In this work, we quantitatively evaluate changes in multi parametric MRI (MP-MRI) imaging markers (T1-w, T2-w, T2-GRE, T2-FLAIR, and ADC) over the epileptogenic foci, pre- and post- laser interstitial thermal therapy (LITT), to (a) identify MR imaging markers that change most-dramatically over time while computing treatment related changes post-LITT, and (b) develop a weighted temporal MP-MRI signature corresponding to successful / unsuccessful treatment, by combining the imaging markers identified as most contributory in evaluating treatment related changes at different time points post-LITT, in a cohort of epilepsy patients.
