The sequential scintiscanning technique was used to determine gastric emptying rates in adult human subjects after ingestion of a meal of cornflakes and milk to which a gamma-emitting radioactive isotope had been added.Comparison of emptying rates using (113m)In DTPA chelate and (51)Cr sodium chromate showed that significantly slower rates were recorded with chromate, and studies in vitro demonstrated adsorption of chromate to the solid component of the meal. The results imply that the liquid phase of the gastric contents after a meal is discharged through the pylorus more rapidly than the solid phase. Scintiscanning with indium chelate provides a measurement of the emptying of the liquid phase of the gastric contents.
采用序列闪烁扫描技术,在摄入添加了放射性同位素的玉米片和牛奶餐后,对成年人体的胃排空率进行了测定。使用(113m)In DTPA 螯合物和(51)Cr 铬酸钠比较排空率的结果表明,铬酸盐的排空率显著较慢,并且体外研究表明铬酸盐被吸附到膳食的固体成分上。这些结果表明,餐后胃内容物的液相比固相更快地通过幽门排出。铟螯合物闪烁扫描提供了胃内容物液相排空的测量。
