【摘要】目的：观察低剂量CT与常规剂量CT对早期肺癌的诊断价值及安全性。方法：研究时间为2021年1月—2023年1月，选取此时我院收治的38例早期肺癌患者进行分析，均进行常规剂量CT诊断与低剂量CT诊断。比较不同诊断方式的辐射剂量、肺结节情况、诊断准确性以及图像优良率。结果：诊断后，低剂量CT诊断的辐射剂量低于常规剂量CT诊断（P0.05）；低剂量CT的诊断准确性略高于常规剂量CT，但差异无意义（P>0.05）；低剂量CT诊断的图像优良率高于常规剂量CT诊断（P

【Abstract】Objective：To observe the diagnostic value and safety of low dose CT and conventional dose CT in early lung cancer. Methods：The study period was from January 2021 to January 2023，and 38 patients with early lung cancer admitted to our hospital were selected for analysis，all of whom were diagnosed by conventional dose CT and low dose CT. The radiation dose，pulmonary nodules condition，diagnostic accuracy and image excellent rate of different diagnostic methods were compared.Results：After diagnosis，the radiation dose of low-dose CT diagnosis was lower than that of conventional CT diagnosis （P0.05）；The diagnostic accuracy of low dose CT was slightly higher than that of conventional CT，but the difference was not significant （P>0.05）；The excellent and good image rate of low dose CT diagnosis was higher than that of conventional CT diagnosis （P
