A 77-year-old-woman with a part-solid ground-glass nodule that was diagnosed as adenocarcinoma by computed tomography-guided biopsy underwent robotic left upper segmentectomy. a A 23G needle was inserted into the lung parenchyma as close as possible to the nodule. b Five milliliters of a 4:1 mixture of dye indigo carmine and iopamidol was injected. c Images taken during robotic- surgery, showing 1 area in the left upper lobe that was clearly stained after computed tomography fluoroscopy-guided dye localization. d Intravenous indocyanine green delineation of the intersegmental plane between the lingula and left upper lobe segments illuminated by the Firefly
