Incidental skeletal findings on Sodium-Fluorine (NaF) PET: A collection of benign tumors

Sodium-Fluoride PET is a sensitive method to detect altered bone mineralization. Its increasing use in routine clinical practice for metastatic bone disease has also resulted in the detection or characterization of incidental benign bone lesions. A spectrum of NaF PET scan cases with benign bone tumors are presented in this article, including whole body PET bone scan and selected PET/CT, CT or MR images of the region of interest. By reviewing these cases, the reader will be able to improve the knowledge related to the clinical presentation of these entities, some of them rare, and to recognize them based on NaF PET and CT/MR imaging patterns.
