Aim. Compare the characterization ability of AFI and NBI for colorectal adenomas. Methods. We prospectively enrolled 58 patients with 89 colorectal adenomas detected by white light colonoscopy. Such lesions were subsequently observed with both AFI and NBI and then treated by endoscopic resection. With respect to the 89 lesions, 3 experienced endoscopists retrospectively evaluated the visualizat...

This paper analyzes the effects of narrowband interferences (NBI) on the performance of a multi-band orthogonal frequency division multiplexing (MB-OFDM) Ultra-wideband (UWB) receiver and proposes efficient schemes for signal reception and extraction of information in the presence of NBI. A study to assess the effects of NBI on the quantization noise in the analog to digital converter (ADC) is ...

UNLABELLED What's known on the subject? and What does the study add? In recent years, more attention has focused on the role of narrow band imaging (NBI) in bladder cancer detection and NBI technology has spread rapidly. It is an important method for diagnosing new or recurrent bladder cancer. But its diagnostic accuracy is still uncertain. This paper summarizes the diagnostic accuracy of NBI i...

Purpose The purpose of this study was to evaluate the efficacy of narrow-band imaging (NBI) as a diagnostic tool for detecting bladder tumors during cystoscopy compared with white light cystoscopy (WLC). Materials and Methods From December 2013 to June 2017, a randomized prospective study was conducted on 198 patients underwent transurethral resection of bladder tumor by a single surgeon. The...

OBJECTIVES Magnifying narrow-band imaging (M-NBI) is more accurate than white-light imaging for diagnosing small gastric cancers. However, it is uncertain whether moving M-NBI images have additional effects in the diagnosis of gastric cancers compared with still images. DESIGN A prospective multicenter cohort study. METHODS To identify the additional benefits of moving M-NBI images by compa...

Previous studies have shown the high diagnostic accuracy of narrow-band imaging magnifying endoscopy (NBI-ME) and Lugol chromoendoscopy with pink-color sign assessment (LCE-PS) for superficial esophageal squamous cell carcinoma (SESCC). However, there has been no controlled trial comparing these two diagnostic techniques. We conducted a randomized noninferiority trial to compare the diagnostic ...

Several single-center studies have investigated whether narrow-band imaging (NBI) cystoscopy is more effective in detecting primary and recurrent non-muscle invasive bladder cancer (NMIBC) compared with white-light imaging (WLI) cystoscopy. In this study, we further evaluated the diagnostic value of NBI cystoscopy compared with WLI cystoscopy for primary NMIBC in a multi-center study. Suspected...

BACKGROUND Magnifying endoscopy (ME) with narrow-band imaging (NBI) has been described as useful in diagnosing colorectal neoplasms. However, there is no standardized simple classification system, and its usefulness in comparison with pit pattern diagnosis by magnifying chromoendoscopy (MC) is unclear. The aim of this study was to investigate the usefulness of evaluations of microvascular archi...

A NBI heated discharge is modeled with TRANSP under the HL-2A condition. LH wave is injected into the target plasma heated by NBI with a nearly symmetric power spectrum to control the current profile. Due to the off-axis driven current and electron heating, an optimized q-profile, of which the magnetic shear is weak in the central region and negative in the mid-plasma region (x~0.5-0.65), is fo...
