Decade of patient stomach imaging culminates in NTU’s AI Gastroscopy for precision detection of precancerous lesions

Traditional gastroscopy, while effective in observing the stomach's condition, struggles to accurately assess the risk of gastric cancer. The development of gastric cancer typically progresses through a series of precancerous stages, including Helicobacter pylori infection, chronic gastritis, atrophic gastritis, and ultimately intestinal metaplasia. Currently, doctors must rely on endoscopic images and pathology reports to determine if a patient has precancerous lesions, a process that is time-consuming, labor-intensive, and costly, with a particular scarcity of resources in remote areas.
