CT image, 3D reconstruction image, and 3D model of the same case. a The patient’s two-dimensional (2D) computed tomography (CT) image showing a part-ground glass nodule (pGGN) in the left upper lung. b–e The patient’s three-dimensional (3D) CT reconstruction image, from which the lung veins, bronchus, and arteries can be more intuitive. f The patient’s 3D print of the lung model not only allows the visualisation of the lung anatomy but also facilitates coordinate positioning, accurately locates the lesion, and helps in the precise wedge resection of the lesion during surgery
