Anyone have a MEG?

[Eyes_herself]

I went to my neurologist today and he suggested me getting a MEG. I am really unfamiliar w/ the procedure and find some sources not so 'potential patient' satisfying. Has anyone had one? Any tips as to whether they would do it again? Results?

The full name for MEG is Magnetoencephalography.

I hope these help. It is a new one to me.

From BuckEyeFan's link:

Focal Epilepsy

The clinical uses of MEG are in detecting and localizing epileptiform spiking activity in patients with epilepsy, and in localizing eloquent cortex for surgical planning in patients with brain tumors or intractable epilepsy. The goal of epilepsy surgery is to remove the epileptogenic tissue while sparing essential brain areas to avoid neurologic deficits [11]. Knowing the exact position of essential brain regions (such as the primary motor cortex and primary sensory cortex, visual cortex, and speech cortex) is of utmost importance. Direct cortical stimulation and somatosensory evoked potentials recorded on ECoG are considered the gold standard for localization of essential brain regions. These procedures can be performed either intraoperatively or from chronically indwelling subdural grid electrodes; however, they are both invasive to the patient. MEG localizations of the central sulcus obtained from somatosensory evoked magnetic fields show strong agreement with these invasive recordings [12][13][14]. MEG studies assist in clarification of the functional organization of primary somatosensory cortex and to delineate the spatial extent of hand somatosensory cortex by stimulation of the individual digits. This agreement between invasive measures of localization of cortical tissue and MEG recordings implies the effectiveness of MEG analysis.

Looks like it's used to help identify potential areas for brain surgery.

MEG is also a part of the fMRI in Radiology.
I have someone here that's heading to
Birmingham to have one done.

I'll let you know of the person's results when
they get back after a few weeks.
