低剂量CT在肺癌术后短期复查中的应用价值

Application value of low-dose CT in a short-term review of lung cancer after operation

    摘要
  • 摘要:
      目的   通过常规CT和低剂量CT的对比研究，探讨低剂量CT在肺癌术后短期复查中的应用价值。
      方法   83例肺癌术后短期内复查CT的患者，50例（A组）行常规CT扫描，33例（B组）行低剂量CT扫描。分别从图像质量和临床需求角度出发对所有CT图像进行评分，并记录每个病例的辐射剂量指标CTDIvol、DLP。比较二组之间的评分和辐射剂量是否存在显著性差异。
      结果   二组在图像质量方面的平均得分分别为3.705±0.314、3.311±0.442，在临床需求方面的平均得分为2.670±0.373、2.561±0.410，CTDIvol分别为（19.248±1.532）mGy、（10.138±1.113）mGy，DLP分别为（170.180±19.259）mGy*cm、（99.061±14.504）mGy*cm。二组在图像质量、CTDIvol、DLP方面均存在显著性差异，在临床需求评分方面无显著性差异。
      结论   低剂量CT完全能满足临床对于肺癌术后短期复查的需求，并明显降低了辐射剂量。

     

    Abstract:
      Objective   To explore the application value of low-dose CT in lung cancer after operation in a short-term review by comparing conventional and low-dose CT.
      Methods   In 83 cases of lung cancer during the immediate postoperative period review, 50 cases (group A) underwent conventional CT scanning, whereas 33 cases (group B) underwent low-dose CT scanning. All CT scans were scored on the basis of image quality and clinical needs. The radiation dose indexes CTDIvol and DLP were recorded for each case. A comparison of the score and radiation dose between the two groups helped determine the existence of significant differences.
      Results   The average image quality scores of the two groups were 3.705±0.314 and 3.311±0.442, those for clinical demand were 2.670±0.373 and 2.561±0.410, those for CTDIvol were (19.248±1.532) mGy and (10.138±1.113) mGy, and those for DLP were (170.180±19.259) mGy*cm and (99.061±14.504) mGy*cm. The two groups exhibited significant differences in image quality, CTDIvol, and DLP but revealed no significant dissimilarity in clinical demand.
      Conclusion   Low-dose CT completely meets the clinical requirements for short-term follow-up after resection of lung cancer and significant reduction in radiation dose.
