摘要	探讨早期肺癌筛查中采用低剂量CT扫描技术的价值。方法 2021年1月到2022年4月，选取疑似早期肺癌患者103例为对象，患者依次应用低剂量CT扫描技术、常规剂量CT扫描技术完成CT扫描，以活检病理学结果为金标准，统计两种技术的结果。结果低剂量CT扫描技术、常规剂量CT扫描技术的七项筛查指标比较无差异（P＞0.05），低剂量CT扫描技术的四项CT影像学表现检出率大于常规剂量CT扫描技术（P＜0.05）。低剂量CT扫描技术的有效剂量、容积剂量指数和剂量长度乘积均明显低于常规剂量CT扫描技术（P＜0.05）。低剂量CT扫描技术的图像噪声虽大于常规剂量CT扫描技术，图像质量评分虽低于常规剂量CT扫描技术，但差异无统计学意义（P＞0.05）。结论在早期肺癌筛查中应用低剂量CT扫描技术，筛查指标、影像学表现检出率更好。
Abstract	Objective To explore the value of low-dose CT scanning technology in early lung cancer screening. Methods: From January 2021 to April 2022, 103 patients with suspected early lung cancer were selected as subjects. The patients completed CT scanning with low-dose CT scanning technology and conventional dose CT scanning technology in turn. The results of the two technologies were counted based on the pathological results of biopsy as the gold standard. Results There was no difference in the seven screening indicators between low-dose CT scanning technology and conventional dose CT scanning technology (P>0.05). The detection rate of four CT imaging manifestations of low-dose CT scanning technology was higher than that of conventional dose CT scanning technology (P<0.05). The effective dose, volume dose index and dose length product of low-dose CT scanning technology were significantly lower than those of conventional dose CT scanning technology (P<0.05). Although the image noise of low-dose CT scanning technology is higher than that of conventional dose CT scanning technology, and the image quality score is lower than that of conventional dose CT scanning technology, the difference is not statistically significant (P>0.05).Conclusion The application of low-dose CT scanning technology in early lung cancer screening has a better detection rate of screening indicators and imaging manifestations.
