Reprint requests to: publications@acr.org Primary Bone Tumors The recommendations for all variants in this document apply to the following body regions: lower extremity, upper extremity, ribs, pelvis, skull, and spine. Discussion of Procedures by Variant Variant 1: Suspect primary bone tumor. Initial imaging. CT Area of Interest CT is not routinely used in the initial evaluation of primary bone tumors. There is no relevant literature regarding the use of CT in the initial imaging of primary bone tumors. FDG-PET/CT Whole Body PET using the tracer fluorine-18-2-fluoro-2-deoxy-D-glucose (FDG)/CT is not routinely used in the initial evaluation of primary bone tumors. There is no relevant literature regarding the use of FDG-PET/CT in the initial imaging of primary bone tumors. MRI Area of Interest MRI is not routinely used in the initial evaluation of primary bone tumors. There is no relevant literature regarding the use of MRI in the initial imaging of primary bone tumors. Radiography Area of Interest Radiographs remain the most appropriate imaging modality for screening and initial characterization of primary bone tumors. Radiographs provide an accurate means by which to evaluate primary bone tumors. Radiographs effectively provide information in regard to tumor location, size, and shape, as well as evidence of tumor biological activity [3]. Tumor margin and periosteal reaction provide a reliable index of biological potential of the tumor, whereas matrix, if identified, is a key to the underlying histology [3-6].
