NBI and NBI Combined with Magnifying Colonoscopy
Although magnifying chromoendoscopy had been a reliable diagnostic tool, narrow-band imaging (NBI) has been developed in Japan since 1999 and has now replaced the major role of chromoendoscopy because of its convenience and simplicity. In this paper, we principally describe the efficacy of magnifying chromoendoscopy and magnifying colonoscopy with NBI for detection, histological prediction, est...
متن کاملPolyp Segmentation in NBI Colonoscopy
Endoscopic screening of the colon (colonoscopy) is performed to prevent cancer and to support therapy. During intervention colon polyps are located, inspected and, if need be, removed by the investigator. We propose a segmentation algorithm as a part of an automatic polyp classification system for colonoscopic Narrow-Band images. Our approach includes multi-scale filtering for noise reduction, ...
متن کاملComparison of Diagnostic Efficacy Between AFI, NBI, and AFI Combined with NBI for Colonic Cancers: A Meta-Analysis
BACKGROUND/AIMS Advanced endoscopic imaging technologies have been used for the early detection and differentiation of colonic cancers recently. We aim to evaluate the diagnostic efficacy of autofluorescence imaging (AFI), narrow-band imaging (NBI), and AFI combined with NBI for colonic cancers. MATERIALS AND METHODS We searched Medline/PubMed, Embase, Web of Science, and Cochrane Library dat...
متن کاملMagnifying endoscope with NBI to predict the depth of invasion in laryngo-pharyngeal cancer.
OBJECTIVES/HYPOTHESIS To examine if macroscopic classification with a magnifying gastrointestinal endoscope with narrow band imaging (ME-NBI) is useful in predicting pathological depth of tumor invasion in laryngo-pharyngeal cancer. STUDY DESIGN Retrospective study. METHODS Preoperative endoscopy reports and postoperative pathological reports on 139 laryngo-pharyngeal cancer lesions were re...
متن کاملA System for Colorectal Tumor Classification in Magnifying Endoscopic NBI Images
In this paper we propose a recognition system for classifying NBI images of colorectal tumors into three types (A, B, and C3) of structures of microvessels on the colorectal surface. These types have a strong correlation with histologic diagnosis: hyperplasias (HP), tubular adenomas (TA), and carcinomas with massive submucosal invasion (SM-m). Images are represented by Bag-of-features of the SI...
