总结Ⅰ期电焊工尘肺的高分辨率CT(HRCT)表现,探讨其诊断价值。方法对14例Ⅰ期电焊工尘肺行胸部HRCT扫描,归纳征象。结果主要征象为弥漫分布、直径1~4mm的小结节影;程度不同的细网状影;密度淡、边缘模糊、直径0.5~1cm的小片团样影;肺野磨玻璃样变;支气管和肺血管改变。结论HRCT能很好地显示电焊工尘肺的肺部改变,具有重要诊断价值
To summarize the high resolution CT (HRCT) performance of stage Ⅰ welder pneumoconiosis and to discuss its diagnostic value. Methods Thoracic HRCT was performed in 14 cases of stage Ⅰ electrician pneumoconiosis. The signs were summarized. Results The main signs were diffuse distribution, small nodules with diameter of 1 ~ 4mm, fine reticular densities with different degrees, small densities of density, blurred edges, small pellets with diameter of 0.5 ~ 1cm, Bronchial and pulmonary vascular changes. Conclusion HRCT can well show the change of lung in welder pneumoconiosis, which has important diagnostic value
