摘要
目的评价影像大数据在影像科CT质控管理和提高工作效率中的应用价值。方法应用大数据软件teamplay,共采集2017年9—12月共4个月的胸部CT扫描协议和胸部CT辐射剂量等相关数据,进行综合的整理和分析。结果不同的品牌设备,相同的扫描参数CT扫描协议的命名不同;同一品牌设备相同的扫描参数也有不同命名的协议。统计胸部平扫15万次辐射剂量DLP均值292.11 mGy·cm,中值260.40 mGy·cm。我院5千次扫描的中值129 mGy·cm。结论医学影像大数据能够为影像科CT的日常质控、管理提供有益的帮助。
Objective To evaluate the application value of big data in CT quality control management and improvement of work efciency in imaging department. Methods Using big data software teampilay, four months of chest CT scanning protocol and chest CT radiation dose data from September to December 2017 were collected, and made a comprehensive analysis. Results Diferent brands of equipment had diferent names for the same scanning parameters and CT scanning protocols. The same scanning parameters for the same brand of equipment also had diferent naming protocols. Statistics showed that the average DLP dose was 292.11 mGy·cm and the median was 260.40 mGy·cm for 150 000 times of chest plain scan. The median value of 5 000 scans in our hospital was 129 mGy·cm. Conclusion Medical imaging big data can provide useful help for routine quality control and management of CT in imaging department, and can also provide accurate medical imaging data for clinic
