煤矿工人肺尘埃沉着病普查的影像学分析

目的总结煤矿工人肺尘埃沉着病发病的特点和规律，为肺尘埃沉着病的预防、诊断及治疗提供必要的依据。方法对某煤矿2013年486例煤矿工人进行肺尘埃沉着病普查，对普查胸片质量及胸片的影像学表现（包括小阴影形态，密集度及分布部位）进行统计分析。结果此次普查胸片优良率为89．7％（436／486），在检出的26例确诊病例中共发现67个肺区有小阴影存在，以P、q影为主，占91．0％（61／67），小阴影分布以两中下肺区为主，占83．6％（56／67），确诊病例总体密集度以1级为主，占88．5％（23／26）。结论优良的胸片是确诊肺尘埃沉着病的影像学基础，煤工肺尘埃沉着病X线胸片小阴影的影像学特征具有一定的规律性，通过普查胸片早期发现患者和高危人群，并及时进行干预，对预防肺尘埃沉着病的发生和延缓发展具有重要意义。

Analysis of radiograpy in a coal mine pneumoconiosis survey

Objective To summarize the coal mine pneumoeoniosis patients＇ characteristics and provide the necessary basis for coal worker＇s pneumoconiosis （CWP） prevention,diagnosis and treatment. Methods The information of the quality of chest X-ray and small opacity imaging features including type, profusion and distribution in 486 coalminer in 2013 were analyzed. Results In these cases, good chest X-Ray film rate was 89.7%（436/486）; Among 26 cases of patients confirmed with pneumoconiosis, small opacity was found in 67 lung field and p, q opacity was the most type, accounting for 91.0%（61/67）; small opacity distribution in the middle or lower lung field was accounting for 83.6% （56/67）; small opacity general profusion category 1 was accounting for 88.5% （23/26）in confirmed pneumoeoniosis. Conclusion Good chest X-ray is the basis of CWP diagnosis; the X-ray characteristics of small opacity have a certain regularity;pneumoeoniosis survey can find early CWP patients and high-risk groups, and early intervention can delay the development of pneumoconiosis disease.
