【摘要】目的：觀察低劑量CT與常規(guī)劑量CT對早期肺癌的診斷價(jià)值及安全性。方法：研究時(shí)間為2021年1月—2023年1月，選取此時(shí)我院收治的38例早期肺癌患者進(jìn)行分析，均進(jìn)行常規(guī)劑量CT診斷與低劑量CT診斷。比較不同診斷方式的輻射劑量、肺結(jié)節(jié)情況、診斷準(zhǔn)確性以及圖像優(yōu)良率。結(jié)果：診斷后，低劑量CT診斷的輻射劑量低于常規(guī)劑量CT診斷（P0.05）；低劑量CT的診斷準(zhǔn)確性略高于常規(guī)劑量CT，但差異無意義（P>0.05）；低劑量CT診斷的圖像優(yōu)良率高于常規(guī)劑量CT診斷（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
