Bone turnover prediction in patients with chronic kidney disease (CKD) undergoing hemodialysis using shortened dynamic F-NaF PET/CT K-Patlak.

This study investigated whether K-Patlak derived from a shortened scan time for dynamic F-NaF PET/CT in chronic kidney disease (CKD) patients undergoing hemodialysis can provide predictive accuracy comparable to that obtained from a longer scan. Twenty-seven patients on chronic hemodialysis, involving a total of 42 scans between December 2021 and August 2023 were recruited. Dynamic F-NaF PET/CT scans, lasting 60-90 min, were immediately acquired post-injection, covering the mid-twelfth thoracic vertebra to the pelvis region.
