What is the maximum elution volume specified for stopping the use of the CardioGen-82® generator?

The correct answer is based on the operational guidelines for the CardioGen-82® generator, which is used for producing Rubidium-82 (Rb-82) for PET imaging. The maximum elution volume specified for when to stop using the generator is 17 liters. This threshold is set to ensure that the generator is used efficiently and safely, as exceeding this volume could lead to diminished performance, decreased radionuclide purity, and increased residuals that could complicate subsequent elutions.

Understanding this volume is critical for maintaining the quality of the imaging agent produced and ensuring patient safety. It helps ensure that the generator operates within its optimal range and provides reliable performance, which is essential in clinical settings.

The specified maximum elution volume reflects the generator's design and engineering limitations, emphasizing the importance of adhering to manufacturer guidelines to maintain the integrity of the cardiac imaging process.
