Contrast (Sonazoid)-Enhanced US as a Screening Tool for Hepatocellular Carcinoma in Cirrhosis: An Exploratory Cross-sectional Study
- Conditions
- Hepatocellular Carcinoma (HCC)
- Interventions
- Other: Sonazoid-enhanced ultrasonography
- Registration Number
- NCT02188901
- Lead Sponsor
- Yonsei University
- Brief Summary
B-mode ultrasonography (B-US), a standard method of surveillance of hepatocellular carcinoma (HCC), has a fair sensitivity of 63% in detecting early stage HCC. Sonazoid, a contrast agent for ultrasonography, has reported to have superior sensitivity in detecting focal liver lesion since it has ability of Kupffer phase imaging as well as vascular phase imaging. So our aim is to compare the detection rate of early stage HCC and false referral rate of HCC between B-mode US and Sonazoid-enhanced ultrasonography (S-US) within the same prospective data group. Our hypothesis is that S-US has superior detection rate of early stage HCC (5%) than that of B-mode US (3%).

- Primary Outcome Measures
Name Time Method Detection rate of early stage HCC 30±30 days after S-US if there is one or more suspicious HCC detected on S-US, or 180±30 days after S-US if there is no suspicious HCC detected on S-US Detection rate of early-stage HCC = (Number of confirmed early-stage HCC detected by a given modality) / (Total number of patients enrolled) x100
False referral rate of HCC 30±30 days after S-US if there is one or more suspicious HCC detected on S-US, or 180±30 days after S-US if there is no suspicious HCC detected on S-US False referral rate of HCC =
