Figure 5From: The role of diffusion and perfusion weighted imaging in the differential diagnosis of cerebral tumors: a review and future perspectivesIntracranial lung metastasis in a 68Â year-old-man. a) T2-weighted image, b) ring-shaped enhancement on a T1-weighted post contrast edema, c) restricted diffusion in the periphery of the tumor. Increased intratumoral ADC (d), decreased FA (e) and elevated perfusion in the peripheral solid part of the lesion (f).Back to article page
