ROC curve analysis of CT-PI parameters and ADC value for evaluating the efficacy of TACE combine with CT-guided RFA for HCC. (A) HBF, HBV, PS, HAP, and HPI; (B) MTT, PVP, and AFP; and (C) ADC value of MR-DWI. ADC = apparent diffusion coefficient, CT-PI = CT perfusion imaging, HAP = hepatic arterial perfusion, HBF = hepatic blood flow, HBV = hepatic blood volume, HCC = hepatocellular carcinoma, HPI = hepatic perfusion index, MR-DWI = diffusion weighted magnetic resonance imaging, MTT = mean transit time, PS = permeability surface, PVP = portal vein perfusion, RFA = radiofrequency ablation, ROC = receiver-operating characteristics.
