The Role of Dynamic Susceptibility Contrast-Enhanced Perfusion MR Imaging in Differentiating between Infectious and Neoplastic Focal Brain Lesions: Results from a Cohort of 100 Consecutive Patients

Examples of rCBV maps of neoplastic and infectious lesions.
Glioblastoma multiforme in a 49-year-old man (A,B,C). Axial FLAIR image shows a mass lesion in the right parietal lobe surrounded by infiltrating and vasogenic edema (A), with irregular peripheral enhancement on axial contrast-enhanced T1-W image (B) and increased vascularity on the color-coded rCBV map (C). Metastatic melanoma in an 18-year-old man (D,E,F). Axial FLAIR image depicts a mass lesion in the left parietal lobe with perilesional vasogenic edema (D), irregular peripheral rim enhancement on the axial post-contrast T1-W image (E) and increased vascularity on the color-coded rCBV map (F). Cerebral toxoplasmosis in a 54-year-old woman (G,H,I). Axial FLAIR image shows a mass lesion in the left parietal lobe with surrounding vasogenic edema (G), irregular peripheral rim enhancement on the axial post-contrast T1-W image (H) and hypovascularity on the color-coded rCBV map (I).
