Gastric accommodation assessed by ultrasonography

Figure 1 Ultrasonogram showing an oblique frontal section of the proximal stomach in a patient with dyspepsia referred for Ultrasound Meal Accommodation Test (UMAT). The transversal diameter is measured indicating the size of the postprandial proximal stomach and hence indirectly degree of accommodation. Interestingly, one can also observe a gastric contraction (white arrow) in the posterior angular part and progressing towards the antrum.
