Figure 2

Evaluation criteria for endoscopic ultrasonography (EUS) image quality. (a) Excellent (4 points). Clear images with no debris-like artifacts in EUS. (b) Good (3 points). A few debris-like artifacts are present, but do not interfere with the evaluation of esophageal varices (EVs) in EUS. (c) Moderate (2 points). Debris-like artifacts are noticeable, but do not interfere with EV evaluation in EUS. (d) Poor (1 point). Difficult to assess EV due to debris-like artifacts and poor esophageal lumen expansion in EUS.
