摘　　要：弥漫性间质病变是以肺间质的炎症和纤维化为特征的异质性疾病组成的疾病系列,该病群种类繁多,目前共有200余种,分类方法多种多样。这些疾病的临床表现、影像学改变、肺功能损害非常相似,但是它们的病因、发病机制、病理特征、治疗和预后有所不同,所以对一些少见的弥漫性间质病变如:特发性肺含铁血黄素沉着症、弥漫性肺淀粉样沉着症、慢性嗜酸性粒细胞肺炎、显微镜下多血管炎等的研究非常重要,有助于及时诊断,早期治疗,明显改变预后。由于CT具有分辨率高、无前后结构重叠等优点,对小病灶及早期病变的发现多十分敏感,尤其高分辨率CT能提供更为丰富的病变细节及影像学资料,是研究肺部弥漫性间质病变理想的工具,既可以用来诊断间质病变,又可以随访观察疾病演变,判断疗效。Diffuse interstitial lesions are a series of diseases consisting of heterogeneous diseases characterized by inflammation and fibrosis of the pulmonary interstitial. The disease features as a wide range of disease groups, reaching a total of more than 200 kinds, with various methods of classification. It is very similar referring to the clinical manifestations, imaging changes, lung function damage causing by these diseases, while the etiology, pathogenesis, pathological features, treatment and prognosis are different, so it is rather valuable to research on some of the rare diffuse interstitial diseases, such as idiopathic lung hemosiderosis, diffuse pulmonary amyloidosis, chronic eosinophilic pneumonia, microscopic polyangitis.Therefore, the patients will gain timely diagnosis and early treatment, which will significantly change the prognosis. Because CT has the advantages of high resolution, no overlapping before and after the structure,and it＇s highly sensitive to small lesions and early lesions,even high resolution CT can provide more details of the lesion and imaging data, so it is the ideal equipment to study diffuse interstitial lung disease. It can be used not only in diagnosing interstitial lesions, but also observing the disease evolutions and determining the efficacy.
