摘　　要：目的:探讨16排螺旋CT低剂量扫描技术在肺部相关疾病诊断中的价值。方法:回顾性分析43例行16排螺旋CT低剂量技术扫描的患者图像资料,评价其图像质量。结果:所有患者均按照要求完成检查,图像质量级别良好以上,噪声虽有增大,但不影响解剖结构的显示,能够满足对肺部相关疾病的诊断要求。结论:肺部多排螺旋CT低剂量扫描在提高病变检出率的同时,能够减少患者的辐射剂量,延长球管的使用寿命,降低维修费用,值得进一步推广。Objective: To discuss the value of low dose scanning technique of 16-slice spiral CT for the diagnosis of pulmonary diseases. Methods: A retrospective analysis was adopted to analyze 43 image documents were scanned by 16-slice spiral CT and to evaluate their qualities. Results: All of patients were examined in accordance with the requirements and allof image qualities were more than good. Although their background noise were increased, theimage quality did not affect the display of anatomical structure. Therefore, it can satisfy the requirements for the diagnosis of pulmonary diseases. Conclusion: The pulmonary multi-slicespiral CT based on low-dose scanning technology can improve the detection rate of lesions,reduce radiation dose for patients, prolong the service life of the tube and reduce the maintenance cost, therefore it is worthy for further promotion.
