Diffusion-weighted magnetic resonance imaging and micro-RNA in the diagnosis of hepatic fibrosis in chronic hepatitis C virus

Figure 2 Receiver operating characteristic curve of patients vs controls. A: The cut-off apparent diffusion coefficient value used for differentiating patients from controls is 1.83 × 10^-3 mm²/s with an area under the curve of 0.992, sensitivity of 98.6%, and accuracy of 97.1%; B: The combination of apparent diffusion coefficient and miR-200b used for differentiating patients from controls shows an area under the curve of 0.995, sensitivity of 100%, and specificity of 96.9%.
