Simple clinical method of measuring gastric emptying of solid meals.

The radioisotope techniques used for the measurement of gastric emptying of solid meals in man require complex and expensive scintiscanners of cameras. We have evaluated a simple technique which uses a fixed scintillation detector and compared the results with those obtained from a gamma camera. The rates and patterns of gastric emptying recorded by the two methods correlated well in both healthy volunteers (mean r= 0.95) and patients with duodenal ulcer (mean r =0.89). The scintillation detector provides a reliable and inexpensive method for measurement of gastric emptying of solid meals.
