- Original description
This clinical trial compares the addition of needle-based confocal laser endomicroscopy (nCLE) and fluorescein to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS TBNA) with EBUS TBNA alone for the diagnosis of lung cancer in patients with peripheral pulmonary nodules. EBUS TBNA is a diagnostic procedure that can be used to sample lung tissue. nCLE is a novel high-resolution imaging technique that uses a laser light to create real-time microscopic images of tissues. It can be integrated into needles allowing real-time cancer detection during endoscopy. Fluorescein is an imaging agent that can be used to visualize tissue. Using nCLE and fluorescein in combination with EBUS TBNA may be more effective in diagnosing lung cancer than using EBUS TBNA alone.Read full original descriptionShow less
