本文报告应用1986年《尘肺X线诊断标准》对按1963年《矽肺和石棉肺X线诊断标准》诊断的642例8种尘肺、(矽肺、煤矽肺、石棉肺、水泥尘肺、云母尘肺、电焊工尘肺、铸工尘肺及磨工尘肺)和120例观察对象的X线胸片进行了X线诊断及分期对照。同时对这8种尘肺应用1986年《尘肺X线诊断标准》做了胸片X线形态分析。 两个X线诊断标准的总符合率为92.3％;观察对象升为Ⅰ期的升期率为4.2％;Ⅰ期降期率为0.7％;Ⅱ期降期率为31.4％。8种尘肺X线胸片形态学改变以混合形小阴影为主,不规则形小阴影在尘肺X线诊断中与类圆形小阴影有相同的作用。
This paper reports the application of 1986 pneumoconiosis diagnostic criteria to 642 cases of 8 pneumoconiosis diagnoses (silicosis, coal silicosis, asbestosis, cement pneumoconiosis, mica pneumoconiosis, electric welding Workers pneumoconiosis, casting workers ’pneumoconiosis and mill workers’ pneumoconiosis) and X-ray diagnosis and staging of 120 cases of observation object. At the same time on these eight kinds of pneumoconiosis application of 1986 “pneumoconiosis diagnostic criteria” made a chest X-ray morphological analysis. The coincidence rate of the two X-ray diagnostic criteria was 92.3%. The ascending rate of the observation object to stage I was 4.2%. The stage Ⅰ down rate was 0.7%. The stage Ⅱ down-time rate was 31.4%. Eight kinds of pneumoconiosis X - ray changes in morphology to mixed small shadows, irregular small shadows in the pneumoconiosis X - ray diagnosis with the same circular small shadow have the same effect.
