Evaluation of gliomas peritumoral diffusion and prediction of IDH1 mutation by IVIM-DWI

ROC curves of parameters derived from IVIM-DWI between group IDH1mut and IDH1wt. (A) ROC of CBF1 in differentiating IDH1mut and IDH1wt; (B) ROC of CBF2 in differentiating IDH1mut and IDH1wt; (C) ROC of CBF3 in differentiating IDH1mut and IDH1wt; (D) ROC of rCBF1-2 in differentiating IDH1mut and IDH1wt; (E) ROC of rCBF3-2 in differentiating IDH1mut and IDH1wt; (F) ROC of D1 in differentiating IDH1mut and IDH1wt. (cerebral blood flow: CBF; the CBF of tumor parenchyma areas: CBF1; the CBF of mirror side normal areas: CBF2; the CBF of peritumoral areas: CBF3; rCBF1-2= CBF1/CBF2; rCBF3-2= CBF3/CBF2).
