From: [18F]Fluoride uptake in various bone types and soft tissues in rat
a Time-activity curves (TACs) obtained from VOIs of different rat bones. b The TAC of the left cardiac ventricle demonstrates the rapid clearance of [18F]fluoride from blood. c Uptake in kidney and bladder represent excretion of [18F]fluoride via the urinary tract; the TAC for the tibia shows an example of [18F]fluoride uptake in the diaphysis of a long bone. LV = Lumbar vertebrae, CJ = costochondral joint. Values are the mean ± SD, n = 3–5
