Is [18F] fluoro-d-glucose PET combined with computed tomography useful for staging of T1 lung cancer with pure solid morphology? How much and how far?

[18F]FDG PET/CT is useful for staging of pure solid T1 lung cancer with a detection rate of 26% for lymph node metastases and 12% for distant metastases. [18F]FDG PET/CT is more accurate and has a higher positive predictive value than chest ceCT and leads to a change in the TNM stage in 17% of patients. Due to the limited sensitivity of FDG PET/CT in detecting lymph node metastases, lymphadenectomy cannot be omitted even in small pure solid T1 lung cancer.
