目的探讨中央型肺癌胸部X线片与CT的诊断对比。方法选取宜阳县人民医院2009年1月至2012年12月65例中央型肺癌患者,均应用胸部X线与CT检查,分析对比两种方法的诊断结果。结果胸部X线片诊断率为64.62%,CT诊断率为92.31%,两组比较差异有统计学意义(P<0.05);CT显示肺门区肿块、纵隔淋巴结肿大更为清晰(P<0.05)。结论 CT显示病变细节更具有优势,在胸部X线片疑似肺癌患者中常作为进一步检查法应用。 Objective To investigate the diagnostic value of chest radiography and CT in central lung cancer. Methods Sixty-five patients with central lung cancer from January 2009 to December 2012 in Yiyang County People’s Hospital were enrolled in this study. Chest X-ray and CT were used to analyze and compare the diagnostic results of the two methods. Results The diagnostic rate of chest X-ray was 64.62%, the diagnostic rate of CT was 92.31%, there was significant difference between the two groups (P <0.05). CT showed hilar mass and mediastinal lymph node enlargement more clearly (P <0.05 ). Conclusions CT showed more details of the lesion and was often used as a further test in patients with suspected lung cancer on chest radiographs.
