PET/MR is a high-end medical imaging equipment with integrating PET and MR equipment into the highly
sophisticated one and has rich clinical and molecular diagnosis functions, can obtain comprehensive information
about the human body structure, function and metabolism, is of great value for the diagnosis and treatment of disease
improvement. In this paper, through the analysis of existing production risk points on one of the primary stages of the
whole product life cycle, combining with the medical device good manufacture practice, some suggestions have been
put forward exploratively to field inspection for PET/MR manufacturers. It has certain significance for regulators of
medical devices to clear the production risk point and improve verification efficiency during field inspection.
