Fig. 3.

Examples of nodules with variation between the longest diameter, mean diameter based on volumetry, and mean of longest and perpendicular diameter. Each row depicts a nodule, displayed in the axial (left) and coronal (right) plane and centered in the images with a field of view of 60 x 60 mm. (A) Benign solid nodule with D^longest-C 7.8 mm, D^mean3D 5.3 mm, D^meanAxial 6.3 mm; (B) Malignant part-solid nodule with D^longest-C of total nodule 16.6 mm and of solid component 13.3 mm, D^mean3D of total nodule 12.3 mm and of solid component 7.4 mm, D^meanAxial of total nodule 15.0 mm and of solid component 10.6 mm; (C) Benign pure ground-glass nodule with D^longest-C 20.6 mm, D^mean3D 13.0 mm, D^meanAxial 17.0 mm
