INDIUM IN 111 CHLORIDE vs SODIUM FLUORIDE F-18
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Indium In 111 chloride is a radiopharmaceutical that emits gamma radiation. It binds to transferrin in the blood and is taken up by certain cells, allowing imaging of the reticuloendothelial system or labeled cells.
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.
Intravenous administration of 1.0 mCi (37 MBq) for routine imaging; dose may range from 0.5 to 2.0 mCi (18.5 to 74 MBq) depending on imaging protocol.
2-10 mCi (74-370 MBq) intravenous bolus injection, single dose for positron emission tomography (PET) bone imaging.

Physical half-life: 2.804 days (67.3 hours). Biological half-life: 50-100 days for retained fraction. Effective half-life (combined): ~2.7 days for early phase, prolonged for bone marrow.
The terminal elimination half-life is approximately 2-4 hours. Clinically, this allows for imaging within 1-3 hours post-injection.
Renal (90% over 48 hours), fecal (<1% as unchanged). The remainder is retained in organs (liver, spleen, bone marrow) with slow release.
Renal (primarily). Approximately 70% of the administered dose is excreted unchanged in urine within 24 hours. Less than 10% is excreted in feces.
