简要总结
Aim of this prospective national multicenter study is to improve standardization of contrast-enhanced ultrasound (CEUS) in the non-invasive diagnosis of hepatocellular carcinoma (HCC) in high-risk patients.
The study is funded by the German Society for Ultrasound in Medicine (DEGUM).
详细描述
To date, CEUS criteria for non-invasive diagnosis of HCC include arterial phase hyperenhancement, followed by contrast washout in the portal venous or late phase. We would like to investigate the following points:
- whether arterial hyperenhancement alone is sufficient for the definite diagnosis of HCC in cirrhosis with CEUS
- whether a further clearly-defined point of assessment in the late phase after 4-6 minutes is of additional diagnostic value in focal liver lesions showing no contrast washout after 3 minutes
- diagnostic value of CEUS-based standardised diagnostic algorithms (ESCULAP = Erlanger Synopsis of Contrast Enhanced Ultrasound for Liver lesion Assessment in Patients at risk; CEUS LI-RADS = Contrast Enhanced Ultrasound Liver Imaging Reporting and Data System) for non-invasive diagnosis of HCC in high-risk patients (diagnostic accuracy, interobserver-variability, feasability in clinical Routine).
