目的探讨尘肺病普查中DR胸片与高千伏胶屏胸片的综合应用。方法随机选择2011年3—11月在我院普查的452接触粉尘人员,采用DR拍摄技术和胶屏高千伏拍摄技术进行胸片拍摄,对二组胸片的拍摄及后期处理时间,照片质量、分布范围、总体密集度、尘肺分期进行对比。结果 DR胸片人均拍摄时间约2.2min,胶屏高千伏胸片人均拍摄时间约3.5min;DR胸片优片:399张,优片率:88%,胶屏高千伏胸片优片:213张,优片率:47%。结论在尘肺病的普查中,较为理想的模式应该是以DR胸片为主要手段,对接触粉尘史可疑受检者及DR胸片可疑受检者,再进行胶屏高千伏胸片检查。从成本和时间的角度加大对尘肺病普查的覆盖面,提高尘肺病普查效率,又能在符合国家法律的基础上,保证对尘肺病患者的诊断准确度。
Objective To investigate the comprehensive application of DR chest radiograph and high KV radiographic chest radiography in pneumoconiosis survey. Methods 452 contact dust personnel randomly selected from March to November in 2011 in our hospital were selected to carry out radiographs of chest radiographs by using DR shooting technique and plastic high-kv filming technique. The radiographs of the two groups of chest radiographs, the post-processing time, the photo quality , Distribution range, the overall intensity, pneumoconiosis staging comparison. Results DR chest filming time per capita about 2.2min, plastic high kV chest film per capita recording time of about 3.5min; DR chest film excellent piece: 399, excellent film rate: 88% : 213, excellent film rate: 47%. Conclusion In the screening of pneumoconiosis, the ideal model should be DR chest film as the main means of contact with the suspicious history of dust and DR chest suspected suspect subjects, and then plastic high kV chest X-ray examination. From the perspective of cost and time, it is necessary to increase the coverage of the pneumoconiosis survey and improve the screening efficiency of pneumoconiosis. In addition, the diagnostic accuracy of pneumoconiosis patients can be guaranteed on the basis of complying with national laws.
