The research method using ultrasound is based on a banal echo. With the help of the sensor, the computer removes the reflections and a picture appears on the screen, which the specialist can understand.

Among the many methods of examination, ultrasound remains the most popular and fashionable. Thanks to this harmless method, you can immediately see the results without waiting for laboratory data.

But such simplicity and availability of ultrasound immediately led to some exaggeration. That is why it is worth considering the most popular myths about ultrasound.

All organs can be examined using ultrasound. Ultrasound can only recognize fluid-filled or sufficiently dense organs. Air becomes an insurmountable obstacle for such waves. That is why, so that such an environment does not interfere, a special ultrasonic gel is applied outside. For the same internal organs that are filled with air, ultrasound is, in principle, impossible.

With the help of ultrasound, any pathology can be determined. Ultrasound can only see anatomical changes and only in certain tissues, as already mentioned. Such research is unable to detect functional disorders. And the phrase that "no ultrasound pathology was detected" does not at all guarantee that everything is in order with health.

Ultrasound can be done before the doctor's examination or even refuse the latter. It should be understood that ultrasound is only an additional examination. It is worth going there with a presumptive diagnosis in hand. But it can be placed only after the examination of the patient by a doctor and questioning. To do an ultrasound just for the sake of interest and not knowing what to look for, there is no point. The examiner will not know what to look for. And before the doctor's examination, you can only do "ultrasound in dynamics". It implies an already known diagnosis, when it is necessary to identify the changes that have occurred.

On an ultrasound scan, you can see pregnancy already on the first day of the delay, or even the day before the expected menstruation. Uterine pregnancy can be clearly seen on ultrasound, starting from 7-10 days of delay. And there are several reasons. First of all, the ovum is too small in size, the apparatus has a limited resolution, it should be understood that the female body also undergoes natural functional changes. At such a short time, it is easy to confuse the onset of pregnancy with the onset of menstruation. Blood may accumulate in the uterus before external bleeding begins. That is why in such cases, for accuracy, it is recommended to repeat the ultrasound in another week.

To conduct an ultrasound scan, the body does not need to be specially prepared. This is true when it comes to preparing for an examination of the mammary glands, vagina, pelvis, kidneys or thyroid gland. But a more detailed examination of the same kidneys, as well as the bladder and external small pelvis, requires a filled bladder. Before performing an ultrasound of the abdominal cavity, you must follow a gas-free diet for three days, which includes, among other things, avoiding foods such as whole milk, grape juice, black bread, legumes and fresh vegetables. You must also take activated charcoal or other similar absorbent. If you do not follow these recommendations, then the intestines will fill with gas and block the abdominal cavity.

If there are changes in the body, then ultrasound will show them. There may be kidney stones in the body, which will not give the echo necessary for detection. Changes invisible to ultrasound can exist in the abdominal cavity and small pelvis (adhesions, for example). The accuracy of the method is on average 70% and varies depending on the diseases. So, for breast diseases, the accuracy of ultrasound is only 60-65%, while for X-rays it is 80-85%.

Ultrasound is an objective and accurate method. This research is initially subjective. Its accuracy directly depends on both the qualifications of the specialist and the class of equipment. So it turns out that on the same day you can be examined in different places and get different results. Therefore, a doctor is needed to evaluate the ultrasound.

Ultrasound is harmful to do during pregnancy. It is worth understanding what ultrasound is - it is an inaudible squeak of high frequency. It has no teratogenic effect, that is, it does not affect the fetus in any way. Long-term ultrasound can, on the contrary, increase the tone of the uterus. But after the end of the procedure, this effect will come to naught. So there are no contraindications for ultrasound as often as doctors require. Only here it is not worth deliberately frequenting, it will not give additional useful information. It is optimal to carry out such a survey every 30-45 days.

An ultrasound scan should not be done early in pregnancy. This myth continues the previous one. And the fault is that people lack deep knowledge of technology. In the early stages of pregnancy, an ultrasound scan may be necessary, if the gynecologist has questions about the development of the fetus, you must make sure that the pregnancy is not ectopic. Thus, with the help of ultrasound, it becomes possible to confirm some of the doctor's assumptions. The result depends on the experience of specialists who can consider the pathology. And this procedure, we repeat, is safe even in the early stages of pregnancy. The only thing to remember is that ultrasound should be done solely for the sake of confirming the diagnosis or the normal course of pregnancy. It is certainly not worth conducting such a survey just for the sake of curiosity.

Ultrasound should be done no more than three times during the entire pregnancy. This myth appeared because people do not understand where the limitation of three ultrasounds came from. In fact, this is not a rigid norm, but simply the minimum number of examinations that are required to fully monitor the course of pregnancy. Scientists have identified the timing at which potential problems with the fetus can be identified. It is believed that the first ultrasound scan is best done at 10-12 weeks, the second at 20-24 weeks, and the third from 32 to 36 weeks. But by agreement with the doctor, additional examinations may be needed, there is nothing to worry about.

Better to do a three-dimensional ultrasound. It seems to us that any new technology is preferable and more accurate than the old one. But every uzist, considering the device from the point of view of obtaining a result, for some reason always tends to a traditional, two-dimensional ultrasound, with a black and white picture. This technology does an excellent job with the task, in the case of pregnancy, showing all the important parameters of the development of the embryo and identifying possible violations. A three-dimensional ultrasound allows you to examine in detail all parts of the body of the future man, which makes the determination of gender unambiguous. 3D ultrasound allows parents to see how the baby stretches, yawns and sucks his fingers. Who will refuse such an opportunity, even if you have to pay for it? But from the point of view of medicine, three-dimensional ultrasound does not bring practical benefits in comparison with two-dimensional.

Three-dimensional ultrasound is a must for all parents-to-be. Nowadays, not all medical institutions have the equipment necessary for carrying out such a procedure, especially in public clinics. Even in private institutions that specialize in gynecology and obstetrics, an ultrasound scanner with powerful computer equipment is not always present. The same centers that offer a 3D ultrasound service charge an additional fee. I must say that such a service is quite in demand, because in its process it is proposed to record a video on a disc, so that it can then be shown to a grown-up child. Whether it is necessary is the personal choice of the parents, there is no medical indication for conducting just such an ultrasound.

A three-dimensional ultrasound is done in the same way as a two-dimensional one. In fact, there are still a few differences. The main thing is the image quality, as already reported above. And the time required for the examination is a little more. If in the traditional case it takes about 15 minutes, then a three-dimensional ultrasound will take from half an hour to 50 minutes.
