特发性肺间质纤维化的CT表现

目的：探讨特发性肺间质纤维化的CT表现。方法选取96例特发性肺间质纤维化患者作为研究对象，对所选患者均采用胸部常规CT扫描，病变区采用薄层CT扫描，进而探讨特发性肺间质纤维化的CT表现。结果96例患者的病灶部位均呈弥漫性分布，其中双肺密度大多不均，以双肺下野外周部为主，多发于肺下叶基底部，其中65例为双侧，31例为单侧；特发性肺间质纤维化的主要CT征象为：小叶间隔不规则增厚60例，网状改变50例，磨玻璃样改变及密度影32例，小叶性肺气肿68例，其中46例为小叶中心型肺气肿，22例为全小叶型肺气肿，蜂窝状、囊状45例，胸膜下线38例，两肺下叶牵拉性支气管扩张30例，结节影18例。结论 CT能在一定程度上反映特发性肺间质纤维化病变情况，在特发性肺纤维化的诊断中具有很高的应用价值，值得临床上进一步推广。

CT features of idiopathic pulmonary fibrosis

Objective To investigate the CT features of idiopathic pulmonary fibrosis. Methods Ninety-six patients with idiopathic pulmonary fibrosis were chosen as research subjects. The selected patients all underwent chest high-resolution CT scan of the chest to explore CT features of idiopathic pulmonary fibrosis. Results The selected 96 patients with idiopathic pulmonary fibrosis showed a diffuse distribution lesion site, where most of the uneven lung density to lower lung field periphery, more hair at the base of the lower lobe of the lung, of which 65 cases were bilateral, 31 cases were unilateral. The main CT features of idiopathic pulmonary fibrosis were 60 cases of irregular septal thickening, 50 cases of reticular change, 32 cases of ground-glass changes and density, 68 cases of lobular emphysema （including 46 cases of centrilobular emphysema and 22 cases of the whole lobular emphysema）, 45 cases of honeycomb and cystic, 38 cases of pleural off the assembly line, 30 cases of bronchiectasis pulling the lower lobes of both lungs, 18 cases of nodules. Conclusion To some degree the CT features of inidiopathic pulmonary fibrosis are characteristic. CT has a high application in diagnosis of idiopathic pulmonary fibrosis, which can be worthy of clinical further promotion.
