Scintigraphic measurement of gastric emptying and ultrasonographic assessment of antral area: relation to appetite.
Ultrasound measurement of gastric emptying has potential advantages over scintigraphy, but there is little information about its accuracy. ⋯ Ultrasound measurements of gastric emptying are: (a) of comparable sensitivity to scintigraphy in quantifying emptying of both low and high nutrient liquids (b) correlate with postprandial satiation, suggesting that the latter may be mediated by antral distension.
