MRI of cervical and thoracic spine: what, how and why?

MRI of the spine MRI of the spine is the diagnosis of the spinal column and its tissues using a magnetic field.

This procedure makes it possible to obtain complete information about the state of the spine.

This is the most effective method of studying the human body.

The essence of the MRI device

Magnetic resonance tomograph is a mobile couch that slowly enters the "tuba" during the study.

The essence of the MRI is that the energy released by the motion of the protons is received by the scanner, broadcast to the computer, then the data is processed and a picture is shown on the screen.

Layered sections of the body are created, and this enables the doctor to correctly assess the state of the body's structures, their pathologies and problems.

Indications for cervical department

Prerequisites for cervical MRI:

  • hearing loss and vision;
  • cervical pain;
  • dizziness;
  • change in blood pressure.

What MRI of the cervical spine shows:

  • osteochondrosis of the cervical vertebrae;mrt of the cervical spine
  • hernia;
  • circulatory disorders in blood vessels;
  • infectious lesion of the spinal cord and bone tissue;
  • spine injury;
  • for suspected tumors and metastases;
  • before operating diagnostics;
  • suspicion of compression of the spinal cord, stenosis;
  • is a demyelinating disease of the nervous system.

MRI of the cervical spine can detect the disease and prescribe the type of treatment( manual therapy, physiotherapy, acupuncture, surgery, laser).

Purpose chest MRT

Symptoms such as chest pain, between the shoulder blades, numbness of the legs and hands, are the first bell to visit the doctor and conduct an MRI scan of the thoracic spine.

Magnetic resonance imaging is prescribed during:

  • infectious lesions;
  • of degenerative - dystrophic diseases;
  • osteomyelitis;
  • for bone tissue tuberculosis;
  • of intervertebral protrusions;
  • oncological tumor and metastasis;
  • abnormal development of vertebrae;
  • Guillain-Bares syndrome, multiple sclerosis.

MRI of the thoracic region, if applied with contrast agents, reveals small cracks and dislocations of the vertebrae, also with the help of it can reveal arthrosis, osteochondrosis, osteoporosis, scoliosis.

Study for problems in the lumbar department of the

For completeness of the picture for problems in the cervical and thoracic spine, MRI of the lumbosacral portion can be prescribed.

It is especially relevant as it is with the manifestation of ordinary inflammatory processes, and with the appearance of tumor formations and dystrophic diseases.

But, it is worth noting that this study is carried out with:

  • acute and chronic pain in the lumbosacral spine;
  • of gross congenital anomalies of skeletal formation;
  • osteochondrosis of the lumbosacral spine;back pain
  • of degenerative-dystrophic cartilage diseases;
  • spondylolisthesis both congenital and acquired;
  • sacralization and lumbarization;
  • pathologies in intervertebral discs - hernia and dorsopathia of the sacral region;
  • traumatic injuries;
  • stenosis;
  • demyelinating diseases;
  • autoimmune diseases;
  • infectious processes affecting the nervous tissue and vertebrae;
  • of osteoporosis;
  • circulatory disorders in the arteries that feed the spinal cord, etc.
Tomography with the introduction of contrast agent, helps to identify tumors and their size, to see metastases. Contrasting is possible for children. Special training does not require.

Contraindications to the procedure

MRI of the spine can not be done in the first three months of pregnancy if there are metal implants( braces, dentures, titanium objects are not considered), during lactation( with contrast agents), with mental disorders( epilepsy).

If the patient's weight exceeds 100 kilograms, the inability to lie still, claustrophobia, a severe stage of decompensation in a chronic disease.

Preparation for the passage of MRI

Before the procedure, it is necessary to remove and remove all products from metal and electronic devices( chains, bracelets, earrings, telephones, clocks, etc.).For such purposes there is a storage room.

If a study is planned with the introduction of a contrast medium, then two hours before it is not advised to eat. It is worth to visit the toilet, so it was easy to lie.

It is also worthwhile to warn the doctor about the presence of pacemakers, pins and metal objects in your body. In such cases, the doctor suggests a different study of MRI, where the whole body is exposed to the magnetic field, but only a part of the body.

Make-up will have to be washed away, in some types of decorative cosmetics, the composition includes impurities of metals.

How the

MRI is undergoing a study. When you visit a clinic, you will be asked to pass a questionnaire. The main task of which is to identify the presence of metal objects in the body.

Then a contract for the provision of paid services is signed. Then the doctor in detail is obliged to tell, how will pass or take place research, and will respond to questions exciting you.

After a brief briefing you will be offered to change into a hospital dressing gown, but you can stay in your own clothes, provided that there are no metal inserts on it.

The procedure itself takes place in a comfortable environment, in a separate room. You are put on a moving couch and fixed with straps to avoid stirring and mistakes in the results of the study.

Give out ear plugs, since the device makes loud noises. The couch slowly moves into the tomography ring, the procedure has begun.

The usual procedure lasts from 20 to 40 minutes, it depends on the area under investigation. At this time the doctor can ask you questions and answer your questions, on a special negotiation device. In addition to a doctor, there is an X-ray lab technician.

If you wish, you may have medical workers or relatives. Inside the scanner works lighting and a fan for your comfort.

After the end of the procedure, you will be taken to the rest room to wait for the results. And you will have to wait 30 minutes to 2 hours, depending on the complexity of the case. When the result is ready, you will receive a DVD with a conclusion and pictures and a detailed transcript of the study.

Decoding of the results

The transcription of the MRI is performed by a qualified radiologist. Explanation of results

Anatomical formations are visualized for radial diagnostics of the spine:

  • hernia of Schmorl;
  • state of intervertebral cracks;
  • displacement of vertebral segments;
  • appearance of osteophytes;
  • the size of the spinal canal;
  • discarding of intervertebral discs;
  • calcium deposition in the ligaments;
  • ossification of soft tissues;
  • tumors of the spine.

What can you understand yourself?

You have received a transcript of the MRI, and naturally you have questions. Unfamiliar figures and terms, how to understand all this?

Better than a specialist, no one will explain this to you. But we will try.

In conclusion, the following notations are definitely encountered: T 1 and T 2:

  1. T 1 is the time during which 63% of the protons return to equilibrium.
  2. T 2 is the time during which 63% of the protons are shifted in phase by the action of neighboring protons. The intensity and contrast of the image often depends on the interval between pulses and the time between the supplied pulse and the emitted signal.

These values ​​measure the height of intervertebral discs, the structure of the spinal cord and the signals coming from it.

With 3-4, With 4-5, With 5-6, With 6-7 is a form of degeneration of a disk, dehydration, decrease in height, extension. This protrusion can be a consequence of lethargic biceps muscles, wrist muscles and neck pain, swelling of the fingers, pain in the upper limbs, headaches.

Diffuse hernia C 5-6 discs( size measured in cm), distorting dural sac, median hernia C 6-7 disc with an anomaly of the frontal contour of the dural space can be detected.

Based on the results of the study, surgery is not required, but an objective opinion of the orthopedist or vertebrologist is needed to prescribe the most effective treatment.

In occasion of the recommendation, on carrying out MRT of vessels of a neck, necessarily consult with the neurologist. Since he can offer an alternative in the form of UZDG vessels of the neck.

UZDG is an ultrasound duplex scan of the vessels of the brain and neck, arteries of the upper extremities and veins of the lower extremities.

Public opinion

MRI of the cervical and thoracic areas Opinions are divided in opinions about the passage of MRI.Someone talks about panic attacks, which are certainly possible.

In case of discomfort, it is worth to inform the specialist who is doing the research. Even if you have not been diagnosed with claustrophobia, everyone can panic.

This is caused by a closed space and a stationary state. But you should not be afraid, if you talk with your doctor during the procedure, you can avoid it. Or choose an open type MRI.

As many people write about loud noise, published tomograph. Some clinics offer to use earplugs, but not everywhere, so, before the procedure, they should be stocked up.

When choosing a clinic, where you are going to do research, it is worth to read reviews about this institution and price policy. There are many clinics, but the quality of the services and the attitude of the staff are different everywhere.

Indoors with a scanner should be comfortable temperature, good light. The doctor and radiologist should, if necessary, talk with you.

But basically, with this procedure, everyone is happy, as it is, the most informative in the study of the human body. If necessary and the appointment of a doctor tomography, it is worth it to go, in spite of minor shortcomings.

Cost of the

study Today in Moscow there are at least 165 clinics that make MRI of the spine. There are 86 clinics in St. Petersburg. MRI examination

Average price of MRI of the spine all over Russia:

  • of one spine department from 2500 rub.up to 9000 rubles;
  • three departments of the spine and coccyx from 6000 rub.up to 10,000 rubles.

The pricing policy depends on the type of scanner, the specialist who conducted the study, whether the contrast medium is used, and from the region.
