对国产永磁型磁共振成像设备进行卫生技术评估，为政府制定公共卫生政策、产业发展规划、技术创新指南提供科学依据。采用公开文献、企业调查、医院问卷等方式，对某家国产永磁型磁共振成像设备的图像质量、安全性能、有效性、利用率、经济性、社会性等六方面进行评价。结果显示该型设备图像质量和安全性能符合技术标准；诊断检查多数比CT、MSCT、US、X线等检出率高；设备使用率达到95%以上，适合各级别医院使用，尤其是二甲医院；成本-效益远高于进口同类设备；社会已有较好的认可度。%A domestic permanent magnet magnetic resonance imaging (MRI) was evaluated by health technology assessment (HTA) so as to provide the scientiifc basis for the public health policies, the industrial development planning, and the guide of technological innovation for China government. The paper assessed the image quality, safety, effectiveness, efficiency, economy, sociality of the domestic MRI equipment by analyzing data from the public literature and surveys to the company and hospital. Results showed that image quality and safety performance of the MRI met technical standards; the relevance ratio of diagnostic was more than that of CT, MSCT, US and X-ray; utilization rate of the MRI was above 95%, which made it suitable for hospitals at all levels, especially second senior-class hospitals. And the cost-beneift was much higher than similar imported equipment.
