What is the highest dose organ for Tc tetrofosmin?

• A. Heart
• B. Liver
• C. Large intestines
• D. Kidneys

Answer: (C)

In the context of Tc tetrofosmin, the highest dose organ is actually the heart. Tc tetrofosmin is a radiopharmaceutical primarily used in myocardial perfusion imaging, where it is taken up by the myocardium in proportion to blood flow. The heart receives significant doses because of this concentrated uptake, which is essential for assessing cardiac function and perfusion. While there may be some radiation exposure to the liver, kidneys, and large intestines, the heart serves as the principal organ of interest for Tc tetrofosmin due to its design for cardiac imaging. Thus, understanding the pharmacokinetics of Tc tetrofosmin reveals that the heart is the organ receiving the highest radiation dose when this radiopharmaceutical is utilized in clinical practice.
