我国医用磁共振成像设备性能需求调查研究
|
摘要
目的:调研分析我国磁共振成像(MRI)从业人员对MRI设备性能的需求,为国产MRI设备厂商提高产品质量提供参考。方法:运用Delphi法制定"医用磁共振设备性能需求调查表",于"问卷星"网络平台发布问卷,从磁体、射频线圈、扫描床、计算机及后处理系统和设备稳定性5个维度对我国不同地区、不同等级医院的MRI从业人员进行调研。结果:回收来自全国21个省份不同等级医院的有效问卷246份,其综合分析显示,MRI从业人员对磁场均匀性及稳定性、患者摆位便捷性及射频线圈轻便性、扫描床移动便捷性及纵向移动范围、影像归档及传输系统(PACS)兼容性和操作便捷的后处理软件界面等指标的需求最高;设备稳定性每月设备可用率和平均故障间隔时间最受用户关注;Windows10系统、中文操作系统更受用户青睐。结论:医用MRI设备的改进应以用户需求为导向,不断提高MRI设备软硬件性能和使用便捷性,从而提升设备的整体品质。
Objective: To investigate and analyze the demand of MRI practitioners for equipment performance of medical magnetic resonance imaging(MRI) in China, so as to provide reference for domestic equipment manufacturers of MRI to improve product quality. Methods: "The Equipment Performance Demand Questionnaire of medical MRI" was formulated using Delphi method. The questionnaire was released online by internet platform(questionnaire star, https://www.sojump.com/) to implement investigation for MRI practitioners in hospitals of different districts and levels in China. Results: A total of 246 valid feedbacks from hospitals with different grads of 21 provinces were received. The comprehensive analysis indicated that the highest demanded indicators of MRI practitioners were as follows: the homogeneity and stability of magnetic field, positioning convenience of patients, portability of radio frequency coil, convenience of moving the scanning bed, the range of longitudinal shift of the scanning bed, the compatibility of picture archiving and communication systems(PACS), the convenience of post-processing software interface. Besides, the stability of MRI equipment, availability rate of monthly equipment and mean time between failures were most concerned by MRI users. Windows 10 and Chinese operating systems were more demanded by MRI users. Conclusion: The improvement of medical MRI equipment should be guided by the demands of users so as to constantly improve the performance of software and hardware of MRI equipment and its operational convenience, thereby it improves the overall quality of the MRI equipment.
