MRI远程质量控制核心评价指标体系构建及实证研究OA

Objective To construct a core evaluation index system for remote quality control of magnetic resonance imaging(MRI)and apply it to empirical research on MRI remote quality control work.Methods The key elements of MRI remote quality control evaluation were systematically analyzed through literature analysis,unstructured interview,and Delphi method to construct a core evaluation index system.Data of each index in hospital MRI remote quality control from 2022 to 2023 were collected,and the evaluation was conducted using the entropy weight-based technique for order preference by similarity to ideal solution(TOPSIS).Meanwhile,the results were compared with those of clinical photo evaluation in MRI quality control.Results A core evaluation index system for MRI remote quality control was constructed,covering 4 first-level indicators(environmental parameters,radiofrequency system,magnet system,and image performance)and 15 second-level indicators.In addition,empirical research showed that the evaluation results of the entropy weight TOPSIS method were basically consistent with those of the clinical photo evaluation method(Pearson correlation coefficient ρ=0.78).Conclusion The core evaluation index system for MRI remote quality control constructed in this study has effectiveness,objectivity,and practicability.It provides new ideas and methodological tools for digital and refined quality management of medical equipment,and the popularization and application of this system is expected to play an important role in improving the management efficiency of medical equipment.
