About this study

The purpose of this study is to assess the combined impact of post-processing methods that quantify potential biomarkers of chronic liver disease (AEF, fECS) and that improve iodine signal (vMono+) on detecting liver fibrosis and hepatic masses or esophageal varices, in comparison to routine contrast-enhanced liver CT.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
