Superiority of NaF PET/CT Over Chest CT in a Case of Osteosarcoma.

ABSTRACT We report the case of a 21-year-old man referred to our institution for the initial staging of an osteoblastic osteosarcoma of the right femur. An 18F-NaF PET/CT demonstrated millimetric pleuroparenchymal metastases, later confirmed on follow-up. These lesions were not reported on both dedicated chest CT and 18F-FDG PET/CT.
