1、肺尘埃沉着病与肺结核的X线胸片影像分析【摘要】目的探讨肺尘埃沉着病和肺结核x线影像学特征。方法拍摄高仟伏胸片的肺尘埃沉着病136例及肺结核48例(其中血行播散型肺结核22例，继发性肺结核伴空洞26例),对二者的X线图像进行分析。结果136例肺尘埃沉着病高仟伏胸片上小结节大小均匀为54例(39.71%),密度均匀为15例(11.03%),分布均匀27例(19.85%),22例血行播散型肺结核小结节大小均匀的有16例(72.73%),密度均匀的有15例(68.18%),分布均匀15例(68.18%),二者在大小、密度、分布方面差异有统计
2、学意义(P<0.05)o单纯肺尘埃沉着病空洞以厚壁空洞为主，结核空洞以薄壁空洞最常见，周围常伴有卫星灶，肺尘埃沉着病结核空洞直径相对较大。结论肺尘埃沉着病与肺结核高仟伏胸片表现有差异，分析二者差异有助于提高诊断准确性。【关键词】肺尘埃沉着病；肺结核；高仟伏胸片ImaginganalysisofX~raychestradiographofpneumoconiosisandtuberculosisWANGYing-jie・StateProductionSafetySupervisionAdministrationofOccupation
