title: [Gastric emptying of an ordinary meal in man. Study by a radio-isotopic method (author's transl)].
abstract: A radio-isotopic method was used to study the gastric emptying of an ordinary meal in 15 control subjects. The technique developed may be used for direct measurement of the early phase of gastric emptying and a simultaneous study of emptying of liquid and solid phases, respectively labelled with Tc99m and Cr51. Emptying of the liquid phase of the meal takes place in accordance with a mono-exponential curve in relation to time, the T 1/2 of which is 54 min +/- 6 (MSD). Emptying of the solid phase is significantly slower than that of the liquid phase. The reproductibility of the method was confirmed and the imprecision of each measurement does not exceed 5%.
