MRI, or magnetic resonance imaging, is a unique, safe diagnostic method. For the first time, the technique was tested on tubes, getting a clear picture. In 2003, the creators of the method received the Nobel Prize. Decoding of MRI is simple, since a clear layered picture of the organ, system being examined is displayed on the crane. Now this diagnostic system is used in almost every clinic. The technique allows you to quickly, clearly and safely for the patient to obtain the maximum amount of data.
What is an MRI? Decryption
Magnetic resonance scanners are huge devices that resemble in shape a circle with a void in the center, or a “donut”. To conduct a diagnostic scan, patients are placed on a special table so that they fit inside the device. Inside the device, patients are fully accommodated: with the head and legs. Then there is a scan of the organ or body part, in which the image is displayed on the screen. Decoding of MRI allows you to quickly and accurately diagnose, because the doctor sees the examined part of the body in several projections: coronal, sagittal and axial. Vessels and various ducts are displayed in a 3D model.
Decoding of MRI allows you to see all the available developmental abnormalities, injuries, pathological foci of the body part and the entire organ under examination. A contrast agent can be used to enhance visualization.
Survey
MRI can be prescribed for pathologies of various parts of the body and organs. This type of diagnostic is used to scan the following areas:
- Heads.
- The neck.
- The spine.
- Joints.
- The internal organs.
- Soft tissue.
- Small pelvis.
Each species has its own characteristics of the diagnostic procedure and preparation for it. So.
MRI of the head
In order. Decoding of MRI allows you to see which parts of the head have developmental abnormalities, as well as where the pathological site is located. This study makes it possible to assess the size of the lesion, the state of blood vessels, joints, endocrine glands.
Decoding MRI of the brain allows you to see if there is a blockage of blood vessels. And also to assess the condition of the pituitary gland, temporomandibular joint, identify hematomas, neoplasms in the brain, see the foci of infection.
MRI of the head is prescribed if patients complain of:
- Noises in the ears that occur at very different times.
- Frequent nosebleeds.
- Migraine, dizziness.
- Violation of sensitivity.
- Decreased concentration, memory impairment.
- Imbalance in movement
Deciphering an MRI of the brain allows you to see what has become the psychological disorders of the patient, and not only. During the examination, the following types of ailments can be revealed in a patient:
- cysts;
- injuries, hematomas;
- abscesses;
- neoplasms;
- blockage of GM vessels, etc.
Decoding MRI of the brain allows you to quickly and accurately diagnose, assess the patient’s health status. The procedure allows the doctor. The reliability of the result is more than 98%. MRI is the only examination method that makes it possible to see hard-to-reach places that cannot be examined using other diagnostic methods.
Abdominal MRI
Most major organs are located in the abdominal cavity. This is the space in which are concentrated:
- liver and gall bladder;
- stomach and pancreas;
- intestines;
- spleen.
An abdominal MRI is done in cases where the doctor cannot make a final diagnosis, and other examination methods are not possible. Or give an incomplete picture of the pathology.
Deciphering the results of MRI most often shows metabolic abnormalities associated with the absence of the enzyme. Also, this type of examination allows you to see inflammatory diseases of the abdominal organs (gastritis, cholecystitis, pancreatitis, hepatitis, etc.). Tomography is performed with or without contrast. The final examination method is selected by a specialist.
Spinal examination
One of the complex systems of the human body is the spinal column. It distinguishes several departments consisting of individual vertebrae.
With pathology, tomography is often prescribed. Usually it is carried out with degenerative-dystrophic ailments, metabolic disorders in bone tissues. MRI is also prescribed for oncological diseases, spinal injuries, developmental abnormalities.
Note. Decoding MRI of the spine allows you to see the lesions in any part of the column, tumor, metastases. The scan builds distinct images of pathological areas in which hernias, inflammations, and developmental abnormalities are visible. Also, this type of diagnosis determines:
- arthritis;
- sclerosis;
- complications after injuries, operations;
- disk breaks;
- squeezing discs of nerve endings;
- displacement, dislocation of the vertebrae;
- spinal stenosis and other types of ailments.
Tomography is a very accurate diagnostic method. Its use allows not only to quickly and correctly establish pathology, but also shows in detail the structure of tissues. The clarity of the picture makes it possible to distinguish on it old scars from new pathological foci.
Larynx examination
Further. Decoding MRI of the larynx allows you to visualize the tissues, their structure, as well as assess the condition of the lymph nodes, blood vessels, and trachea. Pictures help to see even the most minimal changes in the structure of the organ.
Tomography helps to recognize inflammatory areas, neoplasms, laryngitis, to determine the cause of breathing problems. Also, during an MRI, the doctor can assess the condition of the vessels, their patency.
Contraindications
MRI of the head and other parts of the body has contraindications. The examination is not carried out if the patient has a weight of more than two hundred kilograms. Also, it is impossible to apply magnetic resonance imaging to those who have pacemakers and various metal elements in the body. It can be joints, braces, metal crowns, rods in the spine.
Metal elements will not allow to form a clear image on the screen. To avoid this, you must immediately, before the examination, inform the doctor about the availability of such details.
Do not carry out the procedure if:
- the patient cannot hold his breath when diagnosing the abdominal cavity;
- bypass surgery was performed;
- the patient cannot remain motionless for a long time due to pain.
Do not prescribe a procedure for patients suffering from claustrophobia.
Conclusion
MRI is an indispensable diagnostic method that helps to identify a wide variety of pathologies without additional examinations. Just one examination gives the maximum amount of information about the structure of organs and systems, their developmental features. This technology is considered the safest, because of which it can be carried out for children and pregnant women from the second trimester.
