[ 18 F] Sodium Fluoride PET Kinetic Parameters in Bone Imaging.

This report describes the significance of the kinetic parameters (k-values) obtained from the analysis of dynamic positron emission tomography (PET) scans using the Hawkins model describing the pharmacokinetics of sodium fluoride ([ 18 F]NaF) to understand bone physiology. Dynamic [ 18 F]NaF PET scans may be useful as an imaging biomarker in early phase clinical trials of novel drugs in development by permitting early detection of treatment-response signals that may help avoid late-stage attrition.
