Novel Computer-enhanced Visualization of Volumetric Laser Endomicroscopy Correlates Endoscopic and Pathological Images

Targeting neoplasia using volumetric laser endomicroscopy with laser marking.

Volumetric laser endomicroscopy (VLE) is a recent advanced imaging technology that allows high resolution microstructure imaging of the esophagus and gastric cardia; it has been increasingly used in Europe and the USA [1–3]. The system has been recently upgraded to include a laser marking device that places cautery marks on the mucosa to provide targets for histology. We report a case of an inc...

Advances in Endoscopic Visualization of Barrett's Esophagus: The Role of Confocal Laser Endomicroscopy

Many endoscopic imaging modalities have been developed and introduced into clinical practice to enhance the diagnostic capabilities of upper endoscopy. In the past, detection of dysplasia and carcinoma of esophagus had been dependent on biopsies taken during standard white-light endoscopy (WLE). Recently high-resolution (HR) endoscopy enables us to visualize esophageal mucosa but resolution for...

Volumetric Laser Endomicroscopy in Patients With Barrett Esophagus.

Volumetric laser endomicroscopy can target neoplasia not detected by conventional endoscopic measures in long segment Barrett's esophagus.

Methods and study aims: The incidence of esophageal cancer is rising despite increased surveillance efforts. Volumetric laser endomicroscopy (VLE) is a new endoscopic imaging tool that can allow for targeted biopsy of neoplasia in Barrett's esophagus. We report a series of 6 patients with long-segment Barrett's esophagus ( > 3 cm), who underwent a session of endoscopy with volumetric laser endo...

Motion Artifact Detection in Confocal Laser Endomicroscopy Images

Confocal Laser Endomicroscopy (CLE), an optical imaging technique allowing non-invasive examination of the mucosa on a (sub)cellular level, has proven to be a valuable diagnostic tool in gastroenterology and shows promising results in various anatomical regions including the oral cavity. Recently, the feasibility of automatic carcinoma detection for CLE images of sufficient quality was shown. H...
