Background
The most common liver cancer in cirrhosis is Hepatocellular Carcinoma (HCC), patients with cirrhosis are also at increased risk for developing intrahepatic cholangiocarcinoma (iCCA) and combined HCC-CCA. Some other malignant lesions may also exist or coexist with HCC. While non-HCC malignancies often occur in patients without cirrhosis, their incidence is increasing in cirrhotic livers.

The American College of Radiology recommends the Liver Imaging Reporting and Data System (LI-RADS) to standardize the reporting and data collection of CEUS, CT-MRI for HCC. LI-RADS-M has specific criteria that allow for the sensitive identification of malignancy. LR-M does not exclude HCC, as some atypical HCC may be categorized as LR-M. However, LR-M more commonly includes non-HCC malignancies.
