Today, one often hears about such a medical term as MRI. The question arises, what is the diagnosis of MRI? What is this new research method for? What are the contraindications and, conversely, when is it prescribed? Everyone needs to know the answers to these questions, because who knows, maybe in the future such a procedure will be simply necessary.
Medicine does not stand still, but is constantly evolving, looking for new methods to give people such a long-awaited he alth. The diagnostic method is, of course, not a miracle cure, but a warning factor that can help to cope with the disease at an early stage. Do not neglect the techniques that have already won a place in our lives.
What is MRI diagnostics
Magnetic resonance imaging is a method of studying internal organs and their tissues by influencing the body with nuclear magnetic resonance. A procedure that uses a magnetic field to create an image that is transferred to a computer. This procedure does not use x-rays.
Modern MRI diagnostics has become popular among a wide range of people with various he alth problems, as it is absolutely harmless and has no side effects. No medical procedure provides a better picture of a person's he alth than an MRI. In one session of tomography, you can learn about problems associated with the nervous system, musculoskeletal system and any internal organs.
In a short period, the whole picture of the ongoing changes in the human body opens up. If there are indications for such a study, it is better to use the doctor's recommendation to exclude a terrible disease. Research never hurts, especially those that do not harm the body. Better prevention than cure.
The history of magnetic resonance imaging
If you remember the story, the discovery of x-rays surprised all doctors. This technique literally immediately began to be used in practice, while magnetic resonance has not been studied for 20 years. And mentioning this technique, they date back to the pre-war period. Before World War II, German physicists were already working with magnetic resonance. Although this method was not common, it was already known.
In 1983, the first mass-produced MR systems appeared. In 1984, the first tomograph was installed. During all this time, the appearance of the device has not changed, but its capabilities have increased. Although this diagnostic method did not find recognition in the past, it is quite accepted today.
Without magnetic resonance imaging, complex operations are not performed, as doctors prefer to know what they are dealing with. The image clearly shows both the tumor and other abnormalities, so the surgeon can confidently do his job without fear of causing harm.
MRI diagnostic method
One of the most effective diagnostic methods in our time. This is a safe technique without radiation exposure to the body. It is used even for children and the elderly. During the examination, the patient lies on a special couch, which moves under the scanning device. The procedure does not give any physical load on the body and does not cause inconvenience. The problem arises only if a person is terribly afraid of a closed room, but in this case, anesthesia is used.
The sliding table moves to fix the diseased part of the body. Within an hour or a little more, depending on the type of study, the doctor gets a complete picture of the patient's he alth.
In what cases is magnetic resonance imaging prescribed
The possibilities of MRI diagnostics are very large, since a serious disease can be diagnosed within a few hours. Usually this procedure is prescribed for the following diseases, regarding:
- Brain.
- Spine and spinal cord.
- Pathologies of bones and joints.
- Tumours.
Gives a clear picture of what is happening inside the body and detects pathologies. The procedure is prescribed as a control after ultrasound or CT for confirmationthe established diagnosis. Diagnosis MRI of the brain is the main procedure in the study of an important part of the body.
MRI brain
Tomography of the brain is one of the most important procedures. Since the processes that are embedded in the head are responsible for the entire body. If there is a problem with the brain, then an MRI should be done immediately.
Diagnostic MRI of the brain is a procedure that can be of three types. One of them is to determine the dynamics of blood flow in the section of certain vessels. You can find out how intensely the blood passes. This procedure helps to determine if there are foreign bodies in the vessels that prevent the blood from circulating normally.
Phase contrast imaging involves the injection of a contrast agent that illuminates the vessels. This method helps to see even better what is the cause of the disease for its further elimination.
Four-dimensional study helps to separate arterial blood from venous blood. Thus, it is possible to specifically determine in which part of the head the process of blood supply is disturbed. Angiography of the brain helps to identify the following diseases:
- Aneurysm.
- Atherosclerosis.
- Stenosis.
- Vasculitis, etc.
The computer image shows all the changes that have occurred in the brain tissues. And the contrast agent will easily determine if there is a problem or should be looked for elsewhere.
Spine MRI
To find out the cause of pain in the back area, you needspine diagnostics. MRI of the spinal column and its branches helps to accurately determine the condition of the spine itself, ligaments and muscles of the spinal cord. Shows deformation of tissues and tendons.
This method helps not to guess about the diagnosis, but to get an accurate examination in an hour. The lumbosacral region is responsible for the musculoskeletal system, therefore, is an important study for he althy movement.
No special preparation required, just lie still for accurate scanning of the spine area. The method helps to exclude:
- Spinal hernia.
- Multiple sclerosis.
- Encephalomyelitis.
Displaced discs or pinched nerve should be diagnosed and actively treated to avoid further serious consequences.
Magnetic resonance imaging of the joints
MRI-diagnostics of joints – is the only method that helps to know the condition of these internal tissues. An accurate picture of what is happening can be seen already in the early stages of the disease. And this, in turn, reduces the likelihood of surgical intervention without a confirmed diagnosis. Diagnosis of the knee joint, shoulder, hip and others helps to identify the problem in time and start its immediate treatment. Such diseases lead to disability, so do not underestimate medicine.
Indications for tomography of the joints:
- Bone and soft tissue tumors.
- Fractures.
- Chronic arthritis.
- Injured tendons and nerves.
- Osteoarthritis.
Magnetic resonance imaging of tumors
MRI diagnostics of tumors of different tissues helps to find out the presence of a malignant formation. Tumors can be divided into two types:
- Bone.
- Fabric.
The most common formations on the internal organs. This condition is accompanied by sharp pains at the site of the tumor and increased body temperature, as a reaction to inflammation. There are cases of late diagnosis, when it is necessary to remove the entire organ along with adjacent tissues. But with early diagnosis, this outcome can be avoided. One of the advantages of this method is the ability to see how widespread the disease has spread and begin eradicating it immediately.
Tumours, which are located near the bone tissue, also carry some danger. In the event that such a neoplasm is malignant, additional therapy is prescribed after removal. The MRI method determines the problem, and after that the doctor describes the picture, that is, gives his opinion.
How to prepare for a CT scan
As such, no special training is required. This procedure takes from 20 minutes to an hour and a half and is completely painless. The only point is that you need to follow a special diet when scanning the intestines. The doctor informs about such preparation in advance.
The main thing is to relax and not giveto feel a sense of fear. What is an MRI diagnostic? This is a painless procedure, so there is no reason to worry. Some are frightened by a certain monotony of the movements of the tomograph and the noise that comes from it. But all this is not capable of causing harm. The procedure should be treated as a mandatory measure to improve he alth.
When results are ready
Since all information is recorded on electronic media, then in the future there is a need to print a picture and describe it. For this, the doctor will need some time. But, as a rule, the results of tomography are ready in one or two days. It all depends on the diagnosis and, of course, on the number of visitors.
As a matter of urgency, all information can be dumped onto electronic media and shown to the doctor in this form. There are conditions that are urgent, so the doctor describes the picture as a matter of urgency.
Contraindications to the procedure
Although the procedure is quite effective and can accurately explain the cause of the disease, it has certain contraindications. These include two factors: absolute and relative. Both one and the other do not allow using such diagnostics.
It is strictly forbidden to undergo magnetic resonance imaging for patients who have metal implants or the same kind of fragments in the body. It is necessary to inform the doctor about the presence of such anomalies in the body. It is necessary to clearly understand what an MRI diagnostic is. This is the effect on the body of a magnetic field, anda magnet attracts metal objects to itself, which move and can cause injury to internal organs.
The presence of a pacemaker is also a contraindication to the procedure. Nerve stimulants, claustrophobia, pregnancy make this procedure impossible. In these cases, doctors can offer other research methods that will not affect human he alth.
Reviews about the results of the procedure
What is MRI diagnostics? This is a progressive method of checking your he alth, which makes it possible to protect yourself from serious diseases. Many patients who have undergone such a procedure share their impressions. A method that can replace several diagnostic operations under local anesthesia is MRI diagnostics. Feedback from patients who have undergone gynecological studies suggests that such a procedure does not bring negative sensations, but preserves emotional he alth.
Some patients are very afraid of the procedure itself, but after its completion they admit that not everything is so bad. After all, this method helps to painlessly learn about problems with your he alth. They complain about the noise and the fact that they have to lie on the pull-out bed for a long time. But this is nothing compared to the ability to exclude many diseases.
Magnetic resonance imaging is an effective method for diagnosing the entire human body. The best way to prevent various diseases and fully control chronic ones. It is very important to know if a simple ailment has developed into something more dangerous. If the doctor prescribes such an important study, do not neglect it, he alth is more expensive thanmoney. Nothing is more important for a person than to maintain good he alth, because what you once lose, you will never get back!
