炭黑引起作业工人所患的尘肺叫炭黑尘肺。它的诊断沿用统一的尘肺X线诊断标准,主要以X线胸片上显示的各种纤维化小阴影为依据。由于炭黑所致的肺纤维化很轻微,一般X线胸片肉眼读片误差较大,特别是干扰细微变化较大的肺气肿存在时,会给诊断带来困难。肺密度能较准确地反映肺内纤维化及空气容积状况。国外现已使用CT Carbon black causes workers to suffer from pneumoconiosis called carbon black pneumoconiosis. Its diagnosis follows the same diagnostic standard of pneumoconiosis, which is mainly based on a variety of small fibrosis images displayed on X-ray. Pulmonary fibrosis due to carbon black is very slight, the general X-ray large errors in the human eye, especially interfering with minor changes in the presence of emphysema, it will bring the diagnosis difficult. Lung density can more accurately reflect the status of pulmonary fibrosis and air volume. Foreign now use CT
