Colorectal Neoplasm, Colonic Polyps
Clinical Study of Real Time Colorectal Polyp Diagnosis During Colonoscopy - the VALID Colonoscopy Study
The investigators hypothesize that high definition colonoscopy with close focus narrow band imaging features has a high diagnostic accuracy for colorectal polyp histology, and can replace formal pathologic assessment in cases of…

Gastroesophageal Reflux Disease
Narrow-band Imaging, Autofluorescence Imaging and Gastroesophageal Reflux Disease
Aim of this study is to compare the efficacy of narrow band imaging (NBI) and autofluorescence imaging (AFI) to distinguish subtle mucosal change related to acid reflux that is not visible in standard white light imaging (WLI)…

Routine Endoscopy
Study Comparing Flexible Spectral-Imaging Color Enhancement (FICE) With Olympus Narrow Band Imaging (NBI)
The study is intended to test the image quality of the FICE system to the predicate device, Narrow Band Imaging (NBI). The hypothesis is the images are of equal quality.
- Trial name
- FICE (NCT02005393)
- Testing
- FICE Image Acquisition followed by NBI Image Acquisition
- Where
- United States
- Volunteers
- 20 people, healthy volunteers welcome

Colon Cancer
Narrow-Band Imaging Versus Standard White Light for the Detection of Serrated Lesions in the Proximal Colon
This is a study to determine if using Narrow-Band Imaging of the colon, rather than the usual white light on the colon, will improve the detection of a type of polyp called serrated.
- Trial name
- NCT01572428
- Testing
- Inspection with Narrow-Band Imaging(NBI), Standard White Light
- Where
- United States
- Volunteers
- 898 people, healthy volunteers welcome

Colorectal Neoplasms, Colonic Polyps
Study of Flat Polyp Detection Using New Narrow Band Imaging (NBI) Compared to White Light Colonoscopy - The FIND FLAT Colonoscopy Study
We hypothesize that high definition narrow band imaging (NBI) colonoscopy compared to high definition white light colonoscopy will detect an increased number of nonpolypoid (flat and depressed) colorectal neoplasm.
- Conditions
- Colorectal Neoplasms, Colonic Polyps, Colorectal Cancer
- Trial name
- NBI (NCT01310699)
- Testing

Colonic Neoplasms
Clinical Evaluation of Narrow Band Imaging Colonoscope
The purpose of the study is to determine if colonoscopic examination using a colonoscope with a narrow band imaging light is more effective at detecting polyps compared to a colonoscope with standard full spectrum white light.

- NCT00628147
- Testing
- Narrow band imaging colonoscope
- Where
- United States
- Volunteers
- 284 people, healthy volunteers welcome
