Full-Field Optical Coherence Tomography (FFOCT) for Evaluation of Bronchoscopic Small Biopsy Specimens

This study is testing a new imaging technology called full-field optical coherence tomography (FFOCT) — which creates very detailed, microscopic images of tissue without processing it — to evaluate small tissue samples taken during bronchoscopy (a procedure to view the airways) for lung diagnosis or staging. **You may be eligible if...** - You are 18 years of age or older - You are undergoing a bronchoscopy procedure as part of your standard medical care for lung diagnosis or staging - Small biopsy samples are being collected during your bronchoscopy (by standard needle or biopsy techniques) **You may NOT be eligible if...** - You have a standard contraindication to bronchoscopy (e.g., bleeding disorders, blood thinners, severe respiratory failure, medical instability) - You are pregnant Talk to your doctor to see if this trial is right for you.
