I 131 Blood Levels Correlated with Gastric Emptying Determined Radiographically. I. Protein Test Meal

Abstract

Conclusions

1. A characteristic and reproducible curve of radioisotope blood levels was obtained in normal humans and normal dogs following an I¹³¹ labeled protein test meal. 2. Radiographic determination of gastric emptying is necessary for the proper interpretation of data. 3. Delayed gastric emptying significantly altered the radioisotope blood levels. 4. Fainting and change in position may alter radioisotope blood levels.
