早期肺癌患者行低剂量CT与常规剂量CT检查的对比研究分析

Comparative Study and Analysis of Low Dose CT and Routine Dose CT Examination for Early Lung Cancer Patients

目的对比分析对早期肺癌患者采用低剂量CT与常规剂量CT检查的诊断效果。方法回顾分析2020年1月—2022年12月本院接收的50例早期肺癌患者,所有患者首次接受检查应用低剂量CT、间隔2周后复查应用常规剂量CT检查,对比不同检查方法的诊断准确率、辐射相关指标、CT扫描图像质量等指标。结果患者低剂量CT检查诊断准确率高于常规剂量CT检查,但数据对比无统计学意义(P>0.05);低剂量CT检查的辐射相关指标均低于常规剂量(P<0.05);低剂量CT检查的图像质量优良率高于常规剂量,但数据对比无统计学意义(P>0.05)。结论对早期肺癌患者实施检查诊断,应用低剂量CT与常规剂量CT检查,在诊断准确率以及图像质量方面较为接近,均可达到有效的诊断效果。但低剂量CT检查对患者的辐射伤害性较小,安全性更高,值得进一步推广应用。

Objective To compare and analyze diagnostic effect of low-dose CT and routine dose CT examination for early lung cancer patients.Methods The paper reviewed and analyzed clinical data of 50 confirmed early lung cancer patients in our hospital from January 2021 to December 2022,treated with low-dose CT examination for the first time and routine dose CT examination after a 2-week interval.Diagnostic accuracy,radiation related indicators,and CT scan image quality of different examination methods were compared.Results After examination,diagnostic accuracy of low-dose CT examination was higher than routine dose CT examination,data comparison was not statistically significant(P>0.05).Radiation related indicators of low-dose CT examination were lower than routine dose(P<0.05).Image quality improvement rate of low-dose CT examination was higher than routine dose,data comparison was not statistically significant(P>0.05).Conclusion Low-dose CT and routine dose CT examination can achieve effective diagnostic effect in terms of diagnostic accuracy and image quality for early lung cancer patients,however,low-dose CT examination can achieve less radiation damage and higher safety,which is worthy of further promotion and application.
