In this work, we present an image analysis framework to quantiatively evaluate changes in strucutral, functional, and metabolic markers (obtained via T2-w, DWI, MRS respectively) to (a) identify MRI markers that correlate the most with treatment related changes post-radiation therapy (RT) in prostate cancer (CaP) patients, and (b) compute a weighted MP-MRI map by optimally combining contributions of strucutral (T2-w), functional (DWI), metabolic (MRS) markers, based on their ability to accurately capturing post-RT changes.
