Glioma grade as a function of tumor size and time in comparison to [3] results. Tumor grade as a function of tumor size and time in comparison to results of [3] for two different diffusion-proliferation pairs. (a) corresponds to a primary glioblastoma produced by D=0.01 m m²/d a y, ρ=0.033/d a y, (b) illustrates a secondary (progressive from lower grade) glioblastoma produced by D=0.06 m m²/d a y, ρ=0.013/d a y. The dotted curves correspond to comparative results of [3]. Yellow part: minimum T2 detectable radius, blue part: grade II radius, green part: grade III radius, red part: grade IV radius.
