An assessment of dynamic gastric scanning with 99Tcm-pertechnetate

Abstract

Following intravenous injection, technetium‐99m (⁹⁹Tc^m) is selectively taken up by the stomach, and this uptake, which is stimulated by pentagastrin, may be quantified using a gamma camera. Using this property of ⁹⁹Tc^m as a means of assessing gastric function, we found that the mean rate of ⁹⁹Tc^m uptake was significantly greater in 24 duodenal ulcer patients than in 10 healthy controls (P99Tc^m (P99Tc^m reflects a function of the stomach which is similar to acid secretion, scanning did not give a good estimate of acid secretion in this group of subjects.
