MRI diagnosis - what is it? Purpose, Benefits and Contraindications

MRI (Magnetic Resonance Imaging) is used in many areas of medicine.

This diagnostic method is a relatively safe and informative way to study various pathologies. Consider what this study represents and when it is used.


What is MRI diagnosis?

MRI diagnostics is a non-invasive (without internal intervention) research method that provides information on the condition and structure of human internal organs.

The diagnostic method is based on the measurement of electromagnetic fields from different organs and tissues in the human body. This information is analyzed by the computer and gives the result, which evaluates the specialist.

MRI diagnostic device

Thanks to modern equipment, it is possible to obtain a three-dimensional model of internal structures. This method has found wide application in modern medicine, especially in cases where invasive examination methods are contraindicated for the patient.

When is prescribed by an MRI doctor?

Diagnostics is not related to ionizing radiation and is relatively safe for the patient.

In some cases, MRI is used using contrast media to obtain a clear, detailed image. In such cases, the risk of allergic reactions.

The study can be performed on your own or a specialist directs it if you suspect a tumor, aneurysm, trauma, diseases of the spine and other problems, depending on the patient's complaints.

What diseases can be detected by MRI?

There are several types of research that allow the doctor to clarify the diagnosis:

1. MRI of the brain. It makes it possible to identify tumors, the state of the optic and auditory nerves, as well as identify problems with the vessels and the presence of aneurysms.

2. MRI of the spine. Used to identify the causes of obscure pain, as well as after injuries.

Diagnosis not only gives information about the state of the intervertebral discs, the presence of hernias and tumors in this area, but also allows you to investigate the flow rate of the spinal fluid and learn about problems with blood supply in the area.

3. MRI of the joints. Allows you to diagnose old injuries and deformities of the joints, to identify features of adhesions of fractures, to clarify the structure of the bone and the presence of tumors.

4. MRI of the abdominal cavity. It makes it possible to visualize parenchymal organs, the location and size of the lymph nodes, the state of the vessels.

Used to diagnose the tumor process, clarify its prevalence and control after antitumor treatment.

This method is not informative in the diagnosis of intestinal diseases, as well as in urolithiasis and some other pathologies due to the fact that certain structures are not visualized in this study.

Benefits of MRI diagnostics in medicine

Benefits of MRI Diagnostics

brain analysis

MRI in medicine is mainly used to diagnose the pathology of soft tissues. The method is widely used in oncology, diagnosis of pathology of the spine and brain, angiology and other areas of medicine.

Key benefits are:

  • lack of radiation exposure in contrast to CT;
  • a highly informative method for diagnosing tumors in the early stages;
  • You can get a high-quality image without the use of contrast;
  • allows you to specify not only the structure, but also some functional parameters (speed of flow of cerebrospinal fluid, activation of the cerebral cortex, blood flow velocity, etc.).

Important! This method is practically not used in the diagnosis of pathology of the lungs, stomach, bones and intestines.

In most cases, special preparation for the diagnosis is not required except for an abdominal MRI.

Before the procedure, the patient is asked to remove all metal objects (buttons, jewelry, etc.), since they may affect the quality and results of the study.

The patient is invited to the room for MRI studies, where he lies in a special tube. There are devices where the patient can stand during the study, but they are inferior in image quality.

Throughout the study, the specialist observes the patient using video equipment. If necessary, you can talk to the doctor using the intercom.

The main requirement is the maximum immobility of the patient - this is important for obtaining the highest quality image. The whole process lasts a relatively short time of 20-30 minutes.

If necessary, a contrast is administered to the patient before the examination in order to more accurately examine the areas of interest.

During the examination the patient may be disturbed by the noise of the device, which is normal for the operation of the device. To the noise did not deliver discomfort, you can use special headphones.

The problem may be a narrow, closed space, frightening people suffering from claustrophobia. In newborns and children, short-term anesthesia is often used during the study, as it is difficult for small patients to remain immobile for so long.

Light sedatives can also be recommended for adults who have had negative experiences with such examinations.

Contraindications MRI diagnosis

Contraindications MRI diagnosis Despite the relative safety of the study, there are a number of contraindications for its conduct:

  1. The presence of a pacemaker in a patient.
  2. Some types of implants in the middle ear.
  3. Metal plates, fragments or Ilizarov apparatus.
  4. The first trimester of pregnancy, because there is no proven data on the effect of magnetic fields on the formation of the fetus.
  5. Mentally unstable patients.
  6. Patients in coma or with concomitant severe diseases in the stage of decompensation.
  7. The presence of tattoos, which include dyes based on metal compounds.
  8. Some others.

If contrast is used in MRI, an allergy to contrast, pregnancy and severe renal failure is added to the list of contraindications.

The use of MRI greatly expanded the possibilities of medicine. This effective and relatively safe method is used in both adults and children.

To obtain a quality result, you need to follow all the recommendations of the doctor during the study.

Results should be analyzed by a specialist taking into account the history and data from other clinical studies.
