Advances in the prediction of spread through air spaces with imaging in lung cancer: a narrative review.

STAS is an important invasion type of lung cancer, affecting the survival prognosis of patients. Preoperative CT and F-FDG PET/CT have certain value in predicting the status of STAS, assisting clinicians in selecting an optimal surgical approach and postsurgical treatment. The prediction of STAS based on radiomics and DL can represent a future research direction.
