摘　　要：目的探讨电焊工尘肺高分辨CT(HRCT)影像表现及预后改变.方法回顾性分析11例经职业病诊断的电焊工尘肺患者HRCT影像表现及随访改变.结果7例(63.7%)患者出现小叶中心结节影,5例(45.5%)患者出现小叶中心斑片状磨玻璃影("淡墨征"),5例(45.5%)患者出现分支状细线影,2例(18.2%)患者出现小叶间隔增厚,3例(37.5%)患者影像表现较前好转.结论电焊工尘肺HRCT影像表现主要为两肺弥漫分布小叶中心结节影、"淡墨征"及分支状细线影,肺门、纵隔淋巴结肿大、钙化罕见.当影像表现以叶中心小结节影或"淡墨征"时,更有可能在脱离暴露后好转.Objective To explore the high-resolution computed tomography(HRCT)imaging findings and prognosis for the welder pneumoconiosis.Methods The HRCT imaging findings and follow-up changes in 11 cases of welder pneumoconiosis diag-nosed by occupational diseases were analyzed retrospectively.Results There were 7 cases(63.7%)showed central lobular nodule shadow,5 cases(45.5%)developed patchy ground glass shadows in the center of the lobule("light ink sign"),5 cases(45.5%)showed branching fine line shadow,2 cases(18.2%)showed interlobular septal thickening,and 3 cases(37.5%)showed better ima-ging performance than before.Conclusion HRCT imaging findings of welder pneumoconiosis mainly include diffuse distribution of nodules in the center of lobules,"light ink sign",and branching fine line shadows in both lungs,with rare hilar and mediastinal lymphadenopathy and calcification.When the image shows nodule shadow or"light ink sign"in the center of the lobule,it is more likely to improve after leaving environment exposure.
