Abstract

Virtual chromoscopy is a novel technology that enhances endoscopic visualization of superficial mucosal surfaces and microvascular architecture. Currently available virtual chromoscopy techniques include narrow band imaging, Fujinon intelligent color enhancement and I-scan. Refinements are expected to improve detection of the lesions, which will lead to further insight into the pathological processes, in turn, providing guidance in selecting the optimal treatment. Presently, we review the currently available literature regarding virtual chromoscopy and provide technical principles, clinical usefulness, and limitations.
