How does the duration of the procedure for MRI of the brain and other organs

1 Magnetic resonance tomography survey

In modern medicine, this method of studying the human brain is considered to be the most effective in comparison with other methods of revealing pathologies of internal systems of the body. This method has some advantages over other diagnostic methods, such as ultrasound pathology detection or computer diagnostics. Here are some of these advantages:

1. A wider diagnostic ability.
2. The ability not to affect the skin of the patient being examined.
3. No harmful effects on the human body.
4. Highly informative.
5. The ability to combine with computer diagnostics, while sharply increasing the accuracy of the results.

But the magnetic resonance method of human research has some drawbacks:

1. The cost of the procedure is quite high due to the availability of expensive equipment.
2. The duration of the examination is higher than using other methods, for example, ultrasound equipment or computer diagnostics.

Disadvantages of using a magnetic resonance tomograph are completely compensated by the accuracy of the diagnostics performed with this device. Therefore, every year there are new samples of this technology and, despite the higher price, are included in equipping modern medical centers.

2 Carrying out the

study Before the procedure, the doctor always warns the patient that using this type of examination takes quite a long time. In this case, the patient will need to remain in the state of immobility of the entire session. The person is put on a special moving table, which, when the unit is turned on, rides inside the cylindrical chamber, where the human body is being examined by low-intensity x-rays.

Almost all this time the patient should be immobile, and the process of research often takes from 20 to 60 minutes. Therefore, doctors before the session of magnetic resonance imaging find out from a person whether he suffers from claustrophobia. This is necessary, since most medical institutions have closed-type tomographs, that is, the patient is in a closed cell for a long time.

Very often, children are led to the examination, many of whom are afraid to be alone in an unfamiliar place, and even more so in an enclosed space. Therefore, doctors should take into account this factor. In some clinics, when performing a CT scan, doctors, with the consent of the parents, use narcosis for babies and teenagers during the session - this gives the necessary immobility of the child in the installation chamber.

But from this vicious circle there is a way out. Already in many hospitals and diagnostic centers are mounted together with standard closed-type magnetic resonance tomographs and their analogues, which are open platforms. On them, without fear, a patient suffering from claustrophobia and any child can lie.

3 Time required for

survey How long does it take to get the required data with a magnetic resonance tomograph?

The exact figure does not exist, since everything depends on the type of organ of the human body that needs to be examined.

Therefore, for the approximate calculation, use the following average statistical data obtained from the daily practice of the doctors of the magnetic resonance imager:

1. If the patient has brain structures, the usual duration of the procedure is about 20 minutes.
2. Approximately the same number lasts and the use of a tomograph in the preparation of a myelogram to study the structures of the patient's bone marrow.
3. If you need to examine the human spinal column with the use of the magnetic resonance method, then the session lasts about 25 minutes.
4. In the event that it is necessary to conduct a study of the whole organism or separately of its different parts, the duration of the procedure is significantly increased. With such a survey, any person has to remain motionless in the camera for at least 40 minutes. Often this is the minimum time, since in most cases the session lasts about an hour, and sometimes more.

The above-mentioned time intervals are not final, since here we must add the term of preparation of the magnetic resonance tomograph to the procedure itself. Therefore, doctors ask patients to come to the installation for 15-20 minutes before the beginning of the survey.

If a magnetic resonance tomograph should be examined by a child, doctors sometimes use medications with sedative properties. In such cases, they ask the parents to bring the baby for half an hour or an hour before the main examination procedure, since the introduction of the sleeping pill to the child takes place 15 minutes before.

After the study on the magnetic resonance imager is over, the child must remain in the clinic for some time until the effect of the sleeping pills stops and he wakes up. In this case, the examination session can take from 3 to 6 hours.

The very procedure for studying the human body on a tomograph is relatively safe, since low X-rays are used in the instrument.
