Temporal lobe epilepsy (TLE) patients that are medically
refractory may be candidates for surgical intervention.
It is critical to select the surgery candidates
confidently to maximize the chance of
post-surgical-seizure freedom. The presence of sclerosis
in hippocampus is a good indicator for a positive
outcome of surgery. This study introduces a novel
approach (Equilibrium-Model) as a grader of sclerosis
severity in hippocampus using MR-Fluid Attenuation
Inversion Recovery (MR-FLAIR) information. The proposed
method is applied on MR-FLAIR information of ten TLE
patients with hippocampal sclerosis (pathology-proven).
Results (80% correct-classification-fraction) imply that
the proposed method may increase confidence in
localizing seizure focus.
