Autofluorescence imaging of early colorectal cancer

J Biophotonics. 2011 Aug;4(7-8):490-7. doi: 10.1002/jbio.201100013. Epub 2011 May 9.


Autofluorescence imaging (AFI) is expected to better detect colorectal neoplasms than the conventional white light imaging (WLI). The AFI image of colorectal cancer is different according to its macroscopic type. Protruded lesion, which is the most common macroscopic type of colorectal neoplasms, is revealed as magenta protruded lesion. Flat lesion, which is uncommon macroscopic type, is presented as distinct magenta area surrounding green mucosa using AFI. And depressed lesion, which is rare macroscopic type, is revealed as green area surrounded by magenta mucosa.
