A new radioisotopic technic for the measurement of gastric emptying time of solid meal

The suitability of a radiopharmaceutical for measuring gastric emptying time of solid meal is described. The gastric emptying T/sup 1///sub 2/ value of solid meal in normal individuals has been established. Both animal and human experiments indicate /sup 99m/Tc-DTPA to be an ideal nonabsorbable marker for determining gastric emptying rate and for other gastrointestinal studies as well. Studies are now underway to determine gastric emptying time in patients with gastrectomy and gastrojejunostomy, vagotomy, pyloroplasty, etc.
