AI-driven Narrow-band Imaging Score for Disease Assessment and Outcome Prediction in Ulcerative Colitis

This study is testing whether an AI-powered scoring system applied to narrow-band imaging (a special colonoscopy technique that highlights blood vessels in the bowel lining) can accurately assess disease severity and predict outcomes in people with ulcerative colitis. **You may be eligible if...** - You are between 18 and 75 years old - You have had a confirmed diagnosis of ulcerative colitis for at least 6 months - You are undergoing a colonoscopy to assess disease activity or for cancer surveillance **You may NOT be eligible if...** - You have conditions that make colonoscopy or biopsies unsafe (e.g., toxic megacolon, severe blood clotting problems) - Your bowel preparation before the procedure was inadequate - You are pregnant or breastfeeding - You have been in another experimental study within the past 30 days Talk to your doctor to see if this trial is right for you.
