Glial Tumors Electromagnetic Signature Study by MagnetoEncephaloGraphy (MEG) "CONDUCTOME"

Magnetoencephalographic Study of Glial Tumors Electromagnetic Signature

The purpose of this study is to determine the correlation between functional MEG analysis of the tumor and its periphery and the tumor stage and treatment response.

A better tumor grade definition would provide an optimized surgical care, prognosis and therapeutical response evaluation.
