What is the appearance of FDG during quality control?

The appearance of FDG (fluorodeoxyglucose) during quality control is expected to be a clear liquid that is free of particles. This is crucial for ensuring the integrity and safety of the radiopharmaceutical before it is administered to patients. A clear liquid indicates that the solution is properly formulated and has not undergone any degradation or contamination that could compromise its efficacy or safety. During quality control, visual inspection is an important step, and any abnormalities such as cloudiness, discoloration, or visible particulates may indicate problems that would require further investigation. The maintenance of these quality parameters is essential in the context of PET imaging, as impurities or inconsistencies can affect the imaging results and patient outcomes.
