During quality control of a radiopharmaceutical, what is the acceptable percentage for mapping?

In the context of quality control for radiopharmaceuticals, the acceptable percentage for mapping is set at 90%. This parameter is critical for ensuring the reliability and safety of radiopharmaceuticals used in diagnostic and therapeutic procedures. Mapping refers to the evaluation of the distribution of radioactivity within the pharmaceutical to ensure it meets predetermined specifications.

Achieving a mapping percentage of 90% indicates that the majority of the administered radioactivity is located in the intended area within the product, which is essential for producing consistent and accurate diagnostic or therapeutic results. If the mapping falls below this percentage, it may signal issues such as improper formulation, distribution, or delivery of the radiopharmaceutical.

Standards in radiopharmacy are strict because they directly affect patient safety and the effectiveness of medical procedures. Thus, 90% is established as a benchmark that balances acceptable variability while maintaining the necessary precision required for medical applications.
