A representative case of indocyanine green virtual-assisted ling mapping (ICG-VAL-MAP). A, Target nodule located in the right upper lobe had ground-glass opacity (white arrow). B, Marking with ICG and computed tomography (CT) contrast agent located close to the nodule is observed as an obvious consolidation on CT scan after virtual-assisted lung mapping (VAL-MAP) (black arrow). C and D, Intraoperatively, the marking is easily identifiable in green on near-infrared thoracoscopy (C), but is not identifiable under visible light (D).
