中文摘要：

胸部高分辨率CT已经成为间质性肺疾病重要的诊断手段,支气管肺泡灌洗作为胸部影像的补充,其在间质性肺疾病的诊断中仍然具有一定的价值.除了某些少见的间质性肺疾病,单独应用支气管肺泡灌洗液细胞学分析不足以诊断间质性肺疾病的特异类型,但是结合临床和影像表现,支气管肺泡灌洗液分析可以支持某种特异性的诊断,使患者一定程度上避免外科肺活检.

英文摘要：

High-resolution computed tomography of thorax has become an important diagnostic tool to narrow the differential diagnosis in interstitial lung disease. Bronchoalveolar lavage fluid cell analysis in the diagnosis and management of interstitial lung disease is now debated and controversial. Except for some rare interstitial lung disease, bronchoalveolar lavage cytology analysis is insufficient to diagnose the specific type of interstitial lung disease, Combination of clinical and radiological findings, bronchoalveoalr lavage analysis fluid may provide useful clues for the diagnostic evaluations of patients with suspected interstitial lung disease.
