This leads to hypercalcemia, resulting in osteoporosis and eventually the formation of \u201cbrown tumors.\u201d Currently used radiological and nuclear medicine imaging for primary hyperparathyroidism face challenges in accurately diagnosing bone-related complications. Molecular bone imaging techniques routinely consist of bone scintigraphy, with possible addition of bone-SPECT\/CT. Recently, renewed interest has emerged in the use of Na[<jats:sup>18<\/jats:sup>F]F-PET\/CT. Both applications are highly sensitive to <jats:italic>in vivo<\/jats:italic> osteoblast activity. However, the latter technique offers improved spatial resolution and sensitivity, as well as shorter incubation and faster scanning. This article summarizes current limitations and potential improvements in bone-SPECT\/CT and Na[<jats:sup>18<\/jats:sup>F]F-PET\/CT imaging in selected patients with hyperparathyroidism, compared to other relevant techniques and clinical parameters.<\/jats:p>","DOI":"10.3389\/fnume.2025.1565906","type":"journal-article","created":{"date-parts":[[2025,4,16]],"date-time":"2025-04-16T05:26:53Z","timestamp":1744781213000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Use
