Abbreviations
- Solitary pulmonary nodule (SPN)
- Ground-glass nodule (GGN)
Definitions
- Nodule: Single, focal spherical or ovoid opacity ≤ 3 cm
- Solid: Soft tissue attenuation
- Ground-glass (nonsolid): Visualization of parenchymal structures through nodule
- Part-solid (semisolid): Solid and ground-glass components
- Subsolid: Includes ground-glass and part-solid nodules
- SPN may be earliest imaging manifestation of lung cancer
- Nodule: Single, focal spherical or ovoid opacity ≤ 3 cm
