Trust your gut? Evaluating non-expert gastric ultrasound performance – A prospective observational cohort study

Examiners with limited experience in ultrasound diagnostics may accurately identify a full stomach in normal-weight volunteers after a standardized training sequence. However, the detected specificity of 0.63 was low, and more focused training on the ultrasound anatomy of an empty stomach may be needed to rule out an empty stomach in a clinical scenario.
