Figure 2

Images obtained in a 44-year-old man with astrocytoma (isocitrate dehydrogenase 1 [IDH1] mutant glioma). (A) Fluid-attenuated inversion recovery (FLAIR) image shows a heterogeneous hyperintense lesion in the right frontal lobe. (B) Apparent diffusion coefficient (ADC)0,1000 map shows increased ADC value in the lesion. (C, D) Intravoxel incoherent motion (IVIM) perfusion fraction (f) and simplified perfusion fraction (SPF) maps show no increased values in the corresponding area of the hyperintense lesion as shown in (A). (E) On contrast-enhanced T1-weighted image, the lesion is non-enhancing. (F–H) Dynamic contrast-enhanced (DCE) MRI parametric maps of volume transfer constant (Ktrans), extravascular extracellular volume fraction (ve) and vascular plasma volume fraction (vp) show no increased values in the lesion. Regions of interest are marked on parametric maps.

Figure 3

Images obtained in a 72-year-old woman with astrocytoma (isocitrate dehydrogenase 1 [IDH1] wildtype glioma). (A) FLAIR shows a heterogeneous hyperintense lesion in the right hemisphere. (B) Apparent diffusion coefficient (ADC)0,1000 map shows a mixed pattern of high and intermediate ADC values in the lesion. (C, D) Intravoxel incoherent motion (IVIM) perfusion fraction (f) and simplified perfusion fraction (SPF) maps show markedly increased f and SPF values in the corresponding area of the contrast-enhanced lesion as shown in (E). (E) On contrast-enhanced T1-weighted image, the lesion is vividly enhanced. (F–H) Dynamic contrast-enhanced (DCE) MRI parametric maps of volume transfer constant (Ktrans), extravascular extracellular volume fraction (ve) and vascular plasma volume fraction (vp) show obviously increased values in the corresponding area of the contrast-enhanced lesion. Regions of interest are marked on parametric maps.

Receiver operating characteristic (ROC) curves and corresponding area under the curve values for (A) diffusion-weighted imaging (DWI) parameters (simplified perfusion fraction [SPF], perfusion fraction [f], apparent diffusion coefficient [ADC]0,1000) and (B) dynamic contrast-enhanced (DCE) MRI parameters (transfer constant [Ktrans], extravascular extracellular volume fraction [ve] and vascular plasma volume fraction [vp]) in the differentiation of isocitrate dehydrogenase 1 (IDH1) mutant and wildtype gliomas. SPF showed the highest diagnostic performance with the area under the curve value of 0.86.
