摘要:
目的 探讨低剂量CT扫描诊断早期肺癌的临床效果。方法 选择我院2019年1月31日~2020年6月30日我院收治的经术后病理诊断为早期肺癌患者97例作为研究对象，均于术前进行低剂量CT扫描及普通剂量CT扫描，比较两种剂量CT扫描对于早期肺癌的检出率、析影像学特征、图像质量评分及噪声指数、放射剂量，评价不同剂量CT扫描在早期肺癌诊断中的应用效果。结果 低剂量CT扫描对早期肺癌的检出率为93.81%，高于普通剂量CT扫描的91.75%，但差异无统计学意义（P＞0.05）；低剂量CT、普通剂量CT扫描早期肺癌的主要征象表现均为混合磨玻璃结节影、磨玻璃结节影、实性结节影、斑片状高密度影、小片状空洞，部分患者病灶边缘呈现分叶征、毛刺征，部分患者可于影像学图像中考到支气管扩张，两种主要征象比较，差异无统计学意义（P＞0.05）；低剂量CT扫描图像质量评分低于普通剂量CT，图像噪声值高于普通剂量CT，但差异无统计学意义（P＞0.05）；低剂量CT扫描DLP、CTDIw、最大有效剂量均低于普通剂量CT，差异有统计学意义（P＜0.05）。结论 低剂量CT扫描对于早期肺癌的检出率与普通剂量CT扫描相近，影像学图像特征与普通剂量CT较为一致，不会明显降低影像学图像质量、增加图像噪声值，而且能够减少扫描中的辐射剂量，具有更高应用安全性。
Abstract:
Objective To explore the clinical effect of low-dose CT scan in the diagnosis of early lung cancer.Methods 97 patients with early stage lung cancer who were admitted to our hospital from January 31, 2019 to June 30, 2020 who were diagnosed as early stage lung cancer after surgery were selected as the research objects.Both low-dose CT scans and normal-dose CT scans were performed before surgery.Compare the detection rate of early lung cancer,image analysis characteristics, image quality score and noise index, radiation dose of two dose CT scans,to evaluate the application effect of different doses of CT scan in the diagnosis of early lung cancer.Results The detection rate of low-dose CT scan for early lung cancer was 93.81%, which was higher than 91.75% of normal-dose CT scan, but the difference was not statistically significant (P＞0.05);The main signs of early lung cancer on low-dose CT and normal-dose CT scans were mixed ground glass nodules, ground glass nodules, solid nodules, patchy high-density shadows, and small cavities.Some patients showed lobular signs and burr signs on the edge of the lesion, and some patients could be tested for bronchiectasis in imaging images. There was no statistically significant difference between the two main signs (P＞0.05);The image quality score of low-dose CT scan was lower than that of normal-dose CT, and the image noise value was higher than that of normal-dose CT, but the difference was not statistically significant (P＞0.05);Low-dose CT scan DLP, CTDIw, and maximum effective dose were all lower than normal-dose CT,the difference was statistically significant (P＜0.05).Conclusion The detection rate of low-dose CT scan for early lung cancer is similar to that of normal-dose CT scan.The imaging image characteristics are more consistent with normal dose CT, which will not significantly reduce the imaging image quality and increase the image noise value, and can reduce the radiation dose in the scan, which has higher application safety.
