Tracers are prepared in clean and protected environments... and administered ________

• A. Intravenously
• B. Orally
• C. Intramuscularly
• D. Subcutaneously

Answer: (A)

Sterile preparation and the route of administration determine how reliably a radiopharmaceutical tracer behaves in the body. Intravenous administration is the standard because it delivers the tracer directly into the bloodstream, giving rapid, uniform distribution and predictable pharmacokinetics. This allows accurate imaging and precise dosing, which are essential for high-quality diagnostic results. Oral administration can cause variable absorption and first-pass effects, and many tracers aren’t well absorbed or remain unstable in the gut. Intramuscular and subcutaneous routes lead to slower, inconsistent absorption, making them unsuitable for most tracers. That’s why intravenous delivery is the best and most consistent choice.
