Which method is preferred for the administration of Tc tilmanocept for lymphatic imaging?

• A. Oral ingestion
• B. Intramuscular injection
• C. Intradermal or subcutaneous injection
• D. Intravenous bolus

Answer: (C)

The preferred method for the administration of Tc tilmanocept for lymphatic imaging is intradermal or subcutaneous injection. This route is specifically designed to enhance the visualization of lymphatic anatomy and function. When injected intradermally or subcutaneously, Tc tilmanocept is able to effectively target lymphatic tissues, allowing for optimal distribution and uptake in the lymph nodes. This method is advantageous because it provides a localized administration that leads to better lymphatic sensitivity, thereby facilitating clearer imaging. The intradermal or subcutaneous route ensures that the radiopharmaceutical is in close proximity to the lymphatic vessels, which is essential for accurate lymphatic imaging. In contrast, oral ingestion would not provide the necessary localization to the lymphatic system, as the substance would undergo gastrointestinal absorption, thus negating the intended imaging effects. Intramuscular injection may disperse the agent too broadly without focusing on the lymphatic pathways. An intravenous bolus could lead to a rapid distribution throughout the bloodstream rather than localized lymphatic uptake. Therefore, intradermal or subcutaneous injection remains the most effective choice for this specific application in lymphatic imaging.
