Vital-dye enhanced fluorescence imaging of GI mucosa: metaplasia, neoplasia, inflammation.

Background: Confocal endomicroscopy has revolutionized endoscopy by offering subcellular images of the GI epithelium; however, the field of view is limited. Multiscale endoscopy platforms that use widefield imaging are needed to better direct the placement of high-resolution probes.

Design: Feasibility study.
