The quantification strategy of solid component within a representative part-solid nodule. A 56-year-old male patient with nonmucinous invasive pulmonary adenocarcinoma (Grade 2) in right upper lobe. A, Lung window setting reveals a part-solid nodule. B, Manual and 2-dimensional measurement of consolidation/tumor ratio (CTR) basing on the maximal diameters of nodule and solid component. C, Automatic segmentation and greyscale discretization of nodule (attenuation threshold ranges from − 400 to 50 HU, step = 50 HU). D, 3-dimensional histogram and measurement of consolidation/tumor ratio of volume (CTRV) at attenuation threshold of -250 HU basing on the volumes of nodule and solid component
