A 45-year-old woman with PCNSLs in the white matter. a. Axial T2WI shows the homogeneous high signal intensity on the right centrum semiovale. b. Contrast-enhanced axial T1WI demonstrates a lesion enhancement. c. A corresponding ADC map shows the tumor with a decreased ADC value (ADCmin = 0.55 × 10− 3 mm2/s). The ADCmean value is 0.66 × 10− 3 mm2/s in the left normal white matter. d. A correlative color CBV image shows slightly elevated perfusion with the calculated rCBVmax of 0.76
