目的比较中央型肺癌X线胸片与CT检查的应用价值。方法对我院自2006年3月至2010年5月收治的84例经病理检查证实的中央型肺癌患者的临床资料进行回顾性分析,本组患者同期进行X线胸片及CT检查,比较两种方法的诊断符合率。结果经过X线胸片及CT检查与最终病理检查结果对照,本组84例患者X线胸片确诊61例,确诊率为72.6%;CT检查确诊75例,确诊率为89.3%。两种检查方法确诊率比较有统计学差异(χ2=16.528,P<0.01),具有统计学意义。同时CT检查还可现实X线胸片不可见的管腔变窄、纵膈淋巴结肿大等。结论 CT检查较X线胸片对中央型肺癌临床确诊率高,且视野宽阔、分辨度高,是临床应用辅助诊断中央型肺癌的重要方法 。
Objective To compare the application value of central chest X-ray and CT examination. Methods The clinical data of 84 patients with central lung cancer confirmed by pathology from March 2006 to May 2010 in our hospital were retrospectively analyzed. The patients underwent X-ray and CT examinations in the same period, Method of diagnosis of coincidence rate. Results X-ray and CT examination and final pathological examination results, the group of 84 patients with X-ray diagnosis of 61 cases, the diagnosis rate was 72.6%; CT confirmed 75 cases, the diagnosis rate was 89.3%. The diagnostic accuracy of the two methods were statistically significant (χ2 = 16.528, P <0.01), with statistical significance. At the same time CT examination can also be realistic X-ray invisible lumen narrowing, mediastinal lymph nodes and so on. Conclusion Compared with X-ray, the diagnostic accuracy of CT in central lung cancer is high, and its visual field is wide and its resolution is high. It is an important method to diagnose central lung cancer with clinical application.
