医用超声设备浅表基础成像图像质量对比评价

Comparative Evaluation of Image Quality of Superficial Basic Imaging of Medical Ultrasonic Equipment

目的为比较国产与进口医用超声设备浅表基础图像的质量,本课题进行了全国多区域医院的医用超声成像系统的综合评价。方法本研究分析包括上海市在内的全国5家医院209例受试者的浅表超声基础图像资料。受训者对同一名受试者的浅表同时行国产和进口设备的检查,检查完成后图像上传至数据系统。结果采用李克特评分,评分采用Wilcoxon秩和检验进行统计学分析。结果比较国产与进口设备的浅表基础图像质量,大部分切面中二者评分的差异无统计学意义。部分国产品牌基础图像的评分较高,部分切面的评分高于进口设备,主要表现在彩色多普勒功能、细节分辨力方面,差异有统计学意义。结论通过国产与进口医用超声设备的比较研究,可客观了解目前国产医用超声设备浅表基础图像质量的优劣,为国家提供国产医用超声设备发展战略的依据和支撑。

Objective To compare the quality of superficial basic images of domestic and imported medical ultrasound equipment,this study conducted a comprehensive evaluation of the medical ultrasound imaging system in multi-regional hospitals across the country.Methods The basic superficial ultrasound image data of 209 subjects in 5 hospitals including Shanghai were analyzed.The trainee was inspected the superficial surface of the same subject simultaneously with the domestic and imported equipment.After the inspection,the image was uploaded to the data system.Results was scored with Likert scale and Wilcoxon rank sum test was used for statistical analysis.Results Comparing the superficial basic image quality of domestic and imported equipment,the difference between the two scores in most sections was not statistically significant.The scores of some basic images of domestic brands were higher,while those of some sections were higher than those of imported devices,which were mainly reflected in color doppler function and detail resolution,with statistically significant differences.Conclusion Through the comparative study of domestic and imported medical ultrasonic equipment,we can objectively know the advantages and disadvantages of the superficial basic image quality of the domestic medical ultrasonic equipment,and provide the basis and support for the development strategy of domestic medical ultrasonic equipment.
