高分辨率计算机断层扫描（CT）的12个孤立的，膨胀，新鲜的肺在尸检获得薄，纸裱肺切片在相同的水平进行了比较。在6个被认为本质正常的肺中，高分辨率CT显示小叶间隔和小叶核心中的肺动脉正常，但小叶细支气管不可见。水肿液导致小叶间隔增厚和可见性增加。在三个肺气肿的肺，高分辨率CT准确地显示了肺气肿的程度，并建议其小叶中心的性质。在两个肺蜂窝，囊肿内衬纤维化很容易看到高分辨率CT扫描。在不太严重的受累区域，高分辨率CT扫描可见间隔增厚和小叶内纤维化，但看不到小的（1 mm）囊肿。高分辨率CT能显示正常肺小叶的某些特征和各种疾病引起的结构改变。
High-resolution computed tomography (CT) scans of 12 isolated, inflated, fresh lungs obtained at autopsy were compared with thin, papermounted lung sections obtained at the same levels. In six lungs considered intrinsically normal, high-resolution CT showed normal interlobular septa and pulmonary arteries in the lobular core, but lobular bronchioles were not visible. Edematous fluid resulted in thickening and increased visibility of interlobular septa. In three emphysematous lungs, high-resolution CT accurately demonstrated the degree of emphysema and suggested its centrilobular nature. In two lungs with honeycombing, cysts lined by fibrosis were easily seen on high-resolution CT scans. In less severely involved areas, septal thickening and intralobular fibrosis were seen on high-resolution CT scans, but small (1 mm) cysts were invisible. High-resolution CT was able to demonstrate some features of the normal secondary pulmonary lobule and structural alterations produced by various diseases.
