip, cleft palate, abnormal bone development, cardiovascular malformations, etc.

I wish you good health

Now according to the four-dimensional color ultrasound is to leave a fetal period of the commemoration of their baby as a permanent souvenir, in fact, four-dimensional color ultrasound is three-dimensional color ultrasound plus a time dimension, dynamic three-dimensional. It can clearly record the dynamics and appearance of the baby in the mother's womb, so that every expectant father and mother-to-be can clearly see the baby.

Four-dimensional color ultrasound, which is the four-dimensional medical color ultrasound imaging technology, can also be used to refer to the examination of this technology or the instrument that implements this technology. Four-dimensional color ultrasound is based on three-dimensional medical color ultrasound imaging plus the fourth dimensional time vector, that is, 4D ultrasound technology is to use 3D ultrasound images plus time dimension parameters. 4D medical ultrasound imaging technology is the latest medical ultrasound imaging technology since entering the 21st century, which can obtain three-dimensional images in real time, beyond the limitations of traditional ultrasound.

Four-dimensional color ultrasound can intuitively and three-dimensionally observe the growth and development of the fetus through four dimensions. For example, through four-dimensional color ultrasound, you can see the appearance of the fetus clearly, and can more accurately judge whether the fetus has congenital malformations. It is clinically recommended that pregnant women need to undergo 3-4 four-dimensional color ultrasound examinations throughout pregnancy, and NT examinations, that is, nuchal translucency examinations, should be performed at 11-14 weeks of pregnancy; Four-dimensional ultrasound examination should be performed at 24-28 weeks of gestation to determine whether the fetus has structural abnormalities; At 30-32 weeks of gestation, color ultrasound should be rechecked to verify fetal malformations; During term, color ultrasound should be performed to evaluate amniotic fluid volume, placental function, and fetal weight.

Four-dimensional color ultrasound is a means to check the development of the fetus in utero through the abdomen, and it is also a means to screen for fetal malformations. It is generally done between 22 weeks and 28 weeks of pregnancy, because the fetal limbs and its organs are basically developed during this period, and at this time you can clearly see whether there is a malformation, which is an important examination method to prevent the birth of a malformed fetus, and it is recommended that every pregnant woman should do it.

Four-dimensional color ultrasound is the most basic color ultrasound in contemporary times, which can screen fetal malformations and clearly see the baby's development status in utero. At the same time, four-dimensional color ultrasound does not have radiation such as rays, light waves and electromagnetic waves, and has no effect on the body of pregnant women.

The four-dimensional color ultrasound diagnostic instrument is currently the most advanced color ultrasound equipment in the world. The result: the ability to display real-time dynamic images of your unborn baby, or other human internal organs.

The sex of the fetus can be known through four-dimensional color ultrasound, and gender identification is prohibited in China.

The best time for expectant mothers to do four-dimensional color ultrasound for the first time is 22-26 weeks of pregnancy, which can detect fetal body surface, bone, and cardiovascular malformations, which is a kind of deformity examination.

Four-dimensional color ultrasound is the world's most advanced color ultrasound equipment, which can observe the growth and development of the fetus in utero from multiple directions and angles, and provide accurate scientific basis for early diagnosis of fetal congenital body surface malformations and congenital heart diseases.

The purpose of four-dimensional color ultrasound examination is to rule out malformations of fetal organ development. Because the baby's growth and development in the second trimester of pregnancy is basically perfect, and the amount of amniotic fluid is large at this time, it is suitable for B-ultrasound doctors to screen for abnormal development of fetal organs, and it is generally recommended to conduct fetal four-dimensional color ultrasound examination at about 24 weeks of pregnancy.
