: A total of 62 study subjects have been previously reported. However, the purpose of the previous research was different from this study.Thirty-six subjects were reported in a previous paper (Kang et al Contrast-enhanced US with sulfur hexafluoride and perfluorobutane for the diagnosis of hepatocellular carcinoma in individuals with high risk. Radiology 2020; 297:108–116). That study investigated contrast-enhanced US Liver Imaging Reporting and Data System (LI-RADS) v2017 HCC categorization by comparing perfluorobutane-enhanced US and sulfur hexafluoride–enhanced US in participants at high risk for HCC.Twenty-six subjects were reported in a previous paper (Hwang et al Sonazoid-enhanced ultrasonography: comparison with CT/MRI Liver Imaging Reporting and Data System in patients with suspected hepatocellular carcinoma. Ultrasonography 2021;40:486-498). The aim of that study was to evaluate the association of CEUS features using Sonazoid for liver nodules with LI-RADS categories and to identify the usefulness of Kupffer phase images.
