ROSE for Improved Molecular Marker Testing Via EBUS

This research study is being done to compare two ways to conduct bronchoscopic biopsy of lymph nodes and other structures in the chest (i.e. the presence or absence of an on-site cytotechnologist performing a limited microscopic evaluation to provide non-binding feedback on specimen adequacy in real time during the procedure).
