100 patients with 122 round pulmonary lesions were examined preoperatively by CT, using either 8 mm or 2 mm sections. The most important findings were: radial extensions were seen on the fine sections in 95% of primary bronchial carcinomas (48 cases), in 60% of lung metastases (31 cases) and in 70% of chronic inflammatory lesions (24 cases), but they were not seen in benign tumours or hamartomas. Similar findings were observed for perifocal consolidation. Calcification was found in 80% of the tuberculomas (15 cases) and in 37% of the hamartomas (8 cases), but it also occurred in 15% of the primary bronchial carcinomas and in almost 13% of the lung metastases. Thin section CT provided more information than did 8 mm sections in 44% patients, concerning the outline of the lesion, and in 60% it was better at showing calcification. It was not possible to define a pattern of calcification which would distinguish benign from malignant lesions.
100例患有122个圆形肺部病变的患者在术前接受了CT检查，扫描层厚分别为8毫米或2毫米。最重要的发现如下：在薄层扫描中，95%的原发性支气管癌（48例）、60%的肺转移瘤（31例）和70%的慢性炎症性病变（24例）可见放射状延伸，但在良性肿瘤或错构瘤中未见。在病灶周围实变方面也观察到类似结果。80%的结核瘤（15例）和37%的错构瘤（8例）发现有钙化，但15%的原发性支气管癌和近13%的肺转移瘤中也有钙化。在44%的患者中，薄层CT在显示病变轮廓方面比8毫米层厚扫描提供了更多信息，在60%的患者中，薄层CT在显示钙化方面表现更佳。无法确定一种能区分良性和恶性病变的钙化模式。
