A 52-year-old man with a primary central nervous system lymphoma in the cortical gray matter. a. Axial T2WI demonstrates the heterogeneous high signal intensity on the right temporal lobe. b. Contrast-enhanced axial T1WI demonstrates a lesion enhancement. c. A corresponding ADC map shows the tumor with a decreased ADC value (ADCmin = 0.56 × 10− 3 mm2/s). The ADCmean value is 0.68 × 10− 3 mm2/s in the left normal cortical gray matter. d. A correlative color CBV image shows highly elevated perfusion with the calculated rCBVmax of 3.42
