[摘要] 目的 对比分析周围型肺癌通过X线及CT检查表现出来的不同征象的特点，进一步确定X线及CT检查对诊断周围型肺癌的临床价值。 方法 将我院2008年12月～2010年12月收治的68例周围型肺癌患者的影像学检查资料包括X线片、CT扫描资料进行总结分析。 结果 CT检查确诊的癌灶比率明显高于X线检查，两组肿块征、毛刺征、棘样突起、空洞、胸膜凹陷征、空泡征及支气管征、血管集束征、肺门与纵隔淋巴结肿大、骨转移、胸水等各种征象分别比较，差异有统计学意义或高度统计学意义(P < 0.05或P < 0.01)，除外分叶征。 结论 CT诊断周围型肺癌的准确性明显优于X线检查，将二者结合起来应用于周围型肺癌的检查具有重要的临床意义，值得推广和应用。

[Abstract]Objective To compare and analyze the peripheral lung cancer through the application of X-ray and CT, and further to demonstrate the characteristics of the different signs of X-ray and CT in the diagnosis peripheral lung cancer clinical value. Methods From December 2008 to December 2010, 68 cases peripheral lung cancer patients were treated, and the imaging data including X-ray, CT scan data were analyzed. Results CT examination confirmed the foci ratio was significantly higher than the X-ray examination, tumor characteristics, burr sign, spine-like protrusions, voids, pleural indentation, vacuole sign and bronchial symptoms, vascular cluster symptoms, hilar and mediastinal lymph nodes, bone metastases, pleural effusion, and other signs, respectively of two groups, the difference was statistically significant (P < 0.05 or P < 0.01), except lobulation. Conclusion CT diagnosis peripheral lung cancer is significantly better than X-ray examination, and combine the two kinds methods in the examination of peripheral lung cancer has important clinical significance, worthy of promotion and application.

周围型肺癌是发生在段和段以下支气管或肺小叶的肿瘤，近年来发病率逐渐上升。由于病情发展较迅速，且易发生转移，多数患者诊断时已是晚期，失去了手术机会，故早期发现是提高诊断及治疗效果的关键[1]。在周围型肺癌的诊断中，常用的影像学方法有X线片、体层、血管造影、CT、MRI等，其中X线、CT检查对于周围型肺癌患者的诊断和治疗具有重要作用[2]。本研究旨在对比分析周围型肺癌通过应用X线及CT检查表现出来的不同征象的特点，进一步确定X线及CT检查对诊断周围型肺癌的临床价值，现报道如下。
1 资料与方法
1.1 一般资料
选择我院2008年12月～2010年12月收治的68例周围型肺癌患者，入选患者均行X线及CT扫描检查，均经术后病理确诊。其中男40例，女28例，年龄43～80岁，平均56.27岁；60岁以上共52例，占76.5%。病理分型：腺癌40例，鳞癌7例 ......
