What is a primary clinical application of Tc mertiatide (MAG-3)?

• A. Assessing liver function
• B. Measuring red blood cell mass
• C. Evaluating renal function
• D. Imaging cardiac perfusion

Answer: (C)

Technetium mertiatide, commonly referred to as MAG-3, is primarily used in the evaluation of renal function. This radiopharmaceutical is specifically designed for renal imaging, offering insights into kidney function and morphology by utilizing the principles of dynamic scintigraphy. MAG-3 is particularly effective in assessing glomerular filtration rate (GFR) and renal blood flow.

In practice, MAG-3 is administered to patients, and its distribution is monitored through gamma camera imaging to provide detailed information about the kidneys' ability to filter blood. The results from this imaging allow healthcare providers to diagnose various renal conditions, assess kidney transplant viability, and monitor changes in renal function over time.

This focused application is crucial for managing conditions affecting kidney performance, making it a key tool in nephrology and urology. The specific properties of Tc mertiatide that facilitate its use in renal imaging underscore its importance in clinical settings when evaluating patients for kidney-related issues.
