We all know that ultrasound is divided into black and white ultrasound, color ultrasound. The color ultrasound is divided into three-dimensional ultrasound, four-dimensional ultrasound. The four-dimensional color ultrasound to see the appearance of the fetus are very clear, some pregnant women are more anxious to know the sex of the fetus, in the pregnancy period to find some medical institutions to take pictures of the sex of the fetus. So, Four-dimensional color ultrasound to see the gender must be accurate? In addition, 4D ultrasound adds time dimension parameters to these features, allowing real-time observation of dynamic moving images of the fetus.
In general, a 4D ultrasound can reveal large fetal malformations, such as congenital heart disease of the newborn, cleft lip and palate, hydatidiform fetus, polydactyly (toes), and malformations of the outer ear. However, 4D color ultrasound is not omnipotent, for example, newborn deafness, cataracts and so on can not be detected. Four-dimensional color ultrasound diagnostic equipment is currently the world's most advanced color ultrasound equipment, many pregnant women do four-dimensional ultrasound, will habitually ask the doctor whether the fetus is male or female. Although 4D ultrasound is able to see the gender of the fetus, during the examination, in order to avoid revealing the gender of the fetus, the doctor will take the initiative to avoid the gender characteristics of the fetus as well as the lower half of the body, and at the same time, in the post-production of the CD-ROM, the part that may disclose the gender of the fetus will also be dealt with.
So, although 4D ultrasound can detect the gender of the fetus, but according to the state regulations non-medical purposes to distinguish between male and female fetus is illegal, regular hospitals will not tell, imply the gender of the fetus through any means.
In fact, whether it's a boy or a girl, it's the fruit of a couple's love, and parents-to-be should be more concerned about whether the fetus is healthy and develops normally, rather than the gender.
4D ultrasound precautionsUltrasound is the use of four-dimensional color ultrasound diagnostic instrument to carry out the examination, can real-time acquisition of three-dimensional images of the fetus, is an advanced means of detection. Four-dimensional color ultrasound diagnostic instrument has excellent ergonomic design, is the use of ultrasound principle of production of a kind of instrument, there is no radiation, light waves and electromagnetic waves and so on, there is no effect on the health of the human body.
Due to the four-dimensional ultrasound diagnosis on the human body damage is small, can be repeated checks, diagnosis quickly and accurately, so it has become the first choice of obstetrics and gynecology diagnostic imaging methods for medical and scientific research to provide a more reliable basis for medical treatment, has become an indispensable auxiliary diagnostic tools. The color ultrasound is a kind of ultrasound, and there is no radiation, and only a short period of time swept through the human body, on the pregnant woman and the fetus and no adverse effects.
1, do four-dimensional ultrasound do not need to hold urine, also do not need fasting. Pregnant women refer to the need to go to the hospital within the prescribed time for the examination can be.
2, before the 4D ultrasound examination, pregnant women are best to wear their own tops and pants separately. In the four-dimensional ultrasound examination, the doctor is mainly through the examination of the instrument, the current facial development of the fetus, as well as the heart, the brain, the spine and so on there is no developmental defects to carry out a check, if the process of examination found that the fetus has a deformity manifestation, then the examination time may be relatively longer.
3, the fetal examination, due to the limitations of ultrasound technology, can not detect all fetal malformations, that is, ultrasound diagnosis can not reach 100% compliance rate.
4, fetal ultrasound soft tissues such as ears, gender, genitals and jaw arch are not included in the ultrasound examination.
5, the number of phalanges and phalanges are not included in the fetal limb examination, and the fetal four-chambered heart examination can only send out 50%-60% of the congenital heart disease.
