PET images (upper panel) for lower grade glioma (IDH1-mutant diffuse astrocytoma) (patient no. 3 in Table 2) (a), higher grade glioma (IDH1-wildtype anaplastic astrocytoma) (patient no. 8 in Table 2) (b), and glioblastoma (patient no. 21 in Table 2) (c) and corresponding histograms for pixel count and logscale pixel number above the threshold as a function of pixel value (kBq/mL) in the tumor area (lower panel). The shaded area represents the numbers of pixels above thresholds, and the obtained number are plotted as the pixel number. The dashed line shows upper and lower limits for fractal analysis. The slope of the line on the points plotted indicates the fractal dimension
