A METHOD FOR IMAGING OF INTRACRANIAL EEG ELECTRODES USING MAGNETIC-RESONANCE-IMAGING

In this study, we describe a method for imaging intracerebral electrodes within a three-dimensional reconstructed image of the brain. A three-dimensional image of the brain was reconstructed from serial magnetic resonance images. The locations of intracerebral electrodes were determined from anterior-posterior and lateral skull X-rays performed after intracerebral electrode implantation. The three-dimensional reconstruction of the brain including electrode locations was displayed using IRIS Explorer Software (Silicon Graphics, Mountainview, CA). This method might improve the interpretation of electrical patterns of seizure activity recorded from intracerebral electrodes. (C) 1994 Academic Press, Inc.
