目的 评估医联体内远程胸部DR图像质量及其影响因素。方法 在华医民生影像中心远程影像诊断系统中,选取其围场县医学影像诊断基地2017-01至2018-05的胸部后前位DR图像,每个月随机选取20例进行评分,评分标准为欧洲共同体组织(CEC)出版的《放射诊断摄影影像的质量标准》。同时收集每例患者摄片时的设备及人员信息,分析影响DR图像的因素。结果 加入医联体后,DR图像质量随着时间的延长评分质量越来越高;各项评分标准中,第1、2、3、10项评分较低;多因素线性回归分析显示图像质量改善与加入医联体的时间长度相关(β=0.32,P<0.05)。结论 加入医联体后,图像质量均得到改善,图像质量改善与加入医联体的时间长度相关。

Objective To evaluate the quality of chest DR and its influencing factors during remote imaging diagnosis in collaboration with Huayi Minsheng Imaging Center.Methods In the remote imaging diagnosis system of Huayi Minsheng Imaging Center, 20 patients were randomly selected each month between January 2017 and May 2018 at the medical imaging diagnosis base of Weichang County to score the chest posterior-anterior DR images according to the “Guidelines on Quality Criteria for Diagnostic Radiographic Images” published by the Commission of the European Community (CEC). At the same time, the information on the equipment and each patient was collected while the factors that influenced DR images were analyzed.Results After joining the medical association, the DR image quality was improved compared with the first quarter(P<0.05). Multivariate linear regression analysis showed that the improvement of image quality was related to how long it was since joining the medical association(β=0.32, P<0.05).Conclusions The image quality is improved after joining the medical association, and the extent to which the image quality is improved is related to how long it is since joining the medical association.
