目的 研究早期蔺草尘肺的HRCT表现。 方法 对经高kVp胸片筛选后的 4 7例蔺草作业工人作胸部HRCT扫描并分析CT表现 ,其中包括 2 5例已被确诊尘肺和 2 2例未能确诊尘肺者。 结果 4 4例显示弥漫性分布的类圆形”P”小结节阴影 ,包括高kVp胸片尚难以确诊蔺草尘肺的 2 2例。 3例上肺野出现大阴影及间质性纤维化。 结论 早期的蔺草尘肺结节在肺小叶内呈随机分布 ,并非仅在小叶中心 ;细支气管壁和小叶间隔未见增厚。HRCT对显示弥漫性尘肺结节灶及肺间质性改变明显优于胸片
Objective To study the HRCT findings of early rushes pneumoconiosis. Methods 47 cases of Rush workers screened by high kVp chest radiography were performed chest CT scan and CT findings were analyzed. Among them, 25 cases of pneumoconiosis and 22 cases of pneumoconiosis were excluded. Results A total of 44 small round nodules (nodules) with diffuse distribution were found, including 22 cases of pneumoconiosis with high kVp. Three cases of lung field showed a large shadow and interstitial fibrosis. Conclusion Early rush pneumoconiosis nodules were randomly distributed in the lobule, not only in the center of the leaflets; there was no thickening of the bronchioles wall and the interlobular septa. HRCT showed diffuse pneumoconiosis and lung interstitial changes significantly better than the chest
