Li F, et al. - The diagnostic performance of contrast-enhanced ultrasound (CEUS) in differentiating combined hepatocellular cholangiocarcinomas (CHCs) from hepatocellular carcinomas (HCCs) and intrahepatic cholangiocarcinomas (ICCs) was assessed in this study. The outcome suggests that CEUS could be utilized in the differential diagnosis of CHC from HCC and ICC, although the imaging features of CHC, HCC, and ICC on CEUS may overlap.
