(A) Chest CT before marking. The lesion (arrow, 10 mm in size and 8-mm depth from the visceral pleura) locates in the right lower lobe. (B) Chest high-resolution CT during marking. The TBAC needle without its tip inserted through the biopsy channel of the videobronchoscope (arrow) was positioned to the proximal site of the lesion under CT guidance. (C) Chest CT after marking. Barium sulfate of 0.5 mL of 100 w/v% (thick arrow) is instilled at the central side of the lesion (thin arrow).

Intraoperative fluoroscopic imaging. The nodule with barium sulfate marking, which is grasped in the forceps, is resected by an endostapler under both fluoroscopic and thoracoscopic guidance. Because the marker locates at the central side of the lesion, resection of the marker means complete removal of the lesion (E = endostapler; F = forceps).
