Differential diagnosis of an intracranial mass using DSC-MRI. Both patients presented with a peripherally enhancing, centrally necrotic mass (A, E). In Balo concentric sclerosis (upper row), DSC-MRI demonstrates a low rCBV ratio (C) without visible increased perfusion on the rCBV color map (B). Concentric enhancement of the lesion is seen on sagittal post-contrast T1-weighted image (D). In a high-grade glioma (lower row), DSC-MRI demonstrates increased perfusion within the enhancing portions s of the lesion (F) with a high rCBV ratio (G).
