Spikes in Epilepsy: EEG and MRI

Abstract:

I will describe recent work in the area of simultaneous MRI and EEG of inter-ictal discharges associated with Epilepsy.

This work demonstrates that both MR magnitude and phase show large-amplitude changes concurrent with electroencephalography spikes. We found a temporal derivative relationship between MR phase and scalp electroencephalography, suggesting that the MR phase changes may be tightly linked to local cerebral activity. We refer to this manner of MR acquisition, designed explicitly to track the electroencephalography, as encephalographic MRI (eMRI).

This work is a collaborative effort that includes Padmavathi Sundaram, Robert V Mulkern, Ellen J Bubrick, Mirjam Münch, and Darren B Orbach.

Short Bio:

I'm a researcher in medical image analysis with the Surgical Planning Laboratory , a unit of the MRI division of the Radiology Department of Brigham and Women's Hospital. I maintain an active collaboration with the MIT Computer Science and Artificial Intelligence Laboratory, where I work with a talented group of graduate students. I am also affiliated with the Harvard-MIT Division of Health Sciences and Technology , and periodically teach the medical image processing part of HST882 / 6.555: Biomedical Signal and Image Processing .
