What is magnetoencephalography?
Magnetoencephalography (Meg) is a technique of measurement of changes in the magnetic field in the head and around the head created by brain activity. It can be used as an additional evaluation tool together with other studies of brain activity and structure in the patient evaluation process with suspicion of a neurological problem. This technique is non -invasive and patients do not have to take any special steps to prepare for it. The helmet contains superconducting quantum interference (octopus) capable of picking up very weak changes in magnetic fields. The room where the patient goes to the test is protected to ensure that the Earth's magnetic field does not interfere with a very sensitive test. A number of images of brain activity are taken. Gings, showing brain activity and the area of the brain where it comes. This can be very useful when doctors try to isolate brain or lesion damage, which may occur if there are concerns about the function of the brain after an accident or in an epilepsy patient that experiences frequent seizures. This type of studyE can be a useful tool for generating multiple usable data, if there are conflicts between other brain studies, such as magnetic resonance imaging and electroncephalography.
This method of testing works best when a doctor combines it with other testing to create a complete picture of what is happening inside the patient's brain. Magnetoencephalography can be performed on the same day as other brain studies to collect as much information on the patient's brain function and structure as possible. Multiple treatment tests such as treatment can be used to monitor changes or trac.
If a physician recommends a study of magnetoncephalography, patients may ask why the study is recommended, what other testing should consider and how the test will contribute to the development of the diagnosis and treatment plan. One potential use of magnetoencephalography is when creating a very targeted and accurate image of damageIn the brain, so the surgeon knows exactly where to go. Sometimes damaged areas of the brain appear superficially normal when the surgeon works, and have clear instructions to help the surgeon remove the brain lesion without damaging adjacent tissue or leave parts of the lesion behind.
