| 目的 探讨尘肺的HRCT表现及其临床应用价值。方法 对32例尘肺病人行HRCT扫描,并对其HRCT表现进行分析。结果 32例尘肺病人中,28例(87.5%)表现为淋巴管周围分布结节,结节直径2~5 mm者24例(75%);29例(90.6%)显示散在、局灶小叶间隔增厚;23例(71.9%)可见间隔旁或瘢痕旁肺气肿改变;28例(87.5%)出现淋巴结增大,8例(25%)出现蛋壳状钙化;15例(46.9%)出现融合片影、块影,12例(37.5%)出现空洞,两者均以两肺上野偏后分布为主。结论 HRCT可以显示尘肺的细微病变,在尘肺的诊断和鉴别诊断中具有重要价值。 |

| Objective To study the HRCT features of pneumoconiosis and its value in clinical application.Methods Thirty-two cases of pneumoconiosis were examined with HRCT and then the HRCT features were analysed.Results Of all 32 pneumoconiosis,perilymphatic nodules were seen in 28(87.5%),24 (75%) showed nodules of 2-5 mm in diameter,29(90.6%) showed scattered and local interlobular septal thinkening,paraseptal and paracicatricial emphysema were seen in 23(71.9%),28(87.5%) showed enlarged hilar and mediastinal lymph nodes,but egg shell calcification was only seen 8(25%),15(46.9%) showed coalescence of small nodules to larger nodules and masses,12(37.5%) showed cavitation,both with a predominance for the upper lung zones,especially posteriorly.Conclusion HRCT can show the delicate texture of pneumoconiosis and plays an important role in the diagnosis and differential diagnosis of pneumoconiosis. |
