Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Positron-emitting radionuclide used for bone imaging; fluoride ion is incorporated into bone matrix via chemisorption onto hydroxyapatite crystals, reflecting blood flow and osteoblastic activity.
Xenoview is a paramagnetic contrast agent for MRI that enhances T1 relaxation by shortening the longitudinal relaxation time of water protons in tissues where it accumulates, thereby increasing signal intensity on T1-weighted images.
2-10 mCi (74-370 MBq) intravenous bolus injection, single dose for positron emission tomography (PET) bone imaging.
Not applicable (diagnostic agent, not therapeutic); refer to imaging protocol.

The terminal elimination half-life is approximately 2-4 hours. Clinically, this allows for imaging within 1-3 hours post-injection.
Terminal elimination half-life is 3-5 hours in patients with normal renal function; may be prolonged in renal impairment.
Renal (primarily). Approximately 70% of the administered dose is excreted unchanged in urine within 24 hours. Less than 10% is excreted in feces.
Primarily renal excretion (60-70% unchanged drug), with 20-25% biliary/fecal elimination.
