EUS-Guided ATI and SWE in Individuals With Normal FibroScan

Starting soon

Conditions studied: Non-hepatobiliary Indications

In brief

The goal of this observational study is to establish preliminary reference values for Endoscopic Ultrasound (EUS)-guided Attenuation Imaging (ATI) and Shear Wave Elastography (SWE) in adults undergoing diagnostic EUS for non-hepatobiliary indications who have normal FibroScan findings. The main questions it aims to answer are: What are the preliminary normal reference values for EUS-guided ATI in the right and left hepatic lobes? What are the preliminary normal reference values for EUS-guided SWE elasticity (kPa) and velocity (m/s) in the right and left hepatic lobes? Participants will: Undergo same-day FibroScan assessment to confirm normal liver stiffness and steatosis parameters. Undergo EUS-guided ATI and SWE measurements of both the right and left hepatic lobes during their clinically indicated diagnostic EUS examination. Have demographic, clinical, and laboratory information recorded for analysis.
