Ulcer shadow

Ulcers are due to direct signs of gastric and duodenal ulcers. Stomach and duodenal ulcer (gastric ulcer, duodenal ulcer) is a common disease, which occurs in 20-50 years old. The incidence of duodenal ulcer is about five times that of gastric ulcer. It is more common in small bends. Its tangent position is papillary, tapered or other shapes. The edges are smooth and neat, and the density is uniform. The bottom is flat or slightly uneven.
