Summary

This study tests whether an artificial intelligence (AI) system can help doctors spot more precancerous polyps and colorectal cancers during colonoscopy compared to standard procedures. Over 3,300 adults scheduled for screening or surveillance will be randomly assigned to AI-assisted or regular colonoscopy. The goal is to see if AI improves detection rates and reduces missed lesions, which could lead to earlier diagnosis and better outcomes.

About 3,300 people

The number the study aims to enrol. It can still change while the study runs.

Expected to start
