Receiver-operating characteristic (ROC) curve analysis of the cross-sectional liver imaging and serum markers for patients with intrahepatic lithiasis underwent hepatectomy. (A) Enhanced CT, enhanced MRI, Ultrasonography, comprehensive imaging diagnosis, nonenhanced MRI, and nonenhanced CT. (B) Serum CEA. The cutoff and the optimal cutoff values of serum CEA (µg/L) were used to determine the sensitivity and the specificity of the intrahepatic cholangiocarcinoma (ICC) diagnosis. (C) CA 19-9. The cutoff and the optimal cutoff values of serum CA 19-9 (U/mL) were used to determine the sensitivity and the specificity of the ICC diagnosis.
