目的:探讨多层螺旋CT低剂量扫描对肺小结节的诊断价值。方法:对在我院体检行CT扫描发现的40例可以复查的肺小结节病患者的影像学资料进行分析讨论,采用首次低剂量、复查常规剂量进行胸部扫描。结果:两种扫描方案对肺部小结节的诊断无明显差异。结论:胸部常规体检可采用低剂量CT扫描,减低受检者的辐射剂量。
Objective: To investigate the value of low-dose multislice spiral CT in the diagnosis of pulmonary nodules. Methods: The imaging data of 40 patients with recurrent pulmonary sarcoidosis found in CT scan of our hospital were analyzed and discussed. The first low dose and review of conventional dose were performed on the chest scan. Results: There was no significant difference in the diagnosis of small pulmonary nodules between the two scanning schemes. Conclusion: The low-dose CT scan can be used in routine chest examination to reduce the radiation dose of the subjects.
