Overview

Optical endoscopy with white light and fluorescence enhances mucosal visualization. Targeted fluorescent agents enable molecular imaging during procedures.

Technique

Narrow band imaging autofluorescence and targeted probes increase lesion contrast. Real time visualization guides biopsy and resection.

Clinical Uses

Gastrointestinal and pulmonary endoscopy intraoperative tumor margin assessment and sentinel node mapping.

Limitations and Safety

Agent safety and specificity vary. Interpretation requires training and adjunctive pathology.
