description | In a healthy body, homeostatic actions of osteoclasts and osteoblasts maintain the integrity of the skeletal system. When cellular activities of osteoclasts and osteoblasts become abnormal, pathological bone conditions, such as osteoporosis, can occur. Traditional imaging modalities, such as radiographs, are insensitive to the early cellular changes that precede gross pathological findings, often leading to delayed disease diagnoses and suboptimal therapeutic strategies. <sup>18</sup>F-sodium fluoride (<sup>18</sup>F-NaF)-positron emission tomography (PET) is an emerging imaging modality with the potential for early diagnosis and monitoring of bone diseases through the detection of subtle metabolic changes. Specifically, the dissociated <sup>18</sup>F<sup>-</sup> is incorporated into hydroxyapatite, and its uptake reflects osteoblastic activity and bone perfusion, allowing for the quantification of bone turnover. While <sup>18</sup>F-NaF-PET has traditionally been used to detect metastatic bone disease, recent literature corroborates the use of <sup>18</sup>F-NaF-PET in benign osseous conditions as well. In this review, we discuss the cellular mechanisms of <sup>18</sup>F-NaF-PET and examine recent findings on its clinical application in diverse metabolic, autoimmune, and osteogenic bone disorders. |
