Novel methods of enhanced endoscopic imaging.
Endoscopy has become an essential part of the practice of gastroenterology. Techniques exploiting previously unused properties of light have demonstrated the potential to enhance the ability to make clinical diagnoses without removing tissue as has been standard practice for decades. The term used for many of these techniques is "optical biopsy" and, although not yet widely available, enthusiasm for such techniques has grown as has research in their potential clinical utility.
