Advances in endoscopic imaging: Advantages and limitations

open access: yesJournal of Digestive Endoscopy, 2012
Endoscopic imaging is emerging beyond the confines of traditional white light endoscopy. There is a plethora of advanced imaging technologies which aim to improve visualization of the vascular network and surface texture of the mucosa and thereby improve

First principles of modelling the stabilization of microturbulence by fast ions [PDF]

open access: yes, 2018
The observation that fast ions stabilize ion-temperature-gradient-driven microturbulence has profound implications for future fusion reactors. It is also important in optimizing the performance of present-day devices.

Impact of Narrow Band Imaging in Pre-Operative Assessment of Suspicious Oral Cavity Lesions: A Systematic Review [PDF]

open access: yesIranian Journal of Otorhinolaryngology, 2021
Introduction: Narrow band imaging (NBI) is a powerful tool that allows visualizing the mucosal and submucosal vasculature. Among the available diagnostic techniques, NBI is one of the most valid for early detection of oral squamous cell carcinoma (OSCC).

The role of narrow band imaging in colorectal polyp detection

open access: yesBiomolecules & Biomedicine, 2017
Colonoscopic detection and removal of polyps represent the most important prevention method for colorectal cancer. We aimed to investigate the diagnostic yield of narrow band imaging (NBI) colonoscopy for polyp detection compared with standard ...

Narrow Band Imaging: Technology Basis and Research and Development History [PDF]

open access: yesClinical Endoscopy, 2015
The first launch of narrow band imaging (NBI) was in 2005. Since then, in most countries where gastrointestinal endoscopies are performed, NBI is the most commonly used optical digital method of performing image-enhanced endoscopy.

Comparison of diagnostic efficacy between AFI, NBI, and AFI combined with NBI for colonic cancers: A meta-analysis

open access: yesThe Saudi Journal of Gastroenterology, 2017
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
