High-resolution CT findings of 47 small pulmonary adenocarcinomas (20 mm or less in diameter) were correlated with the pathological classification of Noguchi et al. All seven tumors of Noguchi's type A showed homogeneous groundglass attenuation and no air densities except air bronchogram. Linear density radiating into surrounding lung parenchyma was not found in type A tumors. On the other hand, 38 of 40 tumors of types B, C, and D had some dense opacity domain, which increased in size in that order. Coarse indentation, which was not found in cases of type A and B tumors, was considered to be an important finding in differentiating cases in the good prognosis group (types A and B) from those in the poor prognosis group (types C and D).
47例直径20mm及以下的小肺腺癌的高分辨率CT表现与Noguchi等人的病理分类相关。Noguchi A型的所有7个肿瘤均表现为均匀的磨玻璃样衰减，除了空气支气管造影外无空气密度。A型肿瘤中未发现向周围肺实质放射的线状密度影。另一方面，B、C和D型的40个肿瘤中有38个有一些致密的不透明区域，其大小按此顺序增加。粗压迹在A型和B型肿瘤中未发现，被认为是区分预后良好组（A型和B型）与预后不良组（C型和D型）病例的重要表现。
