医用磁共振成像设备临床需求调研及发展趋势分析
|
摘要
目的调查我国不同等级医院磁共振从业人员在临床及科研工作中对医用磁共振设备的需求情况,为国产磁共振设备的发展提供参考和理论依据。材料与方法由多名影像诊断医师、医学工程师及统计学专家组成专家小组,运用Delphi法研究拟定《医用磁共振临床需求调查表》,通过问卷星平台发布问卷,对我国不同等级医院的磁共振从业人员进行临床需求调查。结果 2018年9月至2018年11月,共计回收来自我国21个省市的有效问卷246份。磁共振设备场强需求分析表明,1.5 T和3.0 T MRI设备需求最高,占比分别为74.2%和77.9%,而1.0 T及以下低场MRI设备需求较低,仅占不到5%。临床医师在诊断、科研、未来趋势设备及技术3个方面需求均较高,其中一级需求指标25项,二级需求指标29项。结论中高端磁共振设备在临床诊疗和科研中需求较高,国产磁共振设备厂家应基于用户具体需求进行产品定位及技术研发。
Objective: To investigate the clinical demand of medical magnetic resonance imaging(MRI) from radiologists of different grades of medical institutions in China, so as to provide reference and theoretical foundation for the development of domestic MRI equipment. Materials and Methods: The clinical MRI demand questionnaire was optimized by the panel of experts comprised of radiologists, medical engineers and statisticians using Delphi method. The survey of clinical demand was carried out online(https://www.sojump.com/) with MRI users working in different grades of hospitals in China. Results: A total of 246 valid feedbacks from 21 provinces were collected from September to November, 2018.The survey of magnetic field strength requirements showed that 1.5 T and 3.0 T MRI were mostly demanded, with the percentage of 74.2% and 77.9% respectively. Less than 5% of the participants had the demand for MRI equipment with magnetic field strength under 1.5 T25 first-level demand indicators and 29 second-level demand indicators were extracted from perspectives of clinical diagnosis, scientific research and prospective equipment. Conclusions:The medium and high-end MRI equipment are highly demanded among MRI users. Domestic MRI equipment manufacturers should conduct product positioning and technical research and development based on the specific demands of MRI users.
