目的探究螺旋CT诊断肺癌的临 床应用价值，为临床治疗肺癌提供可靠依 据。方法 选取我院2011年5月-2013年5月 门诊及住院部102例肺癌患者作为研究对 象，所有患者均经过多层螺旋CT诊断，并 和术后病理组织学的结果进行比较，观察 诊断结果的准确率。结果 患者多层螺旋 CT与病理检查结果比较，多层螺旋CT检出 率明显高于病理检查，p＜0.05，差异具 有统计学意义；多层螺旋CT误诊率与病理 检查比较，多层螺旋误诊率明显低于病理 检查，p＜0.05，差异具有统计学意义。 结论 采用螺旋CT诊断肺癌具有十分重要 的临床价值，可提高肺癌的检出率，但是 其只在早期肺癌诊断中准确率较高，而在 中后期肺癌诊断中存在一定的缺陷，因而 要结合多种诊断方式进行确诊，为临床治 疗肺癌提供可靠依据。

Objectives to explore clinical value of spiral CT in the diagnosis of lung cancer, and to provide reliable basis for clinical treatment for lung cancer. Methods 102 patients with lung cancer admitted by the outpatient service and inpatient department of this hospital were selected as research subjects, all patients were subject to multiple-layer spiral CT, and results of postoperative pathologic histology were compared, the accuracy of diagnosis results was observed. Results According to the comparison in multiple layer spiral CT and pathologic examination results in patients, the detection rate of multiplelayer spiral CT was much higher than that in pathological examination, p<0.05, and the difference was statistically significant. The misdiagnosis rate of multiple-layer spiral CT was significantly lower that that of pathologic examination when compared, p<0.05, and the difference was statistically significant. Conclusions The application of spiral CT derivers extremely important clinical value in the diagnosis of lung cancer, and it can improve the detection rate of lung cancer, but its accuracy is only higher in early diagnosis of lung cancer, and there are certain defects in the diagnosis of lung cancer during later period, thus multiple diagnostic methods have to be combined to conduct diagnose so as to provide reliable basis for clinical treatment of lung cancer.
