Laser induced fluorescence in diagnostics of laryngeal cancer.

Differences in autofluorescence between normal and malignant tissues offer new possibilities for detecting and localizing early laryngeal carcinomas. In the present study imaging was performed using a specially designed device that exploits differences in fluorescent properties of normal and cancerous tissues without photodynamic drugs. Fluorescence was induced by helium-cadmium laser, captured by an image-intensified camera and displayed on a video monitor after previous computerization.
