Fig. 1B —Scatterplots of relative ductal enhancement. Scatterplots show relative ductal enhancement in portal venous phase (PVP) (A) and ductal wall thickness (B) in cholangiocarcinoma and periductal fibrosis groups. Optimal cutoff values were 10 H and 2.8 mm, respectively. Sensitivity and specificity were 71.4% and 81.2%, respectively, at 10 H and 71.4% and 75.0% at 2.8 mm.
