Fig. 4From: Ground glass pulmonary nodules: their significance in oncology patients and the role of computer tomography and 18F–fluorodeoxyglucose positron emission tomographyExamples of PET/CT imaging. (a) A 75 year-old man with a previous history of colon-rectal cancer. A CT imaging showed a sub-solid lung nodule (diameter of pars-solid was 9 mm). FDG PET/CT was negative. After 18 months of follow-up, the nodules disappeared. (b) A 72 year-old man with a previous prostate cancer treated with hormonal therapy from 2007. In 2010, CT imaging revealed a sub-solid lung nodule. PET/CT demonstrated a significant uptake of FDG in the solid component of the nodule. The histopathological analysis was definitive for a lung adenocarcinomaBack to article page
