The development and improvement of hardware diagnostic methods provides an opportunity to choose the method of conducting research, which is not limited by either the quality or the cost of the results obtained. However, not all diagnostic procedures combine high information content, affordability and the absence of negative effects on the body.
Particularly relevant is the issue of choice when it is necessary to conduct a study of the abdominal cavity organs, when the symptomatic picture is unclear and the causes of poor health may be hidden in a wide variety of diseases. Ultrasound, in this case, is the first step, which allows not only quickly and without harm to health to perform a study of the abdominal cavity and retroperitoneal space, but also to obtain as a result quite detailed information, which, if necessary, can be clarified by X-ray or MRI.
Often, diseases of organs such as the liver or pancreas require systematic monitoring of the course of the disease, and it is unacceptable to perform it using X-ray, and using MRI is expensive. The best option in this case can be considered ultrasound. However, a natural question arises: how informative is the ultrasound examination and how often can an abdominal ultrasound be done by an adult?
Let’s try to figure it out.
The effect of ultrasound on the body
The ultrasound method is based on the echo-location effect, which allows determining the position and shape of an organ in the projection of the ultrasound beam, the uniformity or heterogeneity of its internal structure according to the degree of reflection or absorption of directional ultrasound waves on a specific area of the human body.
It is worth noting that, despite the wide range of ultrasound capabilities that can bring biological tissue to a boil or destroy calculi in the gallbladder and kidneys, the power used in diagnostics is only one hundredth of the power of high-intensity ultrasound used in medical surgery.
An important role in leveling the danger of ultrasound is played by the duration of the examination. Everyone knows that conventional ultrasound takes a little more than 20, and in order to achieve even a slight heating of tissues with the use of much more powerful radiation, it takes about 3 hours.
Important! There is an assumption that a certain influence, ultrasound can have on the development of the brain of the embryo.
But since there is no complete evidence base capable of refuting or confirming this theory, the number of sessions of ultrasound procedures at the initial stages of pregnancy should be minimized.
Permissible number of procedures
The advantage of ultrasound performed on modern equipment is the possibility of obtaining a two-or three-dimensional computer image, which gives full information about the size, position of the test organ and the presence of hypo-or hyperechoic zones in it.
If necessary, the data obtained as a result of the procedure, if in doubt, can be re-reviewed. Observing certain rules of preparation for abdominal ultrasound, the essence of which is to exclude from the diet of any products that can affect the appearance of gas in the intestine, it is possible to reduce the time of the procedure to a minimum.
The frequency of diagnostics depends entirely on the main goal of ultrasound. For example, a planned study should be done once a year, and a focused study of the state of an organ, especially in the presence of pathological structures, can be carried out as many times as necessary.
There are no restrictions for multiple repetition of diagnostic procedures in the postoperative period, while the main purpose of ultrasound is to monitor the recovery of the body after surgery on the abdominal organs. When diagnosing the condition of the liver and pancreas, it is not recommended to eat any food 6-8 hours before the procedure, but if the main goal is to study the kidneys, then you need to drink at least 0.5 liters of water 0.5-1 hour before the ultrasound .
The abdominal organs studied with ultrasound include:
Very often, diseases of the abdominal cavity, such as fatty degeneration of the liver, cholelithiasis, can practically not manifest themselves and the presence of the disease, in this case, indicate indirect signs (poor complexion or yellowing of the eyes). Such conditions can last for quite a long time and be detected with a planned ultrasound scan.
Since an ultrasound scan with confidence can be considered a safe diagnostic procedure, it is necessary to undergo an examination at the slightest sign of violations of the internal organs:
- bitter taste in mouth
- persistent or paroxysmal abdominal pain
- discoloration of the whites of the eyes or skin
- loss of appetite
- increased drowsiness or fatigue
- diuresis disorders.
Also an indication for systematic monitoring of the state of the organs is the presence of chronic diseases such as diabetes, chronic cholecystitis or pancreatitis. If focal changes characteristic of malignant tissue degeneration are detected in the ultrasound picture, it is impossible to make an unambiguous diagnosis without a biopsy.
Regular ultrasound diagnostics allows you to get not only a real picture of the state of the internal organs, but also to assess the degree of effectiveness of the treatment, with the disease diagnosed earlier. Since there are no restrictions on ultrasound, the number of studies in a certain time interval can be any and depends on the decision of the doctor.
