Internal Audit to Monitor the Injected Activity in PET/CT Using Control Charts.

Background And Objective: In an effort to limit the risks associated with medical radiation exposure, the last century witnessed the development of dose control mechanisms, recommended by the International Commission on Radiological Protection. This organization recommends the optimization of radiation protection to provide the highest level of safety that may reasonably be achievable. Adhering to the "as low as reasonably achievable" principle, the purpose of this study was to monitor the 18 F-FDG injected activity in PET and optimize the radiation protection through an internal audit process.
