Fig. 2From: Grading of IDH-mutant astrocytoma using diffusion, susceptibility and perfusion-weighted imagingA 40-year-old man with grade 2 IDH-mutant astrocytoma. a. ADC map shows an increased ADC value in the lesion (ADCmin = 1.645 × 10−3mm2/s). b. SWI map shows no susceptibility signals. c. Post-contrast T1WI shows a nonenhancing lesion. d. rCBV map shows relatively low the rCBVmax value (0.76)Back to article page
