High-definition imaging and NBI—improving colonic imaging?

Abstract

Detecting and characterizing colonic polyps using high-definition imaging and narrow-band imaging (NBI) has yielded modest results. Now, two randomized studies have substantiated the role of NBI in reducing polyp miss rates in patients with hyperplastic polyposis syndrome, and in differentiating adenomas from hyperplastic polyps, although with no improvement in adenoma detection rates.
