A 38 years-old male patient with a high-grade glioma (GBM, WHO grade IV). T2W EPI at b=0 with the tumor ROI encircled in green (a), and FROC parameter maps of D (b), β (c), and μ (d) with the tumor ROIs indicated by the black contours (see online Figure B for a complete set of images including axial pre-contrast T1W FLAIR (e), post-contrast T1W FLAIR (f), T2W FLAIR (g), and T2W PROPELLER (h) images). Compared to the oligodendroglioma patient in Fig. 1, all three FROC parameters exhibited lower values.
