目的 探讨螺旋CT对治疗肺癌的 临床价值，为肺癌研究提供可靠依据。方 法 选取我院2011年5月至2013年5月门诊 及住院部102例肺癌患者作为研究对象， 将所有患者的螺旋CT诊断结果和术后病理 检查进行比较，以确定诊断结果的准确 度。结果 肺癌患者螺旋CT分期与临床分 期结果无显著性差异；肺癌患者螺旋CT的 征象与手术病理诊断结果情况无显著性差 异；CT的肺癌分期和检出率与病理检查高 度一致。结论 螺旋CT应用于诊断肺癌可 以提高肺癌的检出率，有利于患者的及时 治疗，值得临床医学的进一步推广与应 用。

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 Spiral CT for lung cancer staging and clinical staging result there was no significant difference. A sign of lung cancer patients with spiral CT and surgical pathology diagnosis case there was no significant difference. CT of lung cancer classification and detection rate highly consistent with pathological examination. 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.
