Where to take 4D photos

In addition to allowing pregnant mothers to see the appearance of their baby, the four-dimensional color ultrasound also provides accurate scientific evidence for the early diagnosis of congenital epidermal malformations and congenital heart diseases of the fetus. Therefore, doctors recommend that pregnant mothers do four-dimensional color ultrasound examinations within 24-30 weeks to carefully observe the fetus's movements to determine the growth and development of the fetus. So, what are the common problems of 4D color Doppler ultrasound?

Where to take 4D photos

The four-dimensional examination is usually carried out in the anesthesia department of hospitals at the county level or above, and is performed by a professional fetal ultrasound physician. A basic fetal ultrasound examination, also known as a four-dimensional examination, should be performed during the 20th to 24th week of pregnancy. This examination is mainly to rule out some congenital tectonic abnormalities of the fetus. It needs to be carried out by a qualified county-level or above hospital. If any abnormality is found, it needs to be properly handled.

Frequently Asked Questions about 4D Color Doppler Ultrasound

1. The best time to check the four-dimensional color ultrasound for a single pregnancy is between 24 and 30 weeks of pregnancy, and for twins it is between 22 and 23 weeks. Because the fetal structure at this stage has been formed, the baby's size and amniotic fluid are moderate, the activity space in the uterine cavity is large, the echo effect of the fetal bones is relatively small, and the examination image is clearer. If the inspection time is too early, the best inspection effect cannot be achieved.

2. Traditional B-ultrasound requires fasting and holding urine before the test. However, whether you need to hold your urine when doing a four-dimensional color ultrasound depends on the number of weeks of pregnancy. You need to hold your urine when you are in a younger state, but you no longer need to hold your urine as you get older. Generally, you no longer need to hold your urine when doing a four-dimensional color ultrasound after four months of pregnancy. Thirty minutes before doing the four-dimensional color ultrasound, it is recommended that pregnant mothers eat something and drink a few drops of water, which can increase the baby's fetal movement.

3. Before the four-dimensional color ultrasound examination, pregnant women should wear comfortable and loose clothes. It is best to wear their tops and jeans separately for easy examination. In the four-dimensional color Doppler ultrasound examination, the doctor mainly uses the examination instruments to examine the fetus's current facial development, heart, brain, spine, etc. to see if there are any development defects. If the fetus is found to have deformities during the examination, the examination time may be relatively longer. Generally the entire inspection process will take about 30 minutes.

4. Four-dimensional color ultrasound can observe the development of the fetus in the pregnant mother's abdomen from all directions and angles, providing a more accurate basis for the early diagnosis of congenital epidermal malformations and other diseases of the fetus. For example, it can promptly deal with abnormalities such as cleft lip and palate, spina bifida, and incomplete development of the brain, kidneys, heart, and bones, so as to facilitate early treatment and increase the probability of eugenics. However, due to the limitations of ultrasound technology, not all malformed fetuses can be detected, that is, the ultrasound diagnosis accuracy rate cannot reach 100%.

Four-dimensional color Doppler ultrasound examination items

The biggest advantage of four-dimensional color Doppler ultrasound is to detect and screen fetal malformations, and provide accurate scientific evidence for the early diagnosis of congenital epidermal malformations and congenital heart malformations of fetuses. Compared with other ultrasonic diagnosis processes, previous B-ultrasound equipment can only check the physiological indicators of the fetus, while four-dimensional color ultrasound can also examine the fetus's body and screen for fetal malformations: such as cleft lip and palate, spina bifida, and hypoplasia of the brain, kidney, heart, and bone marrow, so as to facilitate faster treatment. In addition, four-dimensional color ultrasound also has another function. That is to take a personal portrait of the baby in the belly. Through four-dimensional color ultrasound, you can see the beautiful postures of the fetus in the uterine cavity, such as yawning, stretching, sucking fingers, etc. Some parents had already completed the deformity check and made a special trip to take photos of the fetus. They thought it was a precious remembrance for their children. The four-dimensional color Doppler ultrasound examination items include:

1. The baby’s facial deformity: such as cleft lip and palate.

2. Central nervous system: anencephaly, hydrocephalus, microcephaly, spina bifida and meningocele.

3. Digestive tract: navel intestinal protrusion, visceral organ eversion, gastrointestinal atresia and megacolon, etc.

4. Urinary and reproductive system: hydronephrosis, polycystic kidney disease, megacystis, and urethral obstruction.

5. Other deformities: short limbs, conjoined twins, cleft lip and palate, and four-chamber heart.

6. Too much or too little amniotic fluid, etc.
