Comparison of 18F-FDG-PET-CT and bone scintigraphy for evaluation of osseous metastases in newly diagnosed and recurrent osteosarcoma

摘要

BackgroundBone scintigraphy (BS) is used to detect osseous metastases in osteosarcoma. ¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography (¹⁸F-FDG-PET-CT) is being increasingly used for staging. We compared the sensitivity, specificity, and diagnostic accuracy of ¹⁸F-FDG-PET-CT and BS for detecting osseous metastases in osteosarcoma.
