High Definition Endoscopy and Virtual Chromoendoscopy Versus Standard Resolution Endoscopy in Detection of Colon Polyps

High Definition Endoscopy and Virtual Chromoendoscopy Versus Standard Resolution Endoscopy in Detection of Colon Polyps

Over the last years a number of new endoscopic imaging modalities have been introduced (high-definition and virtual chromoendoscopy). Given the theoretical advantage of these new imaging techniques, the investigators aimed to investigate their use for the detection of polyps during colonoscopy.
