Ramanspectroscopy in Barrett's Esophagus

In the search for means to enhance the surveillance of BE, optical spectroscopy is emerging
as a candidate with high potential. Optical spectroscopic techniques measure specific
light-tissue interactions, such as fluorescence, elastic scattering, and Raman (inelastic)
scattering, which provide objective and quantitative diagnostic information about the
molecular and/or structural status of tissue. Moreover, optical spectroscopy has the
capacity to identify tissue pathology in situ in a rapid and non-destructive fashion. Among
the optical spectroscopic techniques, near-infrared Raman spectroscopy (NIRS) is
particularly promising because of the wealth of molecular-specific information contained in
its spectra
