Vascularization from Flexible Imaging Color Enhancement (FICE) for polyp localization

Background. Virtual chromoendoscopy is an imaging technology that helps in better visualizing the gastrointestinal tract effectively. Recently, the flexible imaging color enhancement (FICE) technique developed by Fijifilm has been considered an alternative to traditional dye spraying. This results in a clearer visualization of the vascular patterns than through the traditional white light endoscopy imaging methods. The performance of vasculature based polyp localization in both traditional and corresponding virtual coloration by FICE was analyzed. Conclusion. Our analysis showed that FICE based images vascularization features provides a better discrimination of polyps than the traditional white light endoscopy images.
