摘要
目的:探讨尘肺病在CT上病灶的分布特点.方法:收集在我院2018年1月至2022年12月期间行胸部CT检查并经职业病诊断机构诊断为尘肺病的51例患者作为研究对象,观察病灶的位置、大小、密度、累及范围,以病灶的在肺段、肺叶的分布情况作为观察重点.结果:尘肺病病灶有2～10mm的结节及不规则小阴影、大于10mm的大阴影,大阴影存在于尘肺叁期,呈"八"形分布于上肺,2～10mm的小阴影在各肺段、肺叶均可有分布,并且在肺段间移行区、肺叶间移行区有明显的病灶分布,胸膜下肺组织少有病灶分布.结论:尘肺病病灶分布有一定特征性,认识这些特征有肋于提高尘肺病的诊断与鉴别诊断能力.
Abstract
Objective:To explore the distribution characteristics of pneumoconiosis lesions on CT.Method:A total of 51 patients who underwent chest CT examination and were diagnosed with pneumoconiosis by an occupational disease diagnosis institution in our hospital from January 2018 to December 2022 were collected as research subjects.The location,size,density,and extent of the lesion were observed,with a focus on the distribution of the lesion in the lung segments and lobes.The results showed that the focus of pneumoconiosis had 2-10mm nodules and irregular small shadows,as well as large shadows＞10mm.The large shadows existed in the third stage of pneumoconiosis and were distributed in an"eight"shape in the upper lung.The 2-10mm small shadows were distributed in all lung segments and lobes,and there was a clear distribution of lesions in the transition area between lung segments and lobes.There were few lesions in the subpleural lung tissue.Conclusion:The distribution of pneumoconiosis lesions has certain characteristics,and understanding these characteristics is beneficial for improving the diagnosis and differential diagnosis ability of pneumoconiosis.
