The relationship of body size to rates of gastric emptying of solid food was investigated in order to obtain data that may allow this variable to be considered when populations of varying size are studied. Rates of gastric emptying were measured using a beef stew meal to which were added pieces of chicken liver tagged with [99mTc]sulfur colloid, and following the passage of the isotope through the gastrointestinal tract with intermittent gamma-imaging. Results showed an inverse linear relationship between gastric emptying rates and body surface area, and between gastric emptying rates and body weight. The variable of body size must be taken into account when measurements of gastric emptying of solid food are measured.
研究了体型与固体食物胃排空速率之间的关系，以便获得在研究不同体型人群时能够考虑这一变量的数据。使用添加了用[99mTc]硫胶体标记的鸡肝片的炖牛肉餐来测量胃排空速率，并通过间歇性γ成像跟踪同位素在胃肠道中的通过情况。结果显示胃排空速率与体表面积之间以及胃排空速率与体重之间呈负线性关系。在测量固体食物的胃排空时，必须考虑体型这一变量。
