Bronchoscopic microsampling (BMS) procedure. The BMS probe consists of a polyethylene outer sheath (black arrowhead) and an inner cotton fiber rod probe attached to a 30-mm-long stainless steel guide wire (white arrowhead). The probe is guided to the affected lesion in the subsegmental bronchus thorough the bronchoscope channel and the inner fiber rod probe (white arrowhead) is placed on the bronchial membrane as near as possible to the lung nodule.
