Results Compared high kV X-ray chest film with spiral CT,to simplex silicosis,X-ray films coincided with CT scans;to mixed silicosis,the effect of CT scans were better than X-ray's;to large nodule,coalesced progressive massive fibrosis,the detected ratio of CT scans were higher than X-ray chest films;to silicosis complication,for example,emphysema,pleural thickening,phthisic,mediastinal impairment lympy node etc,CT scans were more reliable than X-ray films,especially HRCT can earlier find silicotic nodule and fine structure of focus.Selective application of CT scan,had great diagnostic value in complicated silicosis and silco-tuberculosis and lung cancer complicated with silicosis etc.

结果 高千伏X线胸片与螺旋CT作对比，结果对单纯矽肺并发肺癌，CT片与X线胸片基本一致；对于复杂矽肺并发肺癌CT优于X线胸片；对于大结节、肺内进行性大块纤维化(progressive massive fibrosis，PMF)融合、空洞及钙化CT检出率明显高出胸片；对矽肺并发肺癌的合并其他如肺气肿、胸膜肥厚、结核、纵隔淋巴受累等CT均较胸片可靠；特别是HRCT能早期发现矽肺肿块样病灶中细微结构，选择性应用CT，对复杂矽肺并发肺癌合并结核等鉴别诊断有很大价值。
