为了验证《1986尘肺诊断标准》的读片重复性,作者用集体读片方式分析读片差异、分析原因。 两次该片诊断符合程度75％;小阴影形态70％;密集度75％;分布范围65％;大阴影、胸膜斑、小阴影聚集及弥漫胸膜增厚则完全相符。 影响诊断结果相符程度的主要因素是密集度判定差异。产生差异的原因可能与标准片对比方法、胸片示局部小阴影密集度较高及混合形态阴影对判定的影响等因素有关。 In order to verify the repeatability of the “1986 Pneumoconiosis Diagnostic Standard”, the author analyzed the differences between the readings by means of collective reading and analyzed the reasons. The diagnostic accuracy of the film was 75%; the shape of the small shadow was 70%; the density was 75%; the distribution range was 65%. The large shadow, the pleural patch, the small shadow and the diffuse pleural thickening were completely consistent. The main factor that affects the consistency of diagnostic results is the difference in concentration determination. The reasons for the differences may be related to the standard film comparison method, chest X-ray showed a small local high concentration of shadow and the shadow of mixed morphology to determine the impact of other factors.
