摘　　要：目的探讨结缔组织病相关肺间质改变的X线及高分辨率CT特征表现。方法回顾性分析65例结缔组织相关肺间质病变的X线及高分辨率CT表现,分析其相关临床意义。结果 65例患者均行DR及高分辨率CT。DR表现:40例(61.5%)表现为不同程度的肺纹理紊乱、模糊,伴有斑点、斑片状阴影、胸膜增厚等,23例(35.4%)胸片报告无异常,8例(12.3%)报告为其他病变。在HRCT上表现为磨玻璃影35例,网格影32例,结节影12例,蜂窝影9例,实变影5例;HRCT中,同一肺间质病变患者常有两种或两种以上表现并存。结论 X线对肺间质病变诊断的敏感性及特异性均较低。HRCT能早期、无创地诊断肺间质病变,判断是否有可逆改变,明确肺部改变的范围和类型,为临床治疗提供重要参考。Purpose To evaluate the clinical utility of high-resolution computed tomography（HRCT） and digital radiography（DR） in diagnosing interstitial lung disease of connective tissue disease.Materials and Methods DR and HRCT manifestations of 65 patients with interstitial lung disease of connective tissue disease were analyzed retrospectively.Results All patients were examined with DR and HRCT.DR findings included： 40 cases with disorder of lung markings,23 with nomal chest radiography,and 8 with order diseases.HRCT showed ground-glass opacification in 35 cases,reticulation in 32 cases,nodules in 12 cases,honeycombing in 9 cases and consolidation in 5 cases.There always more than two kind of features in HRCT.Conclusion X ray diagnosis of interstitial lung disease were lower sensitivity and specificity.HRCT can be an early,noninvasive diagnosis of interstitial lung disease,Determine whether changes were reversible,providing an important reference for clinical treatment.
