Here is a list of most common questions one should want to ask before undergoing an ultrasound test:
1- Can ultrasound harm the baby?
Ultrasound uses high-frequency sound waves that help us generate medical images; As such, sound waves interact with the tissue producing movements at the cellular level and this is how they travel through the body. The ultrasound as such is harmless and does not generate any type of ionizing radiation as with x-rays or tomography.
2- Can perform many ultrasounds during pregnancy cause reflux?
There is nothing that relates to reflux to ultrasound. Reflux is related to the maturation of the gastroesophageal system, specifically with the proper functioning of the oesophageal sphincter that connects the oesophagus with the stomach. This sphincter or valve prevents gastric juices from returning to the oesophagus, which is not prepared to withstand the acidity of gastric juices.
This situation of "returning milk" It is relatively common and should stop happening one year after the baby's life; In any case, it is always advisable to visit the doctor to rule out that these types of conditions respond to something else.
3- Do ultrasound use radiation?
No, ultrasound does not use any type of radiation. Ultrasound uses high-frequency sound that is inaudible to humans. Humans listen in an acoustic frequency range of 20 to 20,000 Hertz. The ultrasound uses above 1 Megahertz that is 1,000,000 Hertz. The sound frequency above 1 Megahertz is not audible to humans or to most animals.
4- How long do the results of an ultrasound take?
This depends on the doctor doing the study. There is no rule about it. There are doctors who generate the report immediately after doing the study; or doctors who prefer to wait and make the report later to analyse the study in much more detail.
5- Do 3-D ultrasound use stronger waves than 2-D ultrasound?
No, it's the same ultrasound, just change the way the transducer works. The 3D / 4D transducer is essentially the same as that of 2D but is connected to a motor that moves it to be able to make volumetric acquisitions. Everything else is image processing in ultrasound equipment.
It is said easy but in reality, it requires a high processing capacity of the equipment to obtain good quality 3D or 4D images. It should be remembered that 3D or 4D not only serves to see the face of the BB, currently, volumetry is an advanced diagnostic tool for medical specialists, which allows them to assess in more detail the brain, heart, abdomen, limbs, and evaluation of blood flows, especially if a pathology is suspected.
7- With a 3D ultrasound is the prediction of the baby's sex easier and safer?
Not really, 3D ultrasound helps patients understand sex more easily. Volumetric ultrasound always depends on the foetus and its position.
8- Can a vaginal ultrasound harm the baby or hurt the mother?
No, pregnancy ultrasound does not harm the baby or the mother. The resolution of this application is advisable to make timely diagnoses during the first trimester, which will always be higher than the suprapubic ultrasound.
