In recent years, image-enhanced endoscopy has been reported the usefulness to evaluate disease activity of UC. Dual red imaging (DRI) is a new imaging technology has been introduced that uses 3 wavelengths for illumination: 540nm, 600nm and 630nm. DRI was closely correlated with both the endoscopic and the histological grades, and developed the DRI score. However, no study has validated DRI score and not actually used in real world. Therefore, the aim of this study is to validate DRI score prospectively.
Efficacy
The Mayo endoscopic scores, UCEIS, DRI scores, and histologic scores were evaluated.

Male and Female
UC patients whom colonoscopy was scheduled between May and October 2019 at Gunma University Hospital
Patients with severe or fulminant disease were excluded. We also excluded patients who cannot deny of mucosal cytomegalovirus infection and coexistence of infectious colitis.

The colorectum was divided into six segments (cecum, ascending colon, transverse colon, descending colon, sigmoid colon, and rectum). For each segment we use the White light imaging (WLI) mode to evaluate UC activity, and the imaging mode was switched to DRI to evaluate it
