From: [18F]Fluoride uptake in various bone types and soft tissues in rat
Individual kinetic values derived from a model of [18F]fluoride uptake for different rat bones. a K1: describes bone perfusion; b Ki: reflects bone osteoblastic activity; c Ki/K1: describes the efficiency of unidirectional extraction from blood to bone; and d k3: the rate constant from the extravascular compartment to the bone bound compartment. Values are based on measurements in 1–3 male rats. Different symbols represent different rats. LV = lumbar vertebrae, CJ = costochondral joint
