magnification endoscopy

The use of digital and optical magnification to enhance the visualization of small lesions within an organ during endoscopy. It is used to identify changes in the esophagus suggestive of Barrett esophagus and may be combined with other imaging techniques (e.g., the spraying of the lining of the examined organ with acetic acid or methylene blue or the illumination of the organ with fluorescent chemicals).
