Virtual bronchoscopy-guided bronchoscopic marking. a: Virtual bronchoscopy image created by Synapse Vincent (Fuji Film, Tokyo, Japan) to visualize the best path to reach the target pulmonary nodule. b: A thin bronchoscope was inserted into the peripheral bronchus based on the virtual bronchoscopy images. A transbronchial aspiration cytology (TBAC) needle enclosed within an outer sheath was advanced to the peripheral end of the bronchus until the operator could feel resistance. The outer sheath was retracted 3 cm, and 1 cm of the TBAC needle tip was exposed from the outer sheath. The TBAC needle and the outer sheath were advanced 1 cm to penetrate the lung parenchyma through the bronchial wall. The indocyanine green/iopamidol marking dye was injected through the TBAC needle into the lung parenchyma
