We developed the standard digital images (SDIs) to be used in the classification and recognition of pneumoconiosis. From July 3, 2006 through August 31, 2007, 531 retired male workers exposed to inorganic dust were examined by digital (DR) and analog radiography (AR) on the same day, after being approved by our institutional review board and obtaining informed consent from all participants. All images were twice classified according to the International Labour Office (ILO) 2000 guidelines with reference to ILO standard analog radiographs (SARs) by four chest radiologists. After consensus reading on 349 digital images matched with the first selected analog images, 120 digital images were selected as the SDIs that considered the distribution of pneumoconiosis findings. Images with profusion category 0/1, 1, 2, and 3 were 12, 50, 40, and 15, respectively, and a large opacity were in 43 images (A = 20, B = 22, C = 1). Among pleural abnormality, costophrenic angle obliteration, pleural plaque and thickening were in 11 (9.2%), 31 (25.8%), and 9 (7.5%) images, respectively. Twenty-one of 29 symbols were present except cp, ef, ho, id, me, pa, ra, and rp. A set of 120 SDIs had more various pneumoconiosis findings than ILO SARs that were developed from adequate methods. It can be used as digital reference images for the recognition and classification of pneumoconiosis.
我们开发了标准数字图像 (SDI)，用于尘肺的分类和识别。2006 年 7 月 3 日至 2007 年 8 月 31 日，在获得机构审查委员会批准并获得所有参与者的知情同意后，我们对 531 名暴露于无机粉尘的退休男性工人进行了数字 (DR) 和模拟 (AR) 放射摄影同日检查。所有图像均由 4 名胸部放射科医生根据国际劳工组织 (ILO) 2000 年指南以及 ILO 标准模拟射线照片 (SAR) 进行了两次分类。在对与第一组模拟图像匹配的 349 张数字图像进行了共识阅读后，选择了 120 张数字图像作为 SDI，这些图像考虑了尘肺发现的分布。弥漫度类别 0/1、1、2 和 3 的图像分别为 12、50、40 和 15，并有 15 个大阴影。在胸膜异常中，肋膈角闭塞、胸膜斑和胸膜增厚分别在 11（9.2%）、31（25.8%）和 9（7.5%）张图像中出现。29 个符号中除了 cp、ef、ho、id、me、pa、ra 和 rp 外，其他符号都存在。除了 ILO SAR 外，SDI 还具有更多不同的尘肺发现，这是通过适当的方法开发的。它可作为尘肺识别和分类的数字参考图像。
