摘　　要：目的研究探讨低剂量与常规剂量6排螺旋CT诊断肺癌的临床价值。方法将我院收治的368例肺癌高危患者随机均分为两组,低剂量组184例行低剂量肺癌筛查,常规剂量组184例行常规剂量肺癌筛查。随访跟踪5年,统计比较肺癌筛查率、漏诊率、特异性和敏感性等指标。结果低剂量组总检出率为38.0%,常规剂量为38.5%两组诊断敏感性分别为78.6%、80.3%,三年累计检出率分别是25.4%、24.8%,五年生存率为37.2%、37.9%,确诊病例的组织分型、分期比较,组间差异均无统计学意义(P>0.05)。结论低剂量6排螺旋CT能有效诊断肺癌,并降低人体辐射量,安全高效。Objective To investigate the clinical value of low-dose and conventional-dose 6-slice spiral CT in the diagnosis of patients with lung cancer.Methods 368 patients with lung cancer were randomly and evenly divided into two groups,which were treated with low-dose group and conventional-dose lung cancer screening.They were given a 5-year follow-up and their lung cancer screening rate,misdiagnosis rate,specificity and sensitivity of the indicators were analyzed.Results The total detectable rates were 38.0% and 38.5%,and the diagnostic sensitivities were 78.6% and 80.3% respectively in the low-dose group and in the conventional-dose group.The 3-year detectable rates were 25.4% and 24.8% and the 5-year survival rates were 37.2% and 37.9% respectively in the low-dose group and in the conventional-dose group.The differences of tissue types and related indexes showed no statistical significance between the two groups（P0.05）.Conclusion Low dose 6-slice spiral CT can diagnose lung cancer effectively and reduce the amount of human radiation.
