HD+ I-scan Bronchoscopy Vascular Abnormalities Detection Multicenter Study

"3 different types of bronchoscopy image settings will be used investigating the entire bronchial tree.~When sites with abnormal or suspicious vascular patterns are detected meeting the criteria of abnormality \[visual scale adapted from Herth 2009 and Zaric 2013\] the investigator will change to a normal bronchoscope and take biopsies from each site and a biopsy from a normal secondary carina on the contralateral site as control."
