Median values based on tumor delineations from one radiologist and intraclass correlation coefficients (ICC) between the two radiologists. f = perfusion fraction, D * = pseudodiffusion coefficient, D = diffusion coefficient, BF = relative blood flow, AUC 30/AUC 60 = area under curve for 30 and 60 seconds, respectively, after bolus arrival (a. u. = arbitrary units), K trans = transfer constant between blood plasma and the interstitial space, k ep = rate constant, v p = blood plasma volume, v e = extracellular, extravascular space.
