Metastasis in a patient with lung adenocarcinoma. T1-weighted image with gadolinium (a) demonstrates a ring-enhancing left parietal lobe mass (long arrow) and a solidly enhancing left frontal lobe mass (short arrow). Extensive vasogenic edema is around each of these lesions (arrowheads). On CBV map (b), the CBV is elevated in the enhancing components (arrows). No increased peri-tumoral enhancement or elevated perfusion is present. ADC map (c) shows minimally decreased ADC in the parietal mass (long arrows) and mildly decreased ADC in the frontal mass (short arrow)
