Medical imaging in presurgical investigation of epilepsy and new perspectives

In the presurgical epilepsy group, part of the project Vaud-Genève, medical imaging plays an important role in identifying the epileptic focus by means of volumetric measurement of the hippocampi and fusion of high resolution MRI with nuclear imaging PET and SPECT. New approaches are now developing such as functional MR triggered with EEG and MR spectroscopy to restrict the indications of invasive surgical exploration needed when no clear locus is demonstrated by standard medical imaging
