本文对以往确诊的29例碳素尘肺进行分析,发现其X线表现与矽肺存在着很大差距。矽肺以孤立的节结为主,而碳素尘肺则以肺纹理和网织阴影改变为主,特别是碳素尘肺出现的肋骨伴随影在矽肺和其它尘肺片中从未见过。因此单纯追求节结必然会延误碳素尘肺的诊断和治疗。本文还对肋骨伴随影的形成作了初步探讨。 In this paper, the past diagnosis of 29 cases of carbon pneumoconiosis were analyzed and found that the X-ray performance and silicosis there is a big gap. Silicosis is dominated by isolated nodules, whereas carbon pneumoconiosis is predominantly altered by lung texture and reticulation shadowing. In particular, rib appearing with carbon pneumoconiosis has never been seen in silicosis and other pneumoconiosis tablets. Therefore, the simple pursuit of node knot is bound to delay the diagnosis and treatment of carbon pneumoconiosis. This article also made a preliminary discussion about the formation of rib accompanied shadow.
