Fluorescence and Raman spectroscopy.
Reflectance spectroscopy is an emerging technology which provides rapid and safe evaluation of tissue for dysplasia and ischemia. The probe-based devices can be passed through most endoscopes. Current applications include detection of dysplasia in Barrett's esophagus, colitis, and colon polyps.
