What is MEG and what makes CTF MEGTM the most advanced MEG technology in the world?
Magnetoencephalography (MEG) is a revolutionary medical imaging technology that provides
unprecedented insight into the workings of the human brain through the measurement of
electromagnetic activity.
By measuring the magnetic fields created by the electric current flowing within the neurons,
MEG identifies brain activity associated with various human brain functions in real time, with
millimeter spatial accuracy.
This non-invasive approach can positively impact patient outcomes, providing clinicians
with the invaluable information needed to evaluate neurological disorders and plan surgical
treatments.
In addition to the powerful CTF MEGTM cMEG (cortical MEG) system, the unique non-invasive nature of
the CTF MEGTM fMEG (fetal MEG) system provides researchers an unprecedented opportunity to study
the early development of the human brain.
Investing in the CTF MEGTM fMEG enables research organizations to engage in this exciting and
pioneering area of scientific discovery.
MEG - Unprecedented Insight Into the Workings of the Human Brain
- Completely non-invasive procedure (no radiation dose).
- Real-time, functional view of brain activity with high temporal and spatial resolution.
- Magnetic measurements encounter no distortion from fluid, skin or bone enabling significant localization improvement over EEG.
- Rapid preparation of patients and subjects.
- No disturbance in magnetic environment unlike MRI.
- Investigation possible in both seated and supine positions.
- Provides clinicians with precise localization of brain function when evaluating neurological disorders and planning surgical treatments.
- Valuable insight for improved patient outcomes.
MEG applications:
- Pre-surgical Functional Mapping: Prior to any neurosurgical intervention, MEG can be used to non-invasively identify eloquent cortex (the regions of the brain responsible for motor, sensory, and language function), minimizing the possibility of post-surgical functional deficit.
- Epileptic Foci Localization: Of the 50 million epilepsy patients worldwide, approximately 30 - 40% are refractory to anti-convulsant medications. For patients who suffer from drug refractory seizures, the surgical removal of epileptogenic tissue may be the only way to effectively treat the condition. MEG provides a proven rapid non-invasive method of localizing the epileptic activity with great precision and accuracy.
- Applications under research: Ongoing research has shown that MEG may
assist in the diagnosis and treatment of traumatic brain injury, development dyslexia,
Alzheimer's disease, stroke rehabilitation, autism, Parkinson's disease, Multiple Sclerosis,
schizophrenia, and cognitive and mental disorders.
Further, the unique CTF MEGTM fMEG system is the only instrument capable of providing researchers a capability to non-invasively observe the early development of human brain function.
The CTF MEGTM Advantage
The quality of an MEG system is principally defined by its ability to detect brain signal and reject
environmental noise. Only CTF MEGTM instruments employ a patented method of synthetically constructing higher
order gradiometers which are extremely effective at rejecting magnetic noise outside the brain region.
This method does not require the operator to characterize noise in the local environment or to re-tune the system.
In either optimal or challenging magnetic environments the low-noise and stable performance of
the CTF MEGTM is unsurpassed.
