Abstract：Objective Establish scientific and effective medical equipment support system and management measures, extend
the equipment service cycle, carry out reliability analysis and improvement of in-use Magnetic resonance imaging
equipment. Methods Failure mode effects and criticality analysis was used to analyze the in-use MRI equipment, and the expert
consultation method and analytic hierarchy process were combined to improve the risk priority number. Results The hazard degree
evaluation model of in-use MRI equipment was established, and the fault risk ranking of in-use MRI equipment was obtained by
using the improved risk priority coefficient evaluation method. Conclusion By prospectively considering the uncertainties of all
kinds of risks in the clinical use of magnetic resonance equipment and its influences on magnetic resonance equipment, effective
countermeasures are developed to provide support and guarantee for hospitals to effectively deal with all kinds of emergencies and
risks in the clinical use of magnetic resonance equipment in the operation and decision-making. To promote the hospital allocation of
resources, optimize the process, timely and appropriate, effective response to risk, improve the efficiency and effect of risk response.
