摘　　要：目的:探讨周围型肺癌早期的CT表现特点。材料与方法:收集经病理证实的31例周围型肺癌患者的影像资料,分析其胸部正侧位片及CT片的影像学特征。结果:X线胸片上26例病灶密度较高、轮廓模糊,结节状或球形,5例呈肺炎样小片状稍高密度,CT图像上有23例显示分叶征;18例显示细短毛刺和锯齿征;26例有血管集束征;22例显示空泡征/细支气管充气征;20例显示胸膜凹陷征。CT动态增强扫描6例中有4例CT增强值在20 Hu～60 Hu之间,<20 Hu 1例,>60 Hu 1例。结论:X线胸片及CT对周围型肺癌的诊断及鉴别诊断具有重要的价值。Purpose： To investigate the CT features of early peripheral lung cancer. Materials and Methods： Re- view the image material of the 31 lung cancer patients confirmed by pathology. Analysis its anteroposterior films and CT image findings. Results ： 26 cases of them showed hyper density, vague outline and nodular or spherical shape. 5 cases dispayed as pneumonia like slightly high density on films. Most of the lesion have the appearence of Vascular convergence sign, lobula- tion, fine short burr, vacuole sign, air-bronchogram, pleura1 indentation on CT images. Four of the six cases CT enhanced value were 20 - 60 HU, 〈 20 Hu in 1 case and 〉 60 Hu in 1 case. Conclusion： X-ray film and CT image have vary im- portant value for the diagnosis and differential diagnosis of peripheral lung cancer.
