Hi,
I just had a phone call from The National Hospital of Neurology and Neurosurgery in London, inviting me for the test I have never heard of which is called EEG-fMRI.
I must add that I am quite up to date with Neuroimaging Techniques :).
The purpose of this test is to identify inter-ictal discharges (similar to ictal discharges) but not showing the symptoms of typical seizure, which are a "signature" in the brain that somebody has epilepsy.
There is not much information about this test as the first one has been performed in 1999 but it is still "experimental" and used only for the most complex cases and usually for invasive treatment patients.
Very often it is used before referring for electrocorticography this is invasive test. EEG-fMRI is being used to pinpoint more exact area for the ECoG, and ECoG is being used mostly for surgical patients who have "passed" a series of non-invasive tests, to pinpoint the area which will be removed during the surgery with extremely high accuracy.
Well, wish me luck to stay inside MR device for 3-4 hours ;)
