Figure 3. ROC curves for all the metrics in differentiating tumor grades.

Figure 3

ROC curves and AUCs for all the metrics in the solid region of the tumor for the differentiation a. between HGGs and LGGs, b. between grade II and III and c. between grade III and IV gliomas. ROC curves: receiver operating characteristic curves; AUC: area under the curve; MK: mean kurtosis; Ka: axial kurtosis; Kr: radial kurtosis; MD: mean diffusivity; FA: fractional anisotropy; ADC: apparent diffusion coefficient; HGGs: high-grade gliomas; LGGs: low-grade gliomas.
