Third-Generation Narrow-Band Imaging Versus White-Light Imaging for the Detection of Early Gastric Cancer: A Randomized Controlled Study. [PDF]

DEN Open
ABSTRACT Objectives The endoscopic system EVIS X1 with improved image quality has been introduced into clinical practice. We examined whether third‐generation narrow‐band imaging (3G‐NBI) is more effective than white‐light imaging (WLI) for detecting early gastric cancer (EGC). Methods Our study, performed at a single center, had a parallel‐group, open‐

Colonic Malakoplakia With an Adenomatous Appearance on Magnification Endoscopy: A Case Report. [PDF]

DEN Open
ABSTRACT Malakoplakia is a rare chronic granulomatous disease associated with impaired macrophage phagocytosis of bacteria. Because colonic malakoplakia presents with varied endoscopic appearances, its characteristic features have not been clearly defined, and differentiation from colorectal neoplasms during endoscopy may be difficult. We report a case

European guidelines from the EHTG and ESCP for Lynch syndrome: an updated third edition of the Mallorca guidelines based on gene and gender

BJS (British Journal of Surgery), EarlyView., 2020
Recommendations for clinical and molecular identification of LS, surgical and endoscopic management of LS‐associated colorectal cancer and preventive measures for cancer were produced. The emphasis was on surgical and gastroenterological aspects of the cancer spectrum.

Narrow Band Imaging for the Detection of Gastric Intestinal Metaplasia and Dysplasia During Surveillance Endoscopy [PDF]

, 2010
Surveillance of premalignant gastric lesions relies mainly on random biopsy sampling. Narrow band imaging (NBI) may enhance the accuracy of endoscopic surveillance of intestinal metaplasia (IM) and dysplasia. We aimed to compare the yield of NBI to white

Compressive narrowband interference detection and parameter estimation in direct sequence spread spectrum communication

IET Signal Processing, 2022
The Shannon‐Nyquist sampling theorem that is based on narrowband interference (NBI) detection and parameter estimation methods in direct sequence spread spectrum (DSSS) communication is limited by the high sampling rate.

Diagnostic limitations of magnifying endoscopy with narrow-band imaging in early gastric cancer

Endoscopy International Open, 2020
Background and study aims Magnifying endoscopy with narrow band imaging (M-NBI) has made a huge contribution to endoscopic diagnosis of early gastric cancer (EGC). However, we sometimes encountered false-negative cases with M-NBI diagnosis (i.

Low-magnification narrow-band imaging for small gastric neoplasm detection on screening endoscopy

VideoGIE, 2022
Background and Aims: Microsurface patterns of the gastric mucosa can be observed using magnifying narrow-band imaging (M-NBI). However, the efficacy of M-NBI at low-magnification (LM-NBI) screening for detecting small gastric neoplasms is unclear ...

Comparison Study of Time Synchronization in NC-OFDM Systems Based on Symmetric Correlator

Jurnal Elektronika dan Telekomunikasi, 2019
NC-OFDM as one of the candidates for the Cognitive Radio (CR) system has many challenges in the synchronizing time. This is due to the frequency sharing which can cause Narrowband Interference (NBI), which causes a very significant time synchronization ...
