"A part-solid lung nodule (PSN) is a subtype of subsolid lung nodule. The term refers to a ground-glass nodule which contains one or more solid components with attenuation similar to a pulmonary vessel on non-contrast CT. High-resolution CT is necessary for analysis and AI promises improved characterisation."

"Around one quarter of PSNs are inflammatory and resolve on follow-up imaging 11. Ill-defined foci of infection or inflammation may contain a solitary solid component 12. Persistent part-solid nodules are commonly malignant 11 but may be indolent and require extended follow-up for 5 years or more. Li reports that malignant PSNs tend to be well-defined, lobulated and contain irregular scattered solid components 12. The risk of malignancy increases with nodule size."
