Figure 1
Representative EUS images for evaluating EUS image score. (a) An EUS image fulfilling the three characteristics, including “repeatability of detection,” “appropriate probe placement,” and “clarity of the five layers of the gastric wall including the lesion”; (b) Inappropriate placement of the probe. The EUS probe is pressed on the lesion; (c) the five layers of the gastric wall including the lesion are not clear.
