Which of the following agent does not increase the sensitivity of Tc- peechnate scan?
Pentagastrin, H2 blockers and glucagon- enhance detection of ectopic gastric mucosa in Meckel's diveiculum by Tc-peechnate scan. Glucagon- relaxes the smooth muscles of GIT and decreases peristalsis. Pentagastrin- potent stimulator of gastric secretions, increases uptake and secretion of peechnetate by the gastric mucosa and stimulates gastrointestinal motility. Histamine H2 blockers (Cimetidine) block secretion from the cells and increase gastric mucosa uptake
Glucagon
Metoclopramide
Cimetidine
Pentagastrin
Small intestine
