¹The second layer is the deep layer of the mucosa, the third layer is the submucosa and the interface between the submucosa and the muscularis propria.

²Level 0 corresponds to the anechoic pattern, level 1 corresponds to the fourth layer of the gastric wall, presenting as hypoechoic, level 2 corresponds to the echo of the splenic parenchyma, showing medium-low echo, the echo of level 3 is between level 2 and level 4, presenting as medium-high echo, level 4 corresponds to the third layer of the gastric wall, showing high echo.

³The combined echo pattern of level 2 and 4.

EUS: Endoscopic ultrasonography.
