Figure 2

Relative cerebral blood volume (rCBV) imaging heat-map of 73 treatment-naive patients with low-grade diffuse and anaplastic gliomas.
The color of the voxel corresponds to the relative number of rCBV-voxels in each cluster and goes from white (low frequency) to purple (high frequency). Overall, IDH-1/2 wild-type tumors (top of the heat-map) clustered at a significantly higher rCBV as compared to IDH-1/2 mutant tumors (bottom of the heat-map) (see Table 2 for statistical results).
