Scatter plots of the IDSI-derived cellularity compared with Y(tumor/cortex ratio of AMT-SUV) and DWI-ADC values obtained from FLAIR-derived tumor regions of five patients with grade IV gliomas (a), and five patients with grade II gliomas (b). Each plot shows the summation of individual voxels for which DWI-ADC and Y(AMT-SUV ratio) are plotted on the x- and y-axes, respectively, while cellularity values are indicated by color. Note that increased cellularity tends to occur in voxels with low ADC values for all grade IV glioma cases, while there were much fewer voxels with increased cellularity in the grade II gliomas
