Figure 5. . Oligodenroglial tumors demonstrate elevated cerebral blood volume.

Figure 5. 

(A & B) Fluid-attenuated inversion recovery hyperintense (left) enhancing 1p19q codeleted ([A] middle) and nonenhancing 1p19q intact ([B] middle) grade 2 oligodendroglioma demonstrates mildly elevated cerebral blood volume when compared with diffuse astrocytoma (Figure 4). Also demonstrated is the tendency for oligodenroglial tumors with the prognostically favorable 1p19q codeleted (A) molecular marker status to express higher cerebral blood volume when compared with tumors with intact 1p19q status. Prior studies have suggested that dynamic susceptibility-weighted contrast-enhanced perfusion MRI may be a noninvasive biomarker of 1p19q genotype.
