硬皮病浸润肺的CT表现

CT Manifestation of Lung Infiltrated by Scleroderma

目的：从ＣＴ及ＨＲＣＴ图像上，在次级肺小叶水平观察硬皮病浸润的进展及估订预后。材料和方法：７例硬皮病患者均有典型临床表现及相应的实验室检查，均行ＣＴ及ＨＲＣＴ扫描。ＨＲＣＴ层厚１－２ｍｍ，用高分辨图像重建法进行图像重建。结果：磨玻璃样改变为肺部受浸润的进展期，小叶间隔增厚、蜂房样改变及肺内带状影为后期改变。结论：应用ＣＴ及ＨＲＣＴ检查，可以帮助确定硬皮病浸润肺的程度、分期并能估计预后。

Purpose: In CT, especially, HRCT images, the authors evaluated the infiltration of Scleroderma in lungs from the level of secondacy pulmonary lobule and estimated the prognosis. Materials and Methods: 7 scleroderma patients with typical clinical symptoms and corresponding laboratory tests undeewent CT and HRCT examinations. HRCT images were reconstructed with high spatial resolution used 1-2mm collimation. Results: In developing stage, ground-glass change was shown. In end stage, the thickening lobular septa, honeycomb and band-like changes were found. Conclusion: CT and HRCT can help to determine the stages, the infiltrating degree, and to estimate the prognosis in patients with scleroderma.
