Red Dichromatic Imaging for Improving Post-Biopsy Bronchoscopic Field Visibility

Brief Summary

The goal of this observational study is to learn whether red dichromatic imaging (RDI) can help doctors see the bronchoscopic field more clearly after a biopsy. The study will include adults who need a bronchoscopic biopsy because doctors can see an abnormal area inside the airway.During a bronchoscopic biopsy, bleeding can happen after tissue is taken. Blood may cover the biopsy area and make it harder for doctors to see where to continue the procedure. RDI is an imaging mode that uses special colors of light to help show blood-covered areas more clearly.The main question this study aims to answer is:Does RDI improve visibility of the bronchoscopic field after bleeding caused by bronchoscopic biopsy? Researchers will compare images taken with standard white light imaging and RDI during the same bronchoscopy procedure. Both types of images will be taken after the first biopsy and before any field-clearing treatment is done. Participants will have bronchoscopic biopsy as part of their regular medical care, have images taken using standard white light imaging and RDI during the same procedure, have routine follow-up for possible medical problems after bronchoscopy. Taking part in this study will not add extra biopsies or change the participant's regular medical care.
