BACKGROUND AND STUDY AIMS  Magnifying narrow-band imaging (M-NBI) enables detailed observation of microvascular architecture and can be used in endoscopic diagnosis of colorectal lesion. However, in clinical practice, differential diagnosis and estimation of invasion depth of colorectal lesions based on M-NBI findings require experience. Therefore, developing computer-aided diagnosis (CAD) for ...

Using narrow-band imaging (NBI), the micro morphology of polyp surfaces was visualized at high resolution when the contrast between the lesions and the surrounding tissue areas was intensified. The objective of the study was to compare NBI and conventional white light endoscopy (C-WLI) for diagnostic efficacy and treatment of children with Peutz-Jeghers syndrome (PJS), a rare autosomal dominant...

Abstract This paper describes scalings of the H-mode confinement database neutral beam injection (NBI)-lower hybrid wave (LHW) and electron cyclotron resonant heating-LHW plasmas in EAST tokamak. Fundamental information details calculation thermal energy time are presented. The result scaling model <mml:math xmlns:mml="http://www.w3.org/1998/Ma...

Objective: Superficial Barrett’s esophageal adenocarcinoma (S-BEA) has been treated by endoscopic procedures. Especially, intramucosal carcinomas have been treated by endoscopic mucosal resection (EMR) or endoscopic sub mucosal dissection (ESD). It is important to diagnose sub mucosal invasive lesions by endoscopy. However, it is difficult to diagnose with sub mucosal or mucosal BEA. Aim of thi...

Narrow band imaging (NBI) is reported to improve the diagnostic accuracy of head and neck cancers. The purpose of this review was to evaluate the diagnostic accuracy of NBI in the literature. A systematic review was performed in PubMed, Web of Knowledge, and the Cochrane Library until March 2015. Two reviewers independently assessed articles and extracted data. Meta-analyses were performed in M...

Introduction. This study examined whether magnifying endoscopy with NBI observation (ME-NBI) could be useful selecting the appropriate treatment for submucosal invasive cancer (SM cancer). Patients and Methods. We analyzed 515 cases of colon tumors excised endoscopically or surgically. We classified capillary network pattern into four types according to the degree of dilatation, irregularity, a...

Accurate simulations of Neutral Beam Injection (NBI) in tokamak plasmas are vitally important for the analysis of present experiments since NBI is a main heating and current drive tool used in many tokamaks. Different numerical techniques including Monte-Carlo (MC) simulations of beam particles and the solution of the Fokker-Planck (FP) equation for the beam particle distribution function are u...

Neutral beam injection (NBI) is known to significantly affect radial transport in a toka-mak plasma. However, the effect on collisional transport, accounting for strong toroidal plasma rotation, which is typical in the presence of NBI, had not been addressed. Furthermore , recent observations have shown poloidal velocities, in the presence of NBI, significantly in excess of the standard neoclas...

Urothelial carcinoma of the bladder and upper tract is primarily diagnosed by white light endoscopy, which has well-known limitations that contribute to the increased risk of tumor recurrence and progression. Narrow band imaging (NBI) is an optical imaging technology that facilitates detection of tumor vasculature and differentiation of benign urothelium from neoplastic tissue. For urothelial c...

Transoral robotic surgery (TORS) is a less invasive treatment that is becoming popular all over the world. One of the most important factors for achieving success in TORS is the ability to determine the extent of resection during the procedure as the extent of resection in the laryngopharynx not only affects oncological outcomes but also directly affects swallowing and voice functions. Magnifyi...
