How is it performed and what does the MRI of the elbow joint show?
MRI is a tomographic method for examining internal organs, tissues, joints with the help of the physical phenomenon of nuclear magnetic resonance.
Was founded in 1973 by Professor Paul Lotober. A little later, Peter Mansfield perfected the mathematical model of image acquisition.
Since then, the method used to diagnose various diseases has virtually no contraindications and negative effects on the human body.
With MRI it is possible to visualize the head, spinal cord, internal organs, joints, tendons, muscles, the presence of synovial fluid with high accuracy, determine the level of diffusion in tissues, etc.
All received information is recorded on a special medium or printed out as pictures for further study by the attending physician and the appointment of adequate treatment.

Elbow joint examination
MRI of the elbow joint is a modern, accurate and safe method for determining degenerative changes, injuries,fractures, infections, tumors.
It is carried out both platno, and in a direction of the attending physician. The latter is performed only in the presence of a serious, rapidly progressing disease or hospitalization of the patient.
Indications for research
Magnetic resonance imaging of the elbow is recommended in the following cases:
- fractures and bruises;
- restriction of movement in the joint and pain;
- bone pain, accompanied by fever;
- persistent pain, not amenable to "local" treatment or cupping;
- inaccurate results obtained with CT or X-ray;
- redness or swelling;
- the presence of a tumor or bulk mass that does not dissolve for a long time or increases in size;
- cancer of the elbow joint;
- are other, less common diseases.
What is seen on the MRI?
MRI of the elbow allows you to see the condition of internal tissues, cartilage, bones, synovial membranes.
If there are certain symptoms, determine the severity and extent of the disease, which is of great importance in the treatment and further perspective.
Study allows you to see:
- arthritis, arthrosis;
- nerve damage;
- presence of infections;
- inflammation of synovial membranes;
- ganglionic cyst;
- various damages of muscles, ligaments, tendons.
Preparing for the
procedure It is necessary to make an appointment for the examination in advance. Allocate two to three hours of free time. Eating does not matter. But if the procedure is carried out with contrast, then the last reception should be in a few hours.
Before the examination it is necessary to undress to the waist in a special booth. Remove all metal objects. There you can leave personal things. It is locked with a key. There is also a special gown, which is worn on top.
When you are ready you will be invited to the examination room.
The area under investigation is immobilized with special tools. If the room is cool, then you will cover with a cloak. During the examination, you can not move.
The procedure takes from five to twenty minutes .In some cases, up to an hour. When using contrast, the examination time increases.
For tomography examination of small children, light anesthesia is used. It is difficult for them to remain motionless. The slightest displacement of the surveyed area can lead to inaccuracy in the results and the procedure will have to be repeated.
Study with contrast agent
When using a contrast agent, the clarity of the obtained data increases.
In addition, the contrast allows you to trace the blood supply to nearby tissues. In other words, it accumulates and "highlights" the investigated areas. As a result, the roentgenologist is easier to put the correct diagnosis.
The composition uses gadolinium based on which the following contrasts are made:
- a magnevist;
Contrast is not necessary and is prescribed by your doctor. But if you are doing an MRI on your own initiative, then it is better to take this opportunity.
Side effects of the use of contrast agent
Rarely, nausea, numbness at the injection site is noted. Deaths, poisoning or allergic reactions in practice are not recorded.
Contraindications to the procedure
Do not conduct MRI to pregnant women, people who have tattoos using metal-containing dyes, insulin pumps, heart failure, prosthetic heart valves.
Categorically contraindicated for people with metal plates after fractures, with implants, ferromagnetic fragments, pacemakers, hemostatic clipping of the brain.
People prone to claustrophobia can be shown sedatives to relieve anxiety. In the acute form of claustrophobia, the procedure is performed on an open-type apparatus.
The tomograph works quietly, however, if you are uncomfortable with the sound being produced, ask for special headphones or earplugs.
Where to conduct research in Russia
In Moscow and throughout Russia, an elbow joint MRI can be made in any hospital with appropriate equipment. It can be found on the website or by calling the medical institution.
In addition, there are now many private clinics that also offer this type of service. In the latter case, the price for a tomography can be much higher.
The approximate cost of the procedure is from 3 000 to 10 000 rubles .In small towns, the price can be significantly lower - it depends on the area under study, the medical institution, the course and nature of the disease, the use of the contrast agent, the psychophysical condition of the patient, the equipment( obsolete or modern).
In any case, it is necessary to call several institutions in advance in order to choose the optimal cost. If possible, sign up for a preliminary consultation.
To date, the MRI is the most accurate research method for , which helps to determine the disease and its possible causes. Under the supervision of a qualified specialist, choose the right and adequate treatment.
MRI does not have harmful radiation as a CT or X-ray. Absolutely safe for humans. The same applies to the contrasting substance. The procedure can be performed several times in a certain period of time.
