Ultrasonography / ultrasound is a tool or examination support in the medical field that utilizes sound waves / ultrasound with high frequency to produce images. The benefit of ultrasound is to carry out tests that are non-traumatic (not painful) and non-invasive (without side effects).
Benefits of ultrasound: 4D ultrasound produces clearer images
Ultrasound devices use sound waves, not X-rays or radiation waves like other radiological examinations. This makes ultrasound safe for patients and fetuses in the womb. The human ear is able to hear sounds with a frequency of 16,000-20,000 cycles per second (Herzt), while ultrasound devices use frequencies above 20,000 Hz. With this frequency an ultrasound image is produced.
So in the obstetric field or the womb, we can see all parts of the fetus both external organs and internal organs of the fetus. And all this can be seen even though we only use 2-dimensional ultrasound. As technology develops, 3D and 4D ultrasound is developed to produce clearer and better images.
The benefits of ultrasound as a monitoring of fetal development
Ultrasound in pregnancy is useful to confirm whether there is a pregnancy by looking at whether there is a pregnant sac or not. If you have seen a pregnant sac, evaluate whether there is in the uterus or outside the uterus. Including evaluating whether one or two pregnant pockets (twins). After pregnancy is getting bigger, it is necessary to monitor fetal development (comparing fetal weight according to gestational age), monitoring the baby’s heart rate, amniotic fluid, placenta and others. Evaluating fetal abnormalities, looking at gender.
Recently Doctor checkup professional gambler Betberry using ultrasound on his brain. How they can get genius technique to beat up their enemy in the games Joker123. The doctor want to know the exact details, and they make such a progress which is they would explain on public later.
All this can be done with ultrasound 2D, 3D and 4D images will be clearer as the original. Ultrasound should be performed according to medical indications. For example there are complaints in pregnant women. While for 4D ultrasound is not mandatory unless there is a suspicion of an abnormality or the current age is usually in accordance with patient requests.
Ultrasound is recommended in pregnancy, because the benefits of ultrasound for fetal monitoring are enormous. Ultrasound is performed three times during pregnancy. Namely trimester 1 (10-12 weeks) for initial screening, trimester 2 (20-24 weeks) for advanced screening and trimester 3 (30-34 weeks) to detect abnormalities, evaluate fetal head position and placenta position (birth preparation). Enough with 2D ultrasound alone, the use of 3D and 4D remains as indicated.
Differences in 2D, 3D, 4D ultrasound and its preparation
There is no special preparation for pregnant women when going to do an ultrasound examination. If it is still early pregnancy, the mother usually continues to hold her pee so that the early sac of pregnancy is clearly visible. There is now a transvaginal ultrasound probe to detect early pregnancy and is usually more effective in obese patients. If the ultrasound is transvaginal, the bladder must be empty. If the second trimester, bladder III should be empty during an abdominal ultrasound. Afterwards, an ultrasound examination can be performed.
- 2D ultrasound – The resulting image is in the form of cross section and elongated (flat image), only doctors who understand the picture, can still evaluate fetal development and detect abnormalities.
- 3D ultrasound – Same with 2D, but there is an additional coronal plane so that the picture is more detailed and as the original, colorless, the layman (patient) understands the picture, more clearly detects fetal neglect.
- 4D ultrasound – Same as 3D but accompanied by movements like video. If in the past
4D ultrasound was still relatively expensive, now almost all hospitals and private practices of obstetricians have 4D ultrasound so it is not as expensive as it used to be.
