The first signs of multiple sclerosis diagnosis using MRI
The Role of MRI in multiple sclerosis it is hard to overestimate. This procedure allows to detect malfunctions in brain activity in the initial stages. Magnetic resonance imaging often plays a key role in the formulation of comprehensive diagnosis and further patient treatment.
disease Detection by MRI
In the early stages of sclerosis external, laboratory, and clinical signs may not display any signs, so diagnosis of the disease very problematic. During the medical examination the patient may experience some neurological disorders, loss of sensation, which are the first signs of possible disease. To dispel doubts, to confirm or refute the diagnosis, prescribe such procedure as tomography. MRI (magnetic resonance imaging) can detect pathological processes that occur in the brain and spinal cord, to give a visual picture of the pathological changes of their functions. Using this procedure one can see foci of disease, engendered in the nervous system, to investigate the degree of severity, as well as to distinguish from other possible diseases. The role of MRI in diagnosis of multiple sclerosis the most important in this field of medicine. There is a high accuracy, the effectiveness of this method.
working Principle of MRI: electromagnetic waves have an effect on the body of the patient, and the resulting nuclear resonance character, acting on hydrogen atoms. After irradiation is needed to survey areas of the body, there occurs a change of energy. Then the computer notices the most excited areas, captures and processes them, extracting three-dimensional image of the picture of what is happening on the monitor. The projection is in the form of three volumetric projections.
Ready images given by the imaging, are high the format of the image and better visualize the process of multiple sclerosis. MRI is the yield at statement of the diagnosis difficult, as the use of other methods, for example, laboratory research, will not allow you to fully have an understanding of the processes, visualize the pathological processes and the subtle changes in the brain. When an attending physician makes a diagnosis, first of all, he carefully studies obtained during the procedure pictures. They key point in identifying the disease. The fact that multiple sclerosis is the first signs similar to other diseases. It is very important not to be mistaken with the diagnosis, so resort to the MRI procedure is the right decision.
In recent time very often during the procedure magnetic resonance imaging confirmed the diagnosis of "multiple sclerosis". This is not surprising, since the risk group is increasingly expanding. It includes: people who have had cancer, hereditary predisposition, having complications after surgeries or injuries. Not to be confused with the sclerosis or another disease or complication, MRI performed with a special substance. Before the procedure the patient is administered with a colour pigment that helps to better see the dysfunctions in the brain. Such diagnostics allows to have a more complete picture of the situation of the individual patient and obtained during the study information will help in accurate diagnosis. The use of MRI with a special dye pigment is necessary in difficult situations where accuracy is crucial.
These include sclerosis of the following groups:
- Inflammatory multiple sclerosis, Sjogren's syndrome, lupus erythematosus.
- Sclerosis, accompanied by infectious diseases (Lyme disease, encephalomyelitis).
- Degenerative diseases: myelosis, degeneration.
- vitamin Deficiencies – vitamin B12 deficiency.
- vascular Diseases of the brain and spinal cord.
what are the results?
About the presence of multiple sclerosis speak multiple lesions (called plaques).
Typically, the images are T1 and T2. This pattern accommodates most informative view of the situation. On it you can see the plaques that are most dangerous. Their signal intensity is more pronounced. Each scanning process is responsible for a specific function:
- T1 allows you to see the failure in the functioning of neurons, showing everything that is happening in the form of dark areas on the brain.
- T2 allows you to view the lesions more clearly, to appreciate the complexity of brain disease. This mode has the highest intensity and is used most often.
opinion on the topic
Diagnosis of multiple sclerosis using magnetic resonance imaging, the images are of high quality, will help to notice even the platelets of microscopic size, are not able to identify other methods. It is very important to notice, as the lesions tend to merge, creating a swelling in the size of several centimeters. However, despite the fact that MRI is the most commonly usedmethod of research that exists in medicine, diagnosis is impossible without a full examination of the patient. She also has some contraindications. The procedure can not be performed, if the patient has an implanted pacemaker, artificial joints, the implant in the middle ear, hemostatic clips in the brain. MRI is a powerful method in identifying multiple sclerosis. It allows you to get the most complete picture of the processes, to see the presence of pathologies. Also pictures is an essential element in the appointment treatment, but for it to be most effective, conduct a full examination of the patient.
