特发性肺间质纤维化的HRCT诊断（附54例分析）

目的探讨高分辨率CT（HRCT）对特发性肺纤维化（IPF）的诊断及鉴别诊断的价值。方法经临床及病理证实的54例IPF患者经HRCT扫描后对兴趣区行高分辨率薄层回顾性重建,观察病变的分布及HRCT表现。结果IPF的主要HRCT表现：1）磨玻璃样密度影;2）网状改变;3）蜂窝肺;4）胸膜下间质纤维化;5）肺气肿;6）牵拉支气管扩张。结论HRCT能细致、准确地反映IPF的影像特征,但各种征象均可见于其他各种肺部间质性疾病,HRCT在能够排除其它肺纤维化病变并有以上明确CT表现时可诊断为IPF。

HRCT Diagnosis of Idiopathic Pulmonary Fibrosis:AnAnalysis of 54 Cases

Objective To study high-resolution CT （HRCT） diagnosis and differential diagnosis of idiopathic pulmonary fibrosis （IPF）. Methods The clinical and pathological confirmed 54 cases of IPF patients by HRCT scan line after the interested area high-resolution thin-layer retrospective reconstruction, Observe the distribution and HRCT signs of disease. Results The IPF main HRCT performance： 1） ground-glass opacity; 2） mesh change; 3） cell lung; 4） subpleural interstitial fibrosis; 5）, pulmonary emphysema; 6） traction bronchiectasis. Conclusion HRCT can be carefully and accurately reflect the image features of IPF, But a variety of signs can be seen in a variety of other interstitial diseases, HRCT in to the exclusion of other pulmonary fibrosis and is more clear when the performance of CT diagnosis of IPF.
