4D Ultrasound And What Is The Difference Between 3D – 4D?

4d ultrasound

4D ultrasound helps the doctor observe and detect abnormalities and abnormalities in the fetus. Are there any mothers who would not expect the moment to see the first vivid pictures of the baby in the abdomen?. In the age of advanced medical technology. 4D ultrasound technology allows you to see clearly every movement of the baby.

What is 4D ultrasound mean?

4D ultrasound will use high-frequency sound waves to convey the full motion of the baby in the womb. For 3D ultrasound, mothers can see three-dimensional images of the baby. 4D ultrasound can produce clearer effects and images similar to watching live video. Using this technology, the mother can fully see the baby’s expressive state, even if she is yawning or smiling.

Operational principles

At first, the gourd will be asked to place his or her back on the back of the examination table. Afterward, the doctor will apply a special gel to the abdomen, which will help to transmit sound waves. The doctor will keep a probe (the transducer) across the mother’s abdomen, moving in circles to get the best image possible.

A device called a transducer will be moved along the mother’s abdomen during the ultrasound to send sound waves through the abdomen and uterus. Sound waves travel through the abdomen and through the womb of the mother’s body and are returned as echoes. The screen will receive the feedback wave and simulate the screen again.

When the baby moves or kicks, the gourd will be able to see the images that appear on the ultrasound screen.

The results you receive after a 4D ultrasound may vary depending on your doctor. Sometimes you will get a baby picture, maybe even a 4D video that records your baby’s movements.

What is the difference between 3d and 4d ultrasound?

What is the difference between 3d and 4d ultrasound?

4D ultrasound or 4-D ultrasound is built on the basis of 3D scanning technology. One more dimension here is time. In essence, 4D pregnancy is the fetal movement in real time. As your baby moves, wriggles, frowns, wrinkles, thumbs up, eyes open and closes, you can see these movements on the scanner as it happens.

The technology used to make a 4D ultrasound makes this ultrasound more expensive and is not usually part of the regular obstetric service. If parents want to perform 4D pregnancy, they will have to pay for the service themselves.

3D ultrasound is also known as elective ultrasound, as it is not designed to replace standard obstetric procedures as 2D ultrasound. 3D ultrasound makes it easier for parents to perceive bonding to the fetus rather than a medical requirement such as 2D ultrasound.

Difference between ultrasound types

During pregnancy, the mother will undergo a variety of different ultrasound: 2D ultrasound, 3D, 4D, Doppler ultrasound. So what is the difference between these types of ultrasound?

2D ultrasound is the most popular and classic ultrasound. If the pregnancy is normal, it may be enough for a mother to have a 2D ultrasound. a With this type of ultrasound, the image that the mother receives will be the black and white shape of the foreskin or fetal profile.

3D and 4D ultrasound are similar in that they create vivid images of depth to mothers and doctors to see each corner of the baby. These images are assembled from a variety of 2D ultrasound images and processed with a modern technology. Other 3D 4D ultrasound is where the mother and the doctor can see the baby’s movements.

With a doppler ultrasound, a technician or doctor will use a hand-held device to surf the mother’s abdomen with the help of a specialized gel to record a baby’s heartbeat. The sound of heartbeats will be amplified by a loudspeaker so that the mother and the doctor can listen.

When to take 4d ultrasound?

There are a number of differences between hospitals regarding time requirements for the 3D ultrasound and or 4D. Many places suggest that optimal timing is between 27 and 32 weeks of gestation, while others suggest that between 26 and 30 weeks.

The fetus does not have enough fat to fully display the facial features so the quality of ultrasound and imaging will not be as clear as later. Wait a little longer and patience will bring you more benefits!

Your doctor will give you the best advice. However, the ideal time to perform 4D ultrasound is usually around the 27th to 30th week. There are also many sisters, so 4D ultrasound time is about 26 weeks earlier.

Prepare for an ultrasound

Prepare for an ultrasound

Each time 3D / 4D ultrasound lasts about 20 – 30 minutes. Experts encourage mothers to drink 8 to 10 glasses of water for at least 3 days before the ultrasound. Before the ultrasound, the mother should fast for 6 to 12 hours to empty the stomach, gas in the intestinal tract is reduced, avoiding obscuring the parts to be observed. In addition, you also need to urinate before going to the ultrasound table.

Ultrasound has been used for decades in obstetrics and there is no evidence that this method harms mothers and fetuses. The only thing you need to keep in mind when the ultrasound is on your doctor’s appointment, attention to the results and ask your doctor when questions arise.

Is it safe to do the 4d ultrasound?

Both 3D and 4D ultrasonography are not designed to replace standard obstetric ultrasound. Often, 2D medical ultrasonography is performed first to detect any abnormality in the mother and fetus.

Most studies show that 4D ultrasound is safe and does not pose a danger to the fetus. In addition, 4D ultrasound also helps physicians detect any fetal malformations for prenatal screening.

However, not all health facilities will meet the standard of medical facilities and equipment to conduct this ultrasound for both mother and baby. One thing is certain, too much ultrasound will affect the fetus.

Pregnant 4D is always the best choice for a mother to have the first vivid pictures of her baby. However, always consult your doctor before choosing this ultrasound. Also, ultrasound 4D is not a mandatory medical procedure like 2D ultrasound. So please consider and ask the insurance provider whether the cost of the ultrasound is covered.

The main purpose of the 4d ultrasound

The doctor concludes that your child is a boy, the rate is more accurate than the girl’s conclusion. In many cases, when the fetus has been 28 weeks but the testicles have not yet migrated to the scrotum, the doctor will mistake the boy for the girl.

Determination of gestational age by ultrasound

Through the size and shape of the fetus, the doctor can calculate the gestational age based on a comparison table. However, this determination is still erroneous, as the reconciliation table only shows how much of a pregnancy corresponds to a normal pregnancy.

Therefore, it is best to remember the first day of the last menstrual period and determine the gestational age starting from this date.

Determination of fetal health status

Ultrasound does not tell you if your baby is healthy or weak. Based on the ultrasound, your doctor tells you the size, diameter, crest length, femur length of the fetus. It can be confirmed that, at the time of ultrasound, the proportion of fetal body is balanced and corresponding to gestational age and the fetus has a potential congenital disease.

Extra abnormal results

Do not be alarmed when the results of the ultrasound record are “mesothelioma”: In this case, the doctor should record “the contraction of amniotic fluid unevenly.” The assertion of amniotomy can only be determined when the amniotic sac has broken (must be seen with the eye).

The doctor determines that the amniocentesis is not based on the amount and the resistance of the amniotic fluid; where the negative factor is less important. More or less amniotic fluid suggests abnormalities. However, abnormal conclusions must be made by specialized physicians.

  • Ectopic pregnancy.
  • Pregnant women.
  • Abnormal pregnancy.
  • Birth defects.
  • Problems with the amniotic fluid such as amniotic fluid, amniotomy.
  • Abnormal placentas: placenta placenta, placenta.
  • Slow growth in the uterus.
  • Other abnormalities in the uterus, ovaries and pelvic structure.

Avoid supersonic abuse

Current long-term effects of antenatal ultrasonography have not been proven, experts say, but no one can say that ultrasound is harmless to the fetus. Especially for fetuses under eight weeks of age – when placentas are being sorted, no one can be sure that any ray (including ultrasound) does not affect the formation of the placenta. that.

Scientific studies have shown that ultrasound does not cause significant effects on both the mother and the fetus. When your ultrasound, you do not feel any special pain or discomfort.

However, you should not overuse ultrasound. Excessive ultrasound is not only expensive for pregnant women but it can also affect the development of the fetus. Fetal ultrasonography (without restriction number), weight after birth is significantly lower than the case of ultrasound in accordance with the regulations. In addition, there are studies that have long-term effects of ultrasound such as hearing loss … (but studies have shown that ultrasound is not harmful to the baby and mother because the sound intensity is very low).

In addition, there is an interesting fact that the rate of birth defects is increasing in recent years. In addition to the environmental and genetic factors, ultrasound abuse can also be a risk factor for increasing the rate of fetal malformation.

Mothers who after referring to ultrasound articles of 4D pregnancy are accurate and have no effect on the fetus. This certainly adds important insights into the issue of ultrasound when pregnant. Wish you always healthy for your baby to develop the most comprehensive and please support the family.
