The ILO classification of small and large opacities is the basis for the compensation of patients with pneumoconiosis. In order to validate the radiological findings, we compared the ILO classification with the gradings of pneumoconiosis in the post mortem investigation (n = 126). An ILO classification of 1/0 used as the threshold value for accepting the diagnosis of a pneumoconiosis was 100% sensitive with a specificity of 2%. With a value of 2/3 the sensitivity decreased to 60% and specificity increased to 74%. The grading of large opacities in the radiograph correlated well with the post mortem findings (rs = 0.71; p < 0.001). For accepting the diagnosis pneumoconiosis from the radiograph alone a threshold value of 1/0 is not specific. The ROC-plot revealed that specificity reached acceptable levels with an ILO classification of at least 2/3.
国际劳工组织（ILO）对小阴影和大阴影的分类是尘肺病患者赔偿的依据。为了验证放射学检查结果，我们将ILO分类与尸检调查（n = 126）中的尘肺病分级进行了比较。将ILO分类为1/0用作接受尘肺病诊断的阈值时，敏感性为100%，特异性为2%。当值为2/3时，敏感性降至60%，特异性升至74%。X线片中大阴影的分级与尸检结果相关性良好（rs = 0.71；p < 0.001）。仅根据X线片接受尘肺病诊断时，1/0的阈值并不具有特异性。ROC曲线显示，ILO分类至少为2/3时，特异性达到可接受水平。
