Legend: ↑, increased in HGG compared to metastases; ↓, decreased in HGG compared to metastases; 0, no discernable difference; -, not reported/tested. Bold indicates significance in data, otherwise indicates trends in data. Arrows within parentheses indicate measurement from peritumoral volume, otherwise contrast-enhancing (bulk tumor) volume. Diffusion coefficients listed: FA, fractional anisotropy; MD, mean diffusivity; CL, linear anisotropy; CP, planar anisotropy; and CS, spherical anisotropy.
