FIG 4. GBM (grade III/III).
A, T2-weighted image (3158/119/1) demonstrates a left parietal lesion with mass effect, edema, and signal-intensity heterogeneity. These are features of a high-grade glioma, such as a GBM.
B, Contrast-enhanced T1-weighted (600/14/1) with extensive, heterogeneous contrast enhancement.
C, rCBV map shows markedly elevated perfusion.
D, SD25 color map suggests markedly elevated permeability. Note that the areas of highest rCBV elevation do not directly correspond to the regions of highest SD25 (arrow).
