摘　　要：目的分析矽肺的MSCT影像特征,提高其诊断和鉴别诊断能力。方法回顾性分析39例矽肺患者的MSCT影像资料,对其影像特征进行分析整理,发现其较特征的CT影像表现,为其诊断和鉴别诊断提供依据。结果 39例矽肺患者CT图像上均可见散在小类圆形矽结节及不同程度肺间质纤维化改变。非钙化矽结节平均CT值约为60.5±9.2HU。21例患者可见融合斑,19例患者可见胸膜斑。肺门淋巴结增大28例,伴钙化20例。肺气肿35例,弥漫性肺气肿19例,同时伴有或单纯局灶性肺气肿23例。合并结核11例,其中空洞形成7例。结论多数矽肺患者MSCT具有较特征的影像表现,MSCT对其诊断、鉴别诊断具有重要价值。Objective To improve diagnosis and differential diagnosis of silicosis by analyzing its MSCT im-aging features. Methods The MSCT data of 39 silicosis cases were analyzed retrospectively. By analyzing and sum-marizing these data, specific imaging features could be found to provide basis for silicosis diagnosis and its differential diagnosis. Results Scattered small circular silicon nodules and various degrees of interstitial fibrosis were visible on all 39 silicosis patients′ CT data. The average value of non-calcified silicosis nodule was about 60. 5 ± 9. 2 HU. A-malgamate plaque was visible in 21 cases, and pleural plaque in 19 cases. Enlarged hilar lymph node was visible in 28 cases, among which 20 cases also suffered from calcification. Emphysema was observed in 35 cases, and diffuse emphysema in 19 cases. Either accompanied emphysema or simply localized emphysema was observed in 23 cases. Silicosis complicated with tuberculosis was observed in 11 cases, among which cavity could be seen in 7 cases. Con-clusion Because most patients with silicosis have specific MSCT imaging features, MSCT is significant in silicosis diagnosis and differential diagnosis.
