摘　　要：目的 :研究HRCT靶重建技术在尘肺诊断中的应用价值及其影像学表现。方法 :对 5 7例各期煤工尘肺作肺部常规CT扫描 ,然后在主动脉弓顶、隆突水平、气管分叉下 3cm、右膈上 2cm及兴趣区加作HRCT ,并利用所贮存扫描之原始数据进行靶重建。结果 :HRCT靶重建放大成像清晰地显示了尘肺的微细病变 :(1)结节影 10 0 % ;(2 )小叶间隔增厚 98.2 4% ;(3)小叶结构异常98.2 4% ;(4)胸膜下结节 84.2 1% ;(5 )小叶中心型肺气肿 6 3 .15 % ;(6 )胸膜下弧线影 6 4.91% ;(7)小支气管扩张 6 3 .15 % ;(8)磨玻璃样阴影 35 .0 8% ;(9)蜂窝状阴影 15 .78%。并良好的显示了早期病变细节。结论 :HRCT靶重建技术提高了细节显示 ,是显示尘肺微细病变有效而可靠的方法 ,可提供更多的诊断信息。Objective:To study the practical value and imaging expression of target reconstruction technique of HRCT in the diagnosis of pneumoconiosis.Methods:Fifty-seven cases with different level type of pneumoconiosis were first examined by routine CT scan,followed by HRCT examination at top of aortic arch,carina of trachea,3 cm below bifurcation of bronchi,and 2 cm above thd right diaphragm.Target reconstruction have been finished using the raw data stored.Results:Target reconstruction photoimages were cleared to display the morphology of delicate lesions of pneumoconiosis:(1)Nodular shape(100%).(2)Interlobular septal thickening(98.24%).(3)Lobular structure abnormality(98.24%).(4)Subpleural nodes (84.21%).(5)Centrilobular emphysema(63.15%).(6)Subpleural line(64.91%).(7)Bronchiectasis(63.15%).(8)Ground-glass opacity(35.08%).(9)Honeycombing(15.78%),and to display earlier period change details.Conclusion:HRCT target reconstruction technique may make lesion dispaly more detail than comventional and high-resblution CT.It is reliable to display the delicate lesions of pneumoconiosis and provide more diagnostic information.
