Feasibility study of autofluorescence mammary ductoscopy.

We report the technical feasibility of autofluorescence ductoscopy in the ex-vivo setting. The current imaging algorithm for visualizing tumor tissue against the normal tissue background, although developed and optimized for other organs, appears to provide discrimination between intraductal tumor and normal ductal tissue. Point fluoroscopy is also performed. Although the optical "geometry" for this is different, the findings are consistent with the imaging observations.
