Abstract
|
|
|
The desire to better recognized such malignancies, which may be difficult to distinguish from inflammation
or trauma, has accelerated the development of endoscopy with new optical technologies. Narrow-band imaging (NBI) is a novel endoscopic technique that may enhance the accuracy of diagnosis using narrow-bandwidth filters in a red-green-blue (RGB) sequential illumination system. The sensitivity of this technique is too low to diagnose esophageal cancer based only on the resulting dark brown color change. Furthermore, observing lesions in the stomach, which has a wide lumen, is not useful because the result is dark, rough images. Microstructures and the microvasculature in the mucosa could be clearly observed using narrow band imaging during magnification endoscopy, and detailed evaluation of the lesions was possible. Thus, narrow band imaging can be expected to not only assume the role of electronic chromoendoscopy but also to act as an ‘optical biopsy,’ making the diagnosis of lesions possible without performing
biopsies through its association with magnification endoscopy.
