About this trial
The goal of EPI-CATCHER is to outline the clinical potential of multiparametric quantitative MRI (mqMRI) and of GABA-edited magnetic resonance spectroscopy (GABA-MRS), combined with machine learning tools, as imaging biomarkers to localize and delineate the EZ.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Patient group
Patients aged 18-65 years,
Patients with drug-resistant focal epilepsy,
Patients with MTLE suspicion, with normal MRI or hippocampal sclerosis, and candidate for surgery,

Trial outcomes
Primary outcomes
EZmri vs EZsdt
The correlation coefficient between the Dice similarity coefficient (= 2 \* the Area of Overlap between EZMRI and EZsdt divided by the total number of pixels in EZMRI and EZsdt) and the reduction in seizure frequency (= seizure frequency one year after surgery / seizure frequency at inclusion).
Secondary outcomes
mqMRI : T1 (ms)
Compare, for each patient, the mqMRI parameter values measured in the EZsdt with the mean mqMRI parameter values obtained in the same region across the healthy volunteers
mqMRI : T2 (ms)
Compare, for each patient, the mqMRI parameter values measured in the EZsdt with the mean mqMRI parameter values obtained in the same region across the healthy volunteers
mqMRI : Mean Diffusivity (s/mm²)
Compare, for each patient, the mqMRI parameter values measured in the EZsdt with the mean mqMRI parameter values obtained in the same region across the healthy volunteers
mqMRI : Cerebral Blood Volume (%)
Compare, for each patient, the mqMRI parameter values measured in the EZsdt with the mean mqMRI parameter values obtained in the same region across the healthy volunteers
