Double-contrast upper GI series is the most diagnostic procedure to demonstrate a gastric ulcer as it combines the use of both barium sulfate and air, which allows for better visualization and delineation of the ulcer margins. The single-contrast barium sulfate upper GI series may not provide enough contrast to visualize the ulcer. The oral water-soluble upper GI series and carbon dioxide upper GI series are not commonly used for evaluating gastric ulcers.
