Autofluorescence and Narrow Band Imaging in Barrett's Esophagus

Gastroenterology Clinics of North America, 2010
This review discusses the application of 2 novel imaging techniques in Barrett's esophagus: autofluorescence imaging and narrow band imaging (NBI). Autofluorescence as well as NBI may help to direct endoscopic therapy for early neoplasia in Barrett's esophagus; their value in daily practice, however, seems to be limited and needs further evaluation.

Subglottic cyst: The role of narrow-band imaging

International Journal of Pediatric Otorhinolaryngology, 2012
A subglottic cyst is a rare cause of neonatal upper airway obstruction, which may be misinterpreted as a subglottic hemangioma. With the advent of narrow-band imaging, the application of its unique features in analyzing the mucosa surface's vascular structures in pediatric subglottic lesions remains to be investigated.

Narrow Band Imaging in Borderline Ovarian Tumor

Journal of Minimally Invasive Gynecology, 2010
Fig. 1. Conventional laparoscopy using white light. Borderline ovarian tumors (BOT) comprise 15% of all epithelial ovarian neoplasms, and the outcome is much better than for women with invasive ovarian cancer [1]. The histologic study of peritoneal implants represents a crucial factor in the clinical management of patients with BOT because it ...

Narrow-Band Imaging Bronchoscopy in Tracheobronchial Amyloidosis

Journal of Bronchology & Interventional Pulmonology, 2014
Primary tracheobronchial amyloidosis (TBA) is a rare disease characterized by extracellular focal or diffuse submucosal deposits of amyloid proteins. Various types of endobronchial lesions have been described in TBA when bronchoscopy is performed using white light.

Narrow band imaging cholangioscopy in hilar cholangiocarcinoma

Indian Journal of Gastroenterology, 2010
Per oral cholangioscopy has been developed as a diagnostic modality for evaluation of bile duct lesions. Per oral cholangioscope with narrow band imaging (NBI) system can provide good quality images of bile duct lesions. There is limited data on per oral cholangioscopy using NBI in biliary tract diseases.

Narrow band imaging in the diagnosis of bladder schistosomiasis

BMJ Case Reports, 2020
A 23-year-old man presented to us with multiple episodes of visible haematuria associated with dysuria, but no other symptoms suggestive of infection. His physical examination was completely unremarkable. On detailed evaluation of history, it was noted that he was treated for urinary schistosomiasis as a child in Sudan. A diagnostic flexible cystoscopy,

High-resolution narrow band imaging endoscopy

Gut, 2008
Oesophageal, gastric and colorectal neoplasms made up 24% of worldwide cancer mortality in 2002.1 Early detection of these neoplasms or their precursors may be the only chance to reduce this high mortality. Endoscopy is currently the initial procedure used for early detection of gastrointestinal (GI) cancers worldwide.

Narrow Band to Image Registration in the Insight Toolkit

2003
This paper introduces the new concept of narrow-band to image registration. Narrow-banding is a common technique used in the solution of level set approaches to image processing. For our application, the narrow-band describes the shape of an object by using a data structure containing the signed distance values at a small band of neighboring pixels ...
