低剂量CT与常规剂量CT对早期肺癌的诊断效果对比

Diagnostic effect comparison between low-dose CT and conventional dose CT on early stage lung cancer

目的研究在早期肺癌诊断中采取低剂量CT与常规剂量CT对效果的影响。方法本次采取双盲法将本院从2017年4月～2018年4月期间收治的60早期肺癌患者分为两组,每组30例,对照组行常规剂量CT检查,实验组行低剂量CT检查,对比两组诊断价值。结果对照组早期肺癌患者诊断准确率(93.33%)低于实验组的96.67%,但差异无统计学意义(P>0.05)。实验组早期肺癌患者最大有效辐射剂量为(0.68±0.12)mSV、权重CT剂量为(1.78±0.33)mGy、满意度评分为(94.22±5.33)分,与对照组比较,差异有统计学意义(P<0.05);但实验组早期肺癌患者图像质量为(3.55±0.58)分,与对照组的(3.60±0.88)分比较,差异无统计学意义(P>0.05)。结论将低剂量CT与常规剂量CT扫描应用于早期肺癌诊断中均存在一定效果,但低剂量CT诊断价值更显著。

Objective To study the effect of low-dose CT and conventional dose CT on the diagnosis of early lung cancer.Methods A total of 60 patients with early stage lung cancer admitted from April 2017 to April 2018 were divided into two groups double-blindly,30 cases in each group.The control group was given routine dose CT examination and the experimental group was given low-dose CT examination.The diagnostic value of the two groups was compared.Results The diagnostic accuracy of the control group(93.33%)was lower than that of the experimental group(96.67%),but the difference was not statistically significant(P>0.05).The maximum effective radiation dose was(0.68±0.12)mSV,weight CT dose was(1.78±0.33)mGy,satisfaction score was(94.22±5.33)scores in the experimental group,which were significantly different from those in the control group(P<0.05).There was no significant difference in the image quality between the experimental group(3.55±0.58)scores and the control group(3.60±0.88)scores(P>0.05).Conclusion Low-dose CT and conventional dose CT scan have certain effects in the early diagnosis of lung cancer,but the diagnostic value of low-dose CT is more significant.
