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 (ADC_min = 0.55 × 10^− 3 mm²/s). The ADC_mean 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 rCBV_max of 0.76
