Fig. 4From: Grading of IDH-mutant astrocytoma using diffusion, susceptibility and perfusion-weighted imagingA 43-year-old man with grade 4 IDH-mutant astrocytoma. a. ADC map shows a decreased ADC value in the lesion (ADCmin = 0.916 × 10−3mm2/s). b. SWI shows medium susceptibility signal. c. Post-contrast T1WI shows markedly nodular contrast enhancement. d. rCBV map demonstrates relatively high perfusion with the rCBV value of 4.68Back to article page
