Published: March 2023

Introduction: Narrow-band imaging (NBI) is an advanced endoscopic technique that enhances the mucosal neovascularization. The utilization of narrow-band imaging on the detection of nasal lymphomas is not well-established.

Aim: To present a clinical case whose nasal lymphoma was detected with the aid of NBI.

Case Report: A 91-year-old male presented to the ear, nose, and throat clinic with right persisting nasal obstruction for 4 months. NBI revealed a well demarcated lesion with an elongated vessel on the surface of the right inferior nasal turbinate. Histopathologic analysis of tissue specimen proved to be extranodal NK/T-cell lymphoma, nasal type.

Conclusions: NBI is useful for the detection of nasal lymphomas. NBI may be a valuable screening tool for nasal lymphomas as it is non-invasive and affordable.

Use of Narrow Band Imaging to Guide Endobronchial Biopsy for Suspected Sarcoidosis.

J Bronchology Interv Pulmonol

April 2025

Department of Medicine, Division of Respirology, University of Calgary, Calgary, AB.

Background: Diagnosis of sarcoidosis often involves endobronchial biopsy (EBB), but studies have shown varying yields for EBB in suspected sarcoidosis, partly due to differences in identifying abnormal mucosa under white light (WL). Narrow band imaging (NBI) may assist in the visualization of abnormal mucosa, but its role in sarcoidosis remains to be characterized.

Methods: Individuals referred for suspected sarcoidosis were considered for enrollment.

Band Tailoring Enabled Perovskite Devices for X-Ray to Near-Infrared Photodetection.

Adv Sci (Weinh)

Perovskite semiconductors have shown significant promise for photodetection due to their low effective carrier masses and long carrier lifetimes. However, achieving balanced detection across a broad spectrum-from X-rays to infrared-within a single perovskite photodetector presents challenges. These challenges stem from conflicting requirements for different wavelength ranges, such as the narrow bandgap needed for infrared detection and the low dark current necessary for X-ray sensitivity.

Prospects for Narrow Band Imaging Magnification Endoscopy in Oral Lesions: Recommendations from Oral and Maxillofacial Surgeons and a Gastroenterologist.

Cancers (Basel)

Division of Oral and Maxillofacial Surgery, Department of Oral and Maxillofacial Reconstructive Surgery School of Dentistry, Iwate Medical University, Morioka 020-8505, Iwate, Japan.

Narrow band imaging (NBI) magnification endoscopy for the diagnosis of early-stage oral cavity-related cancer and precancerous lesions can recognize oral lesions as brownish areas, and can observe intraepithelial papillary capillary loops (IPCLs) in the mucosa and submucosa to make a qualitative diagnosis of the lesion and highlight the mucosal surface microstructure to facilitate appropriate diagnosis and early treatment. IPCLs are classified from Type 0 to IV: Type 0 is normal mucosa or no blood vessels observed, e.g.
