目的探讨胸膜下透亮带在CT诊断尘肺肺部弥漫性粟粒样病变中的价值。方法回顾性分析138例以肺部弥漫性粟粒样病变为主要征象的尘肺病和其他肺部疾病患者CT资料。结果胸膜下透亮带在尘肺弥漫性粟粒样病变中的出现率为87.6%(78/89),在其他弥漫性粟粒样病变中的出现率为18.4%(9/49)。结论肺部弥漫性粟粒样病变胸膜下透亮带对鉴别尘肺病有重要的指导意义。
Objective To investigate the value of subpleural translucent band in the diagnosis of diffuse miliary lesions in lungs of pneumoconiosis. Methods We retrospectively analyzed CT data of 138 patients with pneumoconiosis and other pulmonary diseases, the main signs of which were pulmonary diffuse miliary lesions. Results The frequency of subpleural translucent bands in diffuse miliary lesions of pneumoconiosis was 87.6% (78/89) and in other diffuse miliary lesions was 18.4% (9/49). Conclusion Pulmonary diffuse miliary lesions in the subpleural translucent zone is important for differential diagnosis of pneumoconiosis.
