What is the brand name for Tc tetrofosmin?

• A. Cardiolite
• B. Myoview
• C. Miraluma
• D. TechneScan

Answer: (B)

Tc tetrofosmin is a radiopharmaceutical used primarily in myocardial perfusion imaging to evaluate heart function and blood flow. Its brand name is Myoview, which is specifically designed to visualize the heart’s viability and perfusion due to its ability to mimic the natural uptake of the heart muscle.

Myoview is preferred in nuclear medicine due to its favorable pharmacokinetics and imaging characteristics, allowing for clear visualization of the cardiac tissue. This imaging technique can help in identifying areas of the heart that may not be receiving adequate blood flow, which is critical for diagnosing various cardiac conditions.

Other choices, such as Cardiolite and TechneScan, correspond to different radiopharmaceuticals used for similar or different diagnostic evaluations, yet they do not represent Tc tetrofosmin. Cardiolite, for example, contains a different radiopharmaceutical (sestamibi), while TechneScan references a broader range of Tc-based imaging agents. Miraluma, on the other hand, is related to imaging for breast cancer and does not pertain to myocardial perfusion imaging. Thus, Myoview is the accurate brand name associated specifically with Tc tetrofosmin.
