Magnetic resonance imaging is quite deservedly considered one of the most informative types of research. On the MRI of the head and blood vessels of the brain, even the slightest changes can be seen. The procedure is absolutely painless and bloodless.
Indications for MRI of cerebral vessels
During the procedure of magnetic resonance imaging, powerful magnetic fields and high-frequency pulses are used. They allow you to get a detailed description of the state of organs and tissues and bring it to the computer. Special programs make it possible to decipher the information obtained on the development of vessels, the presence of constrictions or enlargements in them, as well as changes that have occurred in the brain.
MRI and angiography of cerebral vessels are shown with:
- suspicions of a brain tumor;
- stroke ;
- frequent seizures;
- heart rate malfunction;
- abrupt and progressive deterioration of memory;
- injuries;
- regular dizziness;
- diseases of the pituitary gland;
- mental disorders;
- rapid fatigue;
- irritability;
- violations of coordination of movements ;
- diseases of the inner ear;
- the appearance of weakness in the limbs.
MRI of the head and blood vessels of the brain can also detect inflammatory processes occurring in the ears, nose, and maxillary sinuses. After all, the root of all the above problems is not always hidden in the brain.
How is MRI of the brain vessels performed?
Magnetic resonance imaging lasts no more than half an hour. During the procedure, a nurse can ask the patient to change into a loose natural shirt, remove jewelry and metal objects. A special diet before tomography is not to be adhered to. Do not have to change for the procedure and the usual rhythm of life. The only inconvenience - before tomography will need to pass a number of tests.
Since in some cases during an MRI requires the study of cerebral vessels with contrast, doctors are required to find out if the patient is suffering from allergies. In addition, specialists will need to talk about all the associated diseases, the transferred operations, the characteristics of the body.
For the time of tomography, the patient is placed on a movable couch. Special devices and sensors are mounted on its head, capable of receiving and transmitting radio waves. After this, the couch is placed in a special chamber, where the research is carried out.
