We present a quantitative image analysis framework which enables high-resolution evaluation of treatment-related changes in vivo for patients undergoing laser interstitial thermal therapy (LITT). Our computerized decision support framework brings different MP-MRI parameters into alignment and differentially weights their contributions for treatment evaluation. Preliminary results suggest that our framework can accurately quantify changes in MP MRI imaging markers. The integrated MP-MRI difference map showed excellent utility in quantifying the extent and types of focal treatment-related changes, in vivo.
