Well established scientific literature demonstrates the application of spectroscopy for interrogation of tissue in vivo to objectively categorize the tissue as either normal or diseased.
Abnormal tissue absorbs and emits light very differently than normal tissue.
Subtle biochemical and structural changes occur in tissue at various disease stages, such as differences in hemoglobin concentration, mucosal thickening, capillary perfusion, cell definition, and nuclear size. This combination enables the detection of abnormalities sooner, in the deeper epithelial layers where they typically originate. The result is more effective disease detection and management, fewer false positives, fewer false negatives, and better overall patient care. Dr. Louis Burke, Chief of Colposcopy at Boston's Beth Israel Deaconess Medical Center, recently conducted a study using a prototype MediSpectra system on women referred for colposcopy after an abnormal Pap smear.
