摘要：
目的 对比分析在中央型肺癌诊断中应用CT扫描和X线胸片两种检查方法的结果。方法 选取2013年11月至2016年3月我院收治的95例已确诊为中央型肺癌的患者，所有患者分别予以双肺CT扫描和胸部X线片，比较两种方法检查后中央型肺癌检出率及肺门区肿块、综合淋巴结肿大、支气管腔内影像表现显示情况。结果 CT扫描检查后确诊中央型肺癌阳性患者89例，占93.68%;胸部X线片检查后确诊阳性患者38例，占40.00%，CT扫描明显高于胸部X线片，差异具有统计学意义(χ² =61.766，P<0.05)。CT扫描发现肺门区肿块患者77例，占81.05%，综合淋巴结肿大53例，占55.79%，支气管腔内肿块76例，占80.00%，胸部X线发现肺门区肿块患者37例，占38.95%，综合淋巴结肿大33 例，占34.74%，支气管腔内肿块43例，占45.26%，CT扫描肺门区肿块、综合淋巴结肿大和支气管腔内诊断率均高于胸部X线，差异具有统计学意义(P<0.05)。结论 CT扫描和X线胸片均在中央型肺癌的诊断中具有一定效果，但CT扫描准确率更高，分辨率高，扫面层次清晰，较好地对临床诊断提供支持作用，临床参考价值更大，为患者尽早治疗和预后提供保障。

ABSTRACT: Objective To contrast the two methods of CT scan and X-ray in the diagnosis of central type lung cancer. Methods Ninety-five patients diagnosed with central type lung cancer from November 2013 to March 2016 in our hospital were selected as the research objects, the patients were both diagnosed with CT scans and chest X-ray scan, the detection rate of central type lung cancer, pulmonary hilum mass, the integrated lymphadenopathy and endobronchial imaging findings of the two methods were compared. Results Eighty-nine cases of patients with central lung cancer-positive were diagnosed by the CT scan, which was accounted for 93.68%; 38 cases patients were confirmed positive by chest X-ray scan diagnosis, which was accounted for 40.00%, the detection rate of CT scan was obviously higher than that of the chest X-ray, the difference was statistically significant （x2=61.766，P<0.05). CT scans showed that 77 cases patients were checked with pulmonary hilum mass which was accounted for 81.05%, 53 cases were the integrated lymphadenopathy for 55.79%, endobronchial mass in 76 cases with 80.00%, while the chest X-ray scan found that pulmonary hilum mass in 37 cases (accounting for 38.95%), the integrated lymphadenopathy in 33 cases (accounting for 34.74%), endobronchial mass in 43 cases (accounting for 45.26%), the diagnosis rate of pulmonary hilum mass, the integrated lymphadenopathy and endobronchial mass of CT scan were higher than those of chest X-ray scanning, all the differences were statistically significant (P<0.05）. Conclusion CT scans and X-ray diagnosis have some effect in the detection of central lung cancer, but CT scans has higher accuracy, higher resolution, clear sweep the surface level, which is preferable to provide support for clinical diagnosis with large clinical reference value, and provide protection for early treatment and prognosis.
