Fig. 1

A series of computed tomography images of a squamous cell carcinoma with ground glass nodule. a Chest computed tomography (CT) image showing a 7-mm ground glass nodule (GGN) in the right lower lobe when the lesion was first noted. b Chest CT, obtained 1 year after a; the GGN has enlarged to 18 mm. c Chest CT image obtained 1.5 year after a; the GGN has enlarged to 24 mm and a solid component has developed. d In a semi-automated three-dimensional volumetric “GGN analysis” of c, the ground glass opacity component (green area, between −800 and −301 Hounsfield units) accounted for 64% of the tumor in contrast to the remaining solid component (purple area,  −300 Hounsfield units)
