How is Tc succimer (DMSA) administered?

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

Answer: (C)

Tc succimer (DMSA) is administered intravenously. This mode of administration is essential because intravenous delivery allows for rapid distribution of the radiopharmaceutical throughout the body, facilitating immediate imaging and diagnostic evaluation. Intravenous administration ensures that the agent reaches the target organs effectively, which is crucial for accurate imaging and assessment in nuclear medicine procedures.

Moreover, since Tc succimer is used primarily for renal imaging and evaluation, intravenous administration allows for clear visualization of the kidneys and their function. This is particularly important in assessing conditions like renal tumors, obstructive uropathy, and other renal pathologies, as it yields high-quality imaging results required for accurate diagnoses.
