High-resolution computed tomographic (HRCT) scans and chest radiographs were obtained in 23 patients with progressive systemic sclerosis (PSS) to assess the diagnostic merits of HRCT compared with chest radiography in detecting interstitial lung involvement in these patients. HRCT scans showed interstitial disease in 21 patients (91%). The most frequent finding was the so-called subpleural lines, which were demonstrated in 17 patients (74%). Honeycombing was seen in seven patients (30%), while parenchymal bands were seen in six patients (26%). Chest radiographs, on the other hand, showed definite interstitial opacification patterns in only nine patients (39%); six patients (26%) had equivocal reticular areas of attenuation, while eight patients (35%) had normal chest radiographs. Thus, HRCT is much more sensitive than chest radiography when assessing minimal interstitial lung involvement in patients with PSS.
对23例进行性系统性硬化症（PSS）患者进行了高分辨率计算机断层扫描（HRCT）和胸部X光检查，以评估HRCT与胸部X光相比在检测这些患者间质性肺受累方面的诊断价值。HRCT扫描显示21例患者（91%）存在间质性疾病。最常见的表现是所谓的胸膜下线，17例患者（74%）出现此表现。7例患者（30%）可见蜂窝状改变，6例患者（26%）可见实质带。另一方面，胸部X光检查仅9例患者（39%）显示明确的间质性混浊模式；6例患者（26%）有可疑的网状衰减区域，8例患者（35%）胸部X光检查正常。因此，在评估PSS患者的轻微间质性肺受累时，HRCT比胸部X光检查敏感得多。
