What is the brand name for Tc exametazime (HMPAO)?

• A. Nephroscan
• B. Ceretec
• C. Thallous Chloride
• D. Cardiolite

Answer: (B)

The brand name for Tc exametazime (HMPAO) is Ceretec. Tc exametazime is a radiopharmaceutical used primarily in brain imaging, particularly to assess cerebral perfusion. Ceretec is specifically designed for labeling with technetium-99m, which is widely used in nuclear medicine due to its favorable characteristics, such as its half-life and emission properties.

Ceretec allows clinicians to visualize areas of the brain that are functioning normally versus those that may be hypoperfused due to conditions like stroke or other cerebrovascular diseases. Its usage in the medical field underscores the importance of technetium-99m as a versatile and effective tracer in diagnostic imaging.

Other options like Nephroscan, Thallous Chloride, and Cardiolite refer to different radiopharmaceuticals used for various imaging purposes. Nephroscan is used for renal imaging, Thallous Chloride is utilized in myocardial perfusion imaging, and Cardiolite is used for cardiac imaging. Each of these has distinct compositions and applications, which differentiates them from Ceretec, confirming that Ceretec is indeed the correct answer for Tc exametazime (HMPAO).
