CONCLUSION
Image1 S endoscopic enhancement system with spectral light modes provides an improved visibility of the vascular patterns defined by the ELS in laryngeal pathologies. A group of otolaryngologists with varying degrees of clinical expertise were able to use Image1 S technology to discriminate between perpendicular and longitudinal vascular patterns with accuracy and consistency. This study demonstrated the usefulness and feasibility of Image1 S endoscopic enhancement system to predict the diagnosis from vascular changes in laryngeal lesions.
