低剂量CT检查在肺癌筛查中的应用

目的探讨低剂量CT检查在肺癌筛查中的应用。方法选择390例体检者,应用肺部低剂量CT检查和X光胸片检查。记录CT检查发现结节性病灶体检者的例数和X光胸片检查发现结节性病灶体检者的例数。结果 CT检查发现结节性病灶体检者40例,X光胸片检查发现结节性病灶体检者19例。两种检查方式显示的结果有显著差异(P<0.05)。结论低剂量CT检查的异常率高于X光胸片,可作为肺癌筛查的方法。

Objective To investigate the application of low dose CT in lung cancer screening.Method Three hundred and ninety examinees were chose.The lung of the examinees were examined through low dose CT and X-ray chest radiograph.The number of the examinees in whose lung focal nodules were found through low dose CT and X-ray chest radiograph were recorded.Results Focal nodules were found through low dose CT in forty examinees. Focal nodules were found through X-ray chest radiograph in nineteen examinees.There was signiifcantly difference between two Examination.Conclusion The abnormal rate of using low dose CT is higher than it using X-ray chest radiograph. Low dose CT can be applied in lung cancer screening.
