Graphical representation of the different gastric sections. A representative cross-section of the five layers of the gastric antrum that can be seen sonographically is demonstrated on the right.

Fig 2
Patient positioning for performing gastric ultrasound in the RLD position, with the ultrasound transducer placed in the epigastrium beneath the xiphoid process.
Fig. 3
Fig 3
Ultrasound images of an empty gastric antrum, with the key sonographic landmarks identified on the right. SMA, superior mesenteric artery.
Fig. 4
Fig 4
Ultrasound images of different antral qualitative appearances. (A) Gastric antrum (A) containing fluid with some air bubbles. (B) Gastric antrum containing fluid with a ‘starry night’ appearance. Antral CSA was calculated with a calliper trace tool (yellow dotted line), and a CSA of 27.34 cm2 was quantified. (C) Gastric antrum after recent ingestion of solids, with a ‘frosted glass’ appearance. The anterior antral wall is visible, but there are no clear structures seen deep to the anterior antral wall. (D) Gastric antrum containing solids, with heterogeneous echogenicity representing different consistency of solids consumed. Note the thin, hypoechoic muscularis propriae compared to Fig 3. SMA, superior mesenteric artery.
