Which radiopharmaceutical is known to be light sensitive?

• A. Technetium-99m
• B. Mertiatide
• C. Gallium-67
• D. Iodine-123

Answer: (B)

Mertiatide, also known as [99mTc] MAG3, is recognized as a light-sensitive radiopharmaceutical. This characteristic means that exposure to light may degrade the compound, which could potentially affect its stability and efficacy in diagnostic imaging. Therefore, when handling mertiatide, it is important to protect it from light to ensure that it remains effective for use in procedures such as renal imaging. The other radiopharmaceuticals listed do not share this significant sensitivity to light. Technetium-99m is widely used in a variety of imaging studies, primarily because of its ideal physical properties; it is stable under normal conditions. Gallium-67 and Iodine-123, while having their own handling requirements, do not have strict light sensitivity concerns like mertiatide. Understanding the specific handling and storage requirements for different radiopharmaceuticals is crucial for maintaining their integrity and ensuring optimal diagnostic outcomes.
