目的：对比分析不同放射诊断方法在肺癌与良性肿瘤的鉴别诊断中的效果。方法选择经CT诊断的肺癌及肺部良性肿瘤患者59例（ CT组），经X线胸片诊断的肺癌及肺部良性肿瘤患者58例（ X线组）的临床资料，所有患者均经术后病理诊断或经皮肺穿刺活检，分析比较CT及X线检查诊断肺癌与肺部良性肿瘤的影像学表现、特异度及灵敏度。结果在影像学表现为有毛刺或锯齿状、肺叶一侧或全肺不张方面，CT组与X线组差异具有统计学意义（P＜0．05）；两组用不同方法诊断出的肺癌及肺部良性肿瘤例数差异有统计学意义（P＜0．05），经术后病理诊断或经皮肺穿刺活检最终确诊的病例数之间的差异则无统计学意义（P＞0．05）；在诊断肺癌、肺部良性肿瘤上，CT组与X线组的敏感度、特异度差异均具有统计学意义（ P＜0．05）。结论对肺癌与良性肿瘤进行鉴别诊断，CT是良好的放射诊断方法。

Objective To evaluate the efficacy of two different radiological methods for the diagnosis of malignant lung cancer and benign lung tumor.Method 59 patients diagnosed with CT as cases of malignant lung cancer and benign lung tumor ( labeled CT group) and 58 patients diagnosed with X-ray as cases of malignant lung cancer and benign lung X-ray( labeled X-ray group) were chosen as the subjects of study.All patients were finally diagnosed with postoperative pathology or percutaneous lung puncture biopsy.Clinical data of both groups were then compared and analyzed for differences in the imaging, sensitivity and specificity.Findings Differences were identified in imaging bearing burr or serrated lobe, side or pulmonary atelectasis.The difference was statistically significant between CT group and X-ray group ( P <0.05 ). Difference was also identified in the number of cases of lung cancer and pulmonary tumor as diagnosed with the two different methods (P<0.05).The postoperative pathological diagnosis or the difference between the percutaneous lung puncture biopsy confirmed that the number of cases had no statistic significance(P>0.05).In the diagnosis of lung cancer, lung benign tumor, the difference in sensitivity and specificity between CT group and the X-ray group was statistically significant (P<0.05).Conclusion Our study indicated that CT could serve as a more desirable and effective method for diagnosis of malignant lung cancer and benign tumor.
