Answer

Diffusion-perfusion MRI has been used to differentiate poorly enhancing lesions.

Tien et al reported that peritumoral edema and nonenhancing tumor have distinguishable features. [10]

The utility of this imaging technique in metastatic diseases is not established, though peritumoral edema is prominent in most cases.
