Figure 1: (a) Sonographic image of the gastric antrum in the epigastric area with empty stomach. The muscularis propriae is seen as a hypoechoic layer within the gastric wall. SMA = superior mesenteric artery. (b) Gastric ultrasound images of the antrum of solid content. The mixture of echogenicity called “frosted-glass” appearance. The antral cross-sectional area is calculated using the Free tracing method
