Fifty eight patients with peripheral tumor-like formations of the lung (33 with cancer and 25 with benign formations) were examined by longitudinal tomography and CT. The potentialities of the two techniques in detecting the major semeiotic signs of cancer and malignant formations were compared. The main or major signs, such as the shape of shadow and the pattern of outlines, which make it possible to differentiate benign and malignant formations, are virtually equally imaged by the two techniques. CT is superior to X-ray longitudinal tomography in revealing minor calcifications and microdestructions, hyperplastic intrathoracic lymph nodes. The significance of some symptoms for differential diagnosis calls for further clarification.
对58例肺部周围肿瘤样病变患者（33例癌症患者和25例良性病变患者）进行了纵向断层扫描和CT检查。比较了这两种技术在检测癌症和恶性病变主要体征方面的潜力。两种技术对诸如阴影形状和轮廓模式等有助于鉴别良性和恶性病变的主要或重要体征的成像效果几乎相同。在显示微小钙化、微破坏以及增生性胸内淋巴结方面，CT优于X线纵向断层扫描。某些症状在鉴别诊断中的意义尚需进一步阐明。
