Nodule aspect and malignancy
| Aspect | Samples | SUVmax >2.5 | SUVmax <2.5 | Malignant nodules | Benign nodules |
| Solid | 64 | 48 (75%) | 16 (25%) | 54 (84%) | 10 (16%) |
| Subsolid | 41 | 29 (71%) | 12 (29%) | 38 (93%) | 3 (7%) |
Data are presented as n or n (%). Subsolid aspect was more associated with malignancy than solid nodules, even when the latter were characterised by greater SUVmax values.
